Amazon SES alternative in 2026: 13 transactional email APIs, ranked and priced

Editorial team · updated 24 September 2026 · facts checked 24 September 2026

By our transactional email rating, out of 100, the five highest-rated email APIs are SendPulse (83.7), Brevo (80.0), Mailgun (78.6), Mailtrap (78.5) and Resend (78.0); Amazon SES places 10th of 14. Nine alternatives keep a free plan with no end date; SES has none. SES keeps the lowest paid price: $1.00 for 10,000 emails a month, $10 for 100,000.

The list covers the other 13 transactional email providers in our dataset, in the order of the score behind our transactional email API rankings. That score weighs pricing and free tier (30%), developer and AI readiness (30%), reviews on Trustpilot, G2 and Capterra (25%) and email features (15%); the methodology page lists every criterion. Amazon SES scores 66.7. It gets full marks for price, but loses most of the free-access points (credits only, no free plan), every OAuth and idempotency point, and part of the review score. Where neighboring scores differ by a point or less, read the ranks as near-ties: a single new fact can swap them. Every score, rank and order on this page is read from the live ranking (methodology version 2026.09, preliminary), so it follows each card and weight change.

We built this page from our provider cards, and on 24 September 2026 we re-read the AWS pages behind every SES claim below: the SES pricing page, the SES FAQ, the production-access page, the SendEmail reference, the credentials page and the AWS MCP Server setup guide. Nobody on the editorial team opened an account or sent an email, so nothing here describes delivery speed or inbox placement.

Amazon SES alternatives compared

Amazon SES first as the baseline, then the alternatives in rating order. Prices are monthly list prices in USD before tax for the cheapest plan that covers 10,000 emails, the site's scoring scenario. Facts come from our provider cards, checked 23–24 September 2026.

"Client credentials only" means the app gets a token for its own account and can't act for another user's account. "Replay check" means the vendor documents a signed timestamp or token you can use to reject old deliveries. SES has no webhook of its own: events go to Amazon SNS, EventBridge, CloudWatch or Firehose, and SNS signs what it posts to your HTTPS endpoint. Zenvia's SMTP relay is not verified in our data.

Why developers look for an Amazon SES alternative

The four points below come from AWS's own pages. They overlap with the SES questions AI search engines researched for this topic: free tier and pricing, getting started, and the sandbox and production access.

Setup runs through AWS identity and a sandbox. The SES API takes AWS access keys, and every request carries a Signature Version 4 signature derived from them; the AWS SDKs and CLI sign for you. The SMTP interface uses a separate user name and password that AWS calls "a type of IAM credentials", and they are unique to each Region. Each From or Return-Path address must be a verified identity. New accounts start in the sandbox, and sandbox status is "unique per each AWS Region": mail goes only to verified addresses or the mailbox simulator, at most 200 messages per 24 hours and 1 per second, per the production-access page. To leave it you file a request with your mail type, website URL and an acknowledgement that you handle bounces and complaints; AWS Support "provides an initial response to your request within 24 hours", and longer if it needs more information. Delivery events reach your app through an SNS subscription or another AWS service, not a webhook URL set on SES.

There is no permanent free tier. The SES pricing page lists no always-free email quota. It says new AWS customers "will receive up to $200 in AWS Free Tier credits" usable on SES; AWS's billing docs add that a payment method is required and credits expire 12 months after the account is created. The SES FAQ still offers "up to 3,000 message charges for free each month for the first 12 months", which the pricing page does not repeat, and neither page says which accounts get it. Nine of the 13 alternatives have a free plan with no end date; our free email API tiers comparison covers their daily caps.

SendEmail has no idempotency key. The SendEmail reference (POST /v2/email/outbound-emails) lists body fields for content, recipients, configuration set, tags, tenant and addresses, and nothing that de-duplicates a request; the SES v2 API model has no idempotency token either. The only client tokens in AWS's email models sit on Mail Manager create calls, which don't send mail. If a send times out, your code can't tell whether SES accepted it, and a retry can deliver the receipt twice. Bird, Brevo, Resend and Telnyx accept a key on their send call; our idempotency key explainer shows how the mechanism works.

The price list changed shape in 2026. À la carte pricing is $0.10 per 1,000 outbound emails, charged per recipient, plus $0.12 per GB of attachment data. Next to it AWS now sells three plans: Essentials at $0.16 per 1,000 with no monthly fee, Pro at $105 per account per Region per month plus $0.22 per 1,000, and Enterprise at $500 plus $0.23 per 1,000, with lower rates above 10 million emails. The pricing page's footnote says new accounts, and account-Region pairs with no metered SES activity since 1 June 2025, "will start on the Essentials plan beginning July 21, 2026", and "You can upgrade or switch to à-la-carte pricing at any time." An account that keeps the default pays $1.60 for 10,000 emails instead of $1.00. Pro bundles managed dedicated IPs and email validation that à la carte customers buy separately.

Price alone is a weak reason to leave SES. At 10,000 emails a month the median price across our email providers is $15.00, fifteen times SES's à la carte price, and at 100,000 no alternative in the dataset costs less than SES's $10.

The 13 alternatives, in rating order

Each block says what changes if you move from SES, with the rating, its coverage (the share of the rating's weight backed by verified facts) and the price at 100,000 emails next to SES's $10. "Watch out" repeats weaknesses from the provider's card.

SendPulse

Rating 83.7, coverage 99 %. The free plan covers 12,000 emails a month, capped at 400 a day and 50 an hour, with no card; 100,000 emails cost $74.85 on Pro (USD from an Internet Archive capture of the US pricing page, because the live page shows the visitor's currency). Instead of SigV4, the REST API exchanges a client ID and secret for a one-hour token (OAuth client credentials). Instead of the sandbox request, moderators approve the SMTP profile, which "usually takes up to 24 hours". The remote MCP server can send through the SMTP API, and the same account sells SMS and WhatsApp.

Watch out: webhooks are not signed, credentials can't be limited to sending the way an IAM policy limits ses:SendEmail, there is no idempotency key and no inbound email. SendPulse card

Brevo

Rating 80.0, coverage 99 %. The free plan sends 300 emails a day with no time limit after Brevo approves the account, and free-plan emails carry a "Sent with Brevo" sticker. Starter costs $17 at 10,000 and $82 at 100,000. Transactional sends accept an idempotency key kept 30 minutes, which SES lacks. Core hosting is in the EU for every account. OAuth uses the authorization-code flow, but only for users inside your own Brevo organization.

Watch out: webhooks are not signed (Brevo offers IP allowlisting, URL credentials or a bearer token), and the official MCP server manages contacts, campaigns and templates but sends no transactional email. Brevo card

Mailgun

Rating 78.6, coverage 98 %. The free plan sends 100 emails a day; Basic costs $15 for 10,000 and Foundation $75 for 100,000. Authentication is a plain API key over HTTP Basic, and a Domain Sending Key can only send, for one domain, the closest match to an IAM policy scoped to ses:SendEmail. Webhooks are HMAC-signed over a timestamp and a random token, and Mailgun suggests caching the token to refuse replays. You pick a US or EU region.

Watch out: no OAuth, no idempotency key, and new accounts send from a sandbox domain to at most 5 authorized recipients until you add your own domain. Mailgun card

Mailtrap

Rating 78.5, coverage 99 %. The free plan covers 4,000 emails a month and 150 a day, shared with received mail. Basic costs $15 for 10,000 and $30 for 100,000. Tokens carry per-resource permissions down to one sending domain, webhooks are HMAC-signed, and the local MCP server sends email and manages templates. Each sending domain passes an automatic compliance check, and new accounts are held to 150 emails an hour.

Watch out: data is hosted only in the US, the webhook signature carries no timestamp, and there is no OAuth or idempotency key. Mailtrap card

Resend

Rating 78.0, coverage 100 %. The free plan allows 3,000 emails a month and 100 a day, counting received mail and every recipient; Pro costs $20 for 50,000 and $35 for 100,000. Resend states that no production approval is needed. It documents OAuth with PKCE, sending-only API keys, an Idempotency-Key kept 24 hours (also as an SMTP header), Svix-signed webhooks with a timestamp, and a hosted MCP server.

Watch out: email only, all stored data sits in the US, and 31 reviews across aggregators make a thin review base. Resend card

Bird

Rating 77.8, coverage 98 %. The free plan gives 1,000 emails a month, 50 a day, one domain. Startup costs $15 for 50,000 and $30 for 100,000. Bird covers each developer column in the table: OAuth with authorization code and PKCE, an Idempotency-Key kept about three hours, Standard Webhooks signatures with guidance to reject deliveries older than five minutes, keys scoped per product, and an MCP server that sends once the user signs in. Organizations are pinned to a US or EU region at sign-up.

Watch out: a small review base, with 1.6 on Trustpilot from 22 reviews. Bird card

SMTP2GO

Rating 76.7, coverage 99 %. Free covers 1,000 emails a month and 200 a day, throttled to 25 an hour until a sender domain is verified. Starter costs $15 for 10,000; Professional $75 for 100,000 with a dedicated IP. API keys can be limited to named endpoints, and the remote MCP server can send if the key allows it. Accounts sit in a US, EU or Australian data center.

Watch out: webhooks are not signed, there is no inbound email (SES receives mail), no OAuth and no idempotency key. SMTP2GO card

Telnyx

Rating 73.9, coverage 97 %. The Email API is in beta and billed as you go at $0.30 per 1,000 up to 10,000 a month: $3 at 10,000 and $25 at 100,000, the closest paid price to SES in the dataset. There is no free plan, only a $5 trial credit. Telnyx documents OAuth, Ed25519-signed webhooks with a five-minute window for email, an Idempotency-Key on email sends kept 24 hours, and remote and local MCP servers; SMS and WhatsApp sit in the same account.

Watch out: there is no SMTP relay, so tools that take only SMTP credentials can't use it, and the Email API and its rates are labeled beta. Telnyx card

Mailjet

Rating 72.8, coverage 98 %. Free sends 6,000 emails a month, 200 a day. Starter is $9 for 8,000, so 10,000 costs $14.16 with overage; 100,000 needs Premium at $112. Customer data stays in the EU. Inbound parsing needs Premium 50k or above.

Watch out: webhooks are not signed (Mailjet recommends basic auth in the URL), Email API keys have full access, and the official MCP server is read-only: Mailjet says it "does not send emails". Mailjet card

Infobip

Rating 66.7, coverage 97 %. Infobip starts with a 60-day trial of up to 100 messages per channel, sent only to addresses verified at sign-up, then pay as you go at $0.87 per 1,000: $8.70 at 10,000, $87 at 100,000. API keys take scopes such as email:message:send, an expiry date and allowed IPs. The REST API's OAuth is client credentials only; the per-product MCP servers support OAuth 2.1.

Watch out: no permanent free tier, webhook signing is opt-in with no replay window, and there is no idempotency key. Infobip card

Postmark

Rating 61.8, coverage 99 %. The free developer plan is 100 emails a month; Basic costs $15 for 10,000, and the next tier that covers 100,000 is Basic 125K at $115. Until manual approval the account sends only to its own verified domains, Postmark's version of the SES sandbox. The official local MCP server can send.

Watch out: "Postmark does not currently support HMAC webhook signature verification", there is no OAuth, server tokens have no sub-scopes, scheduling isn't available and inbound processing is not on Basic. Postmark card

SendGrid

Rating 56.4, coverage 99 %. New accounts get a 60-day trial at 100 emails a day, after which sending stops without a paid plan. Essentials costs $19.95 for up to 50,000 emails and $34.95 for 100,000. It is compared with SES in its own section below.

Watch out: no OAuth, no idempotency key, and Twilio's MCP server only searches the docs. SendGrid card

Zenvia

Rating 40.9, coverage 84 %. Zenvia is a Brazilian platform that sells email in BRL and MXN packages from R$100 a month in Brazil, next to WhatsApp and SMS. There is no US price list, no free tier and no Zenvia-published MCP server. It fits a team already using Zenvia for WhatsApp in Brazil or Mexico.

Watch out: webhooks are not signed, there is no OAuth and API tokens have no scopes. Zenvia card

Amazon SES vs SendGrid

SES costs less at both volumes, and the two ratings are 10.3 points apart. SendGrid authenticates with a single API key, posts events to your URL directly and signs them with ECDSA, and its Mail Send API schedules sends up to 72 hours ahead; SES needs signed requests, routes events through another AWS service and has no send-time field. Neither offers OAuth for its sending API or an idempotency key. Both limit new accounts: the SES sandbox allows only verified recipients in each Region, and SendGrid's trial allows 100 emails a day for 60 days. Our SendGrid alternatives page covers SendGrid's trial change and pairings with Postmark and Brevo.

Stay on Amazon SES if…

• You send at volume. At 100,000 emails a month SES à la carte costs $10; the next paid options in our data are Telnyx at $25 (beta rates) and Mailtrap and Bird at $30. On the subscription plans, the per-email rate falls above 10 million emails a month.
• Your app already runs on AWS. IAM policies can restrict ses:SendEmail with condition keys such as ses:FromAddress and ses:Recipients, requests can be signed with temporary STS credentials instead of long-lived keys, and events can go to EventBridge, CloudWatch or Firehose instead of an HTTPS endpoint.
• You receive email on your own domain. SES receiving runs in 22 Regions and hands messages to S3, SNS or Lambda. SendPulse and SMTP2GO have no inbound email, Mailjet parses inbound mail only from Premium 50k, and Postmark excludes it from Basic.
• You need a particular Region. The SES API runs in 29 Regions, including São Paulo, Frankfurt and Ireland, and AWS says it won't move content out of the Regions you choose without your agreement. There is no Mexico Region.
• Your coding agent already uses AWS tooling. The AWS MCP Server connects with OAuth or SigV4, and AWS's amazon-ses skill walks an agent through identity setup, production access and a first test send. The server is AWS-wide: it reaches SES through a sandboxed script tool running with your IAM credentials.

How to choose an Amazon SES alternative

1. Do you want to run for free? Nine alternatives keep a free plan; compare the daily cap with your busiest day, not the monthly total (free email API tiers).
2. Are you leaving to avoid an account review? Most alternatives have one. Brevo approves accounts before sending, SendPulse moderates the SMTP profile, Postmark reviews new accounts by hand, Mailtrap checks each sending domain, SMTP2GO throttles until a domain is verified, and Mailgun's sandbox domain reaches 5 recipients. Resend states that no production approval is needed.
3. Do you retry failed sends? Only Bird, Brevo, Resend and Telnyx let the provider drop a duplicate for you.
4. Will your app act for your customers' accounts? That needs OAuth with the authorization-code flow: Bird, Resend or Telnyx, or Brevo inside your own organization. Background: OAuth for AI agents and MCP.
5. Do you verify webhooks? Mailgun, Resend, Bird and Telnyx document a signed timestamp or token for replay checks. Six alternatives sign nothing.
6. Do you only have an SMTP field to fill in? Every alternative except Telnyx and Zenvia documents an SMTP relay: Telnyx has none, and Zenvia's is not verified in our data. Email API vs SMTP relay explains the trade-off, and our Lovable and Supabase tutorial shows a custom-SMTP setup.
7. Will an AI agent send the email? Pick a provider whose MCP server can send, and give it the narrowest key available. The AI readiness dataset lists MCP servers and skills for every provider, and email MCP servers compared covers what each one can do.

Moving off Amazon SES: what to carry over

1. DNS records. Add the new provider's SPF and DKIM records next to the SES DKIM CNAMEs and custom MAIL FROM records, and remove the old ones after cut-over. The transactional email guide covers the records and the Gmail and Yahoo sender rules.
2. Suppressions. Export the account-level suppression list in each Region you used, so the new provider doesn't mail addresses that bounced or complained. SES's global suppression list can't be queried, so those addresses won't be in the export.
3. Templates. SES stored templates use Handlebars conditionals, loops and partials; plan to rebuild them in the new provider's syntax.
4. Event handling. Replace the SNS subscription or EventBridge rule with the new provider's webhook, and move signature checks from the SNS certificate to the provider's secret or public key.
5. Credentials. Deactivate the IAM access keys and Region-specific SMTP credentials you no longer need.

About this page

The PingMyUsers editorial team wrote this page under the rules on the methodology page; the directory is operated by Sensaria AG in Switzerland. Order follows the computed rating, not a commercial relationship, and no provider paid for placement or reviewed the text. We did not create accounts or send email. Report an error to contact@sensaria.ch; corrections are dated and sourced.

Methodology

The rating is the directory's category score for transactional email (methodology version 2026.09, preliminary): pricing and free tier 30, developer and AI readiness 30, reputation 25, email features 15. Unknown facts drop out and the remaining weights renormalize; coverage shows how much of the weight is backed by verified facts. The methodology was revised on 24 September 2026: OAuth, MCP servers and agent skills now weigh more inside developer and AI readiness, webhook signing, scoped keys and assistant-app listings less, and the free tier is half of the email pricing component. These changes favor providers with OAuth, an MCP server and a free plan, which SendPulse has; SES, with credits instead of a free plan, earns a fifth of the free-tier points. The methodology page lists each change with its date. Any OAuth 2.0 grant the API documents earns full OAuth credit, client credentials included (SendPulse, Infobip); Brevo's private-only OAuth and OAuth that exists only for an MCP server, as on the AWS MCP Server that SES uses, score half. The 10,000-email price is the scoring scenario: the cheapest public plan that covers the volume, overage included, in USD; the 100,000 figures in the blocks are the second scenario. SES is scored on à la carte, its cheapest option. Review figures are aggregator snapshots from 23 and 24 September 2026; SES's Trustpilot figure is the company listing for all of AWS. MailerSend, ZeptoMail and SparkPost came up in the AI searches we reviewed for this topic but are not in our dataset, so the page gives them no score. Section order follows 200 searches ChatGPT and Gemini ran on email pricing, free tiers, SMTP and setup, pooled from four earlier research runs. The engines also retrieved Reddit threads, which returned an access error when we tried to open them on 24 September 2026, so the page quotes no forum posts.

Frequently asked questions

What is the best Amazon SES alternative?

By our transactional email rating, the three highest-rated email APIs are SendPulse (83.7), Brevo (80.0) and Mailgun (78.6). No alternative costs less than SES at 100,000 emails a month, so the right pick depends on whether you need a free plan, OAuth, idempotency keys or simpler setup.

Is there a free alternative to Amazon SES?

Yes. Nine alternatives keep a free plan with no end date: SendPulse (12,000 emails a month), Mailjet (6,000), Mailtrap (4,000), Resend (3,000), Brevo (300 a day), Bird (1,000 a month), SMTP2GO (1,000), Mailgun (100 a day) and Postmark (100 a month).

Does Amazon SES have a free tier?

Not a permanent one. New AWS customers get up to $200 in credits usable on SES, and a payment method is required. The SES FAQ still mentions 3,000 free message charges a month for the first 12 months, which the pricing page does not list.

Is Amazon SES cheaper than SendGrid?

Yes, at both scoring volumes: $1.00 against $19.95 for 10,000 emails a month and $10 against $34.95 for 100,000, using SES à la carte and SendGrid Essentials. New SES accounts start on the Essentials plan, which costs $1.60 for 10,000 until you switch.

How long does it take to get out of the Amazon SES sandbox?

You request production access separately in each Region. AWS says its Support team gives an initial response within 24 hours and grants the request in that window when it can; it takes longer if AWS needs more information. Until then you can send only to verified addresses, at most 200 messages per 24 hours.

Does Amazon SES support idempotency keys?

No. The SendEmail API v2 request has no idempotency or client-token field, checked 24 September 2026, so a retry after a timeout can send the email twice. Bird, Brevo, Resend and Telnyx accept an idempotency key on sends.

Which Amazon SES alternative works best with AI coding agents?

Bird and Resend document OAuth sign-in, idempotency keys, signed webhooks with replay checks and hosted MCP servers that send. Telnyx has the same set but no SMTP relay. SES itself has the general AWS MCP Server and an official amazon-ses skill, which AWS's plugins for Claude Code, Codex and Cursor route email tasks to.
