Source: https://reloop.sh/blog/best-aws-ses-alternatives Published: 2026-10-25 **Amazon SES is the cheapest way to send email from a server, and that's exactly why teams outgrow it.** At $0.10 per 1,000 emails nothing hosted beats it on the line item. But SES is a sending pipe, not a product. Before your first password reset reaches a real user, you request production access out of the sandbox, wire bounce and complaint events through SNS or EventBridge, build a suppression store, and find somewhere to keep delivery logs that support can actually search. **The short version:** if you want SES-like prices with the product already built, **Reloop** is the closest swap ($10 for 50k, $20 for 100k, open source). If your app lives on Cloudflare Workers, **Cloudflare Email Service** is the native choice. If you only send transactional mail and want prepaid credits, look at **ZeptoMail**. If deliverability is your only metric, **Postmark**. We build Reloop, so weigh our entry accordingly. Every other provider's facts come from our researched head-to-head posts, linked in each section, and each section says where that provider beats us. --- ## Why teams look for an Amazon SES alternative SES is a great piece of infrastructure. The reasons people leave are almost always about what's missing around it: - **The sandbox.** New accounts can only send to verified addresses until AWS approves production access, and requests are sometimes denied or need a second round. - **Glue code.** Bounces, complaints and deliveries arrive through a configuration set and SNS, EventBridge or Firehose. You build the consumer, the storage and the suppression logic yourself. - **No logs or dashboard.** "Did the reset email arrive?" means digging through CloudWatch or an internal tool you had to write. - **Templates for engineers only.** Templates are API-managed, so non-engineers can't edit copy without a deploy. - **No marketing, no real inbound.** Newsletters need another tool, and inbound mail lands in S3, SNS or Lambda as raw messages. - **Account risk.** AWS reviews accounts whose bounce or complaint rates stay high and can pause sending, so you need your own monitoring. None of that matters if you have a platform team and send millions of emails a month. For everyone else, the engineering time costs more than the per-email savings. Full breakdown: [Reloop vs Amazon SES](/blog/reloop-vs-aws-ses). --- ## Top picks at a glance | Category | Pick | Why | |---|---|---| | **Best overall SES alternative** | Reloop | Full platform at $10 for 50k, open source, self-hostable | | **Best for Cloudflare Workers apps** | Cloudflare Email Service | Native binding, $0.35 per 1k after 3k included | | **Best prepaid, transactional-only** | ZeptoMail | Credits with no monthly fee | | **Best for deliverability focus** | Postmark | Transactional-only track record, message streams | | **Best developer experience** | Resend | Clean API and React Email | | **Best for email validation and routing** | Mailgun | Inbound routes, validation add-on | | **Best for enterprise procurement** | SendGrid | Twilio contracts, subusers, IP pools | | **Best self-hosted MTA** | Postal | MIT-licensed mail server you run yourself | --- ## The comparison table | | Amazon SES | Reloop | Cloudflare | ZeptoMail | Postmark | Resend | Mailgun | SendGrid | |---|---|---|---|---|---|---|---|---| | **Free** | $200 AWS credits, 6 months | 6,000 / mo (200 / day) | Own verified addresses only | First credit (10k emails) | 100 / mo | 3,000 / mo (100 / day) | 100 / day, trial | 100 / day, 60-day trial | | **~50k / mo** | ~$5 | **$10** | about $21 | about $12.50 | $87 | $20 | $35 | $19.95 | | **~100k / mo** | ~$10 | **$20** | about $39 | about $25 | $177 | $35 | $90 | $34.95 | | **Delivery events** | SNS / EventBridge, you wire it up | Signed HTTP webhooks | Cloudflare Queues | Webhooks | Webhooks | Webhooks | Webhooks | Webhooks | | **Inbound** | Receipt rules to S3 / SNS / Lambda | Mailboxes, API, MCP, IMAP | Email Routing | Not offered | Webhook (Pro and up) | Webhook | Inbound routes | Inbound Parse | | **Marketing** | No | Campaigns + automations | No | Not allowed | Broadcast streams | Broadcasts | Limited | Separate plans | | **Open source / self-host** | No | Yes (Apache 2.0) | No | No | No | No | No | No | Prices are taken from each provider's pricing page as covered in our head-to-head posts. The Cloudflare figures include the $5 Workers Paid minimum; the ZeptoMail figures use the widely listed $2.50 per 10k credit, which varies by region. Postmark at these volumes is list price plus overage; Mailgun at 100k is its $90 Scale plan. SES figures are send-only, before $0.12 per GB of outbound data. --- ## 1. Reloop: best overall Amazon SES alternative [Reloop](/) is open-source email infrastructure: a transactional API, SMTP relay, templates, logs, signed webhooks, inbound mailboxes, contacts, campaigns and event automations in one product. It runs its own MTA (KumoMTA) rather than reselling SES, and **Reloop Cloud runs on Hetzner, a German hosting company, with EU data centers**. **Pricing:** Free for 6,000 emails a month (200 a day). Pro is $10 for 50,000, Growth is $20 for 100,000 with a dedicated IP included, and extra mail is $0.50 per 1,000. Or prepay credits at $0.50 per 1,000, valid for 6 months. Self-hosting under Apache 2.0 has no per-email fee at all. ```typescript const reloop = new Reloop({ apiKey: process.env.RELOOP_API_KEY! }); const { response, emailError } = await reloop.mail.send({ from: "Acme ", to: "user@example.com", subject: "Welcome", html: "

Thanks for signing up.

", }); ``` **Strengths** - **Everything you'd build around SES is already there**: suppression, searchable logs, webhooks signed with `Reloop-Signature`, and templates with `{{{variables}}}`. - No sandbox. Verify your domain and send. - Inbound mail lands in real mailboxes with threads, readable over the API, the MCP server or IMAP (3, 5 and 10 hosted inboxes on Free, Pro and Growth). - Campaigns and event automations share one suppression list with transactional mail. - Open source, so you can move to your own servers and keep the same API. **Weaknesses** - **SES is cheaper per email at high volume.** At a million emails a month SES is about $100 sending-only; Reloop is $470 hosted. Self-hosting closes that gap, but then you run it. - No IAM integration. You authenticate with an API key, not AWS roles. **Best for:** teams that picked SES for the price and are tired of maintaining the glue.

Cloudflare Email Service: best for Workers apps Cloudflare added outbound sending to its Email Service in a public beta in April 2026. From a Worker it's one binding and one `send()` call, with no API key to store. **Pricing:** sending to any recipient requires Workers Paid ($5 a month minimum), which includes 3,000 emails, then $0.35 per 1,000. The free plan only sends to addresses you've verified in your own account. **Strengths** - Native Workers binding; errors come back with clear codes such as `E_SENDER_NOT_VERIFIED`. - Cheaper than Reloop above roughly 200k emails a month. - Inbound via Email Routing, which is generally available. **Weaknesses** - Sending is still in public beta. - Your domain must use Cloudflare DNS. - Transactional only; templates and dedicated IPs aren't documented. Events go to Cloudflare Queues, not HTTP webhooks. **Best for:** apps that already live on Workers and only send transactional mail. Full comparison: [Reloop vs Cloudflare Email Service](/blog/reloop-vs-cloudflare-email). --- ## 3. ZeptoMail: best prepaid, transactional-only option ZeptoMail from Zoho, now part of Zoho CPaaS, sells email on prepaid credits: one credit sends 10,000 emails, the first one is free, and credits last 6 months. **Pricing:** about $2.50 per credit (varies by region), so roughly $12.50 for 50,000 and $25 for 100,000 emails. **Strengths** - No monthly fee, and cheaper than Reloop above roughly 150,000 emails a month. - Mail Agents keep products or environments apart, each with its own tokens, domains and stats. - SMTP relay and REST API, plus SMS, WhatsApp and voice in the wider Zoho CPaaS. **Weaknesses** - Marketing mail isn't allowed; accounts that keep sending it get blocked. - No inbound mailboxes. - Credits expire after 6 months. **Best for:** price-sensitive teams sending only transactional mail. Full comparison: [Reloop vs ZeptoMail](/blog/reloop-vs-zeptomail). --- ## 4. Postmark: best for deliverability focus Postmark has built its reputation on fast, transactional-first delivery, with separate message streams to keep transactional and broadcast traffic apart. **Pricing:** free for 100 emails a month. Basic starts at $15 for 10,000, with overage at $1.80 per 1,000 ($1.30 on Pro). That's about $87 at 50,000 and $177 at 100,000 on Basic list price; use Postmark's calculator for an exact tier. **Strengths:** long transactional-only track record, message streams, excellent docs and support. **Weaknesses:** far more expensive than SES or Reloop at volume; dedicated IPs are $50 a month from 300k emails; inbound is a webhook on Pro and up; no self-hosting. **Best for:** teams where every millisecond of reset-email delivery matters and budget doesn't. Full comparison: [Reloop vs Postmark](/blog/reloop-vs-postmark). --- ## 5. Resend: best developer experience Resend set the bar for a modern email API and created React Email. Worth knowing for SES refugees: **Resend sends through Amazon SES** under the hood, with its own product layer on top. **Pricing:** free for 3,000 a month (100 a day), $20 for 50,000, $35 for 100,000, overage $0.90 per 1,000. **Strengths:** clean API and SDKs, React Email, a large ecosystem of examples, broadcasts for simple marketing. **Weaknesses:** $35 at 100k vs about $10 on SES; a dedicated IP needs the $90 Scale plan plus a $30/mo add-on; inbound is a webhook per message; hosted-only. **Best for:** teams that want the most polished hosted API and stay under 50k emails a month. Full comparison: [Reloop vs Resend](/blog/reloop-vs-resend). --- ## 6. Mailgun: best for email validation and routing Mailgun is a long-standing developer email API with inbound routes (match by pattern, then forward or post to a webhook) and email validation as a paid add-on. **Pricing:** 100 a day on a trial. Basic is $15 for 10,000; Foundation is $35 for 50,000; 100,000 is about $100 with overage from $1.30 per 1,000. **Strengths:** mature API, inbound routes, Handlebars templates, validation. **Weaknesses:** expensive at 100k compared with SES or Reloop; dedicated IPs and validation cost extra; marketing is a separate Sinch product. **Best for:** teams that need validation and inbound routing from one vendor. Full comparison: [Reloop vs Mailgun](/blog/reloop-vs-mailgun). --- ## 7. SendGrid: best for enterprise procurement SendGrid, part of Twilio, is the default enterprise choice, with subusers, IP pools and a mature compliance program. **Pricing:** a 60-day trial at 100 a day. Essentials is $19.95 for 50,000 and $34.95 for 100,000. Dedicated IPs, subusers and SSO start on Pro at $89.95. **Strengths:** full Handlebars templates, enterprise contracts, Marketing Campaigns as an add-on. **Weaknesses:** marketing is priced separately; no permanent free tier; the features most SES users want (dedicated IP) need Pro. **Best for:** companies that need a Twilio contract. Full comparison: [Reloop vs SendGrid](/blog/reloop-vs-sendgrid). --- ## 8. Postal: best self-hosted mail server If you're leaving SES because you'd rather own the sending path entirely, [Postal](https://github.com/postalserver/postal) is a mature, MIT-licensed mail server with an HTTP API, SMTP, webhooks and IP pools with routing rules. There's no hosted version. **Pricing:** free; you pay for the server. Its minimum is 2 CPU cores, 4 GB RAM and 25 GB disk, with MariaDB 10.6 or newer. **Strengths:** lightweight, proven MTA; multiple IP pools; no per-email fees. **Weaknesses:** no stored templates, contacts, campaigns or inbound mailboxes; you own IP reputation, warm-up and uptime. **Best for:** teams that want a pure, self-run MTA. Reloop is also self-hostable if you want the full platform on your own servers. Full comparison: [Reloop vs Postal](/blog/reloop-vs-postal). --- ## How to choose - **"We chose SES for the price but spend too much time on glue code."** Reloop. Same idea of cheap sending, with logs, suppression and webhooks built in. - **"We send millions of emails a month and have a platform team."** Stay on SES, or self-host Reloop to keep zero per-email fees with a product on top. - **"Our whole app runs on Cloudflare Workers."** Cloudflare Email Service. - **"We only send transactional mail and want the lowest bill."** ZeptoMail, or Reloop below about 150k a month. - **"Deliverability is the only thing that matters."** Postmark. - **"We need inbound mail as real inboxes, for support or AI agents."** Reloop. - **"We want to run our own mail server."** Postal for a pure MTA, Reloop for the full platform. --- ## Migrating off Amazon SES The steps are the same whichever provider you pick: 1. **Verify your domain** with the new provider. Add its DKIM record and merge its include into your existing SPF record; never publish a second SPF record. Keep DMARC in place. Our [SPF, DKIM and DMARC guide](/blog/spf-dkim-dmarc-setup-guide) covers it. 2. **Export your suppression list** from SES's account-level list and your own store, and import it so you don't email addresses that bounced or complained. 3. **Swap the send call.** Replace `SendEmailCommand` with the new SDK. On Reloop, change `{{variable}}` placeholders to `{{{variable}}}`. 4. **Replace the SNS or EventBridge consumer** with a webhook handler. On Reloop, verify the `Reloop-Signature` header. 5. **Ramp traffic** from 10% to 100% over one to two weeks, watching bounce and complaint rates. 6. **Tear down** the configuration sets, SNS topics and Lambda functions you no longer need. --- ## FAQ Per email, nothing hosted beats SES's $0.10 per 1,000. Among full platforms, Reloop is the cheapest at $10 for 50,000 and $20 for 100,000. ZeptoMail and Cloudflare get cheaper than Reloop above roughly 150,000 and 200,000 emails a month. Self-hosting Reloop or Postal removes the per-email fee entirely. Yes. Reloop is open source under Apache 2.0 and includes the API, dashboard, inbound mailboxes and campaigns. Postal is an MIT-licensed mail server focused on sending. Both can run on your own servers. Yes. Resend sends through Amazon SES and adds its own API, dashboard and features on top. Reloop runs its own MTA (KumoMTA) instead. No. The sandbox is an AWS process. On Reloop you verify your domain and can send to real users right away, within the free tier's 200-a-day cap. Yes. Every provider here except Cloudflare's Workers binding offers SMTP; Cloudflare offers SMTP in beta. Reloop's relay is `smtp.reloop.sh`, with your API key as both username and password.
