5 Cheap Resend Alternatives in 2026

I get a version of this question a few times a month: "Resend's a good product, but the pricing math doesn't work for us — what should we look at instead?" Usually it's a team sending somewhere between 3,000 and 50,000 emails a month, hitting Resend's $20 paid floor and paying the same as someone sending ten times more. This post is the answer I send back, with five alternatives ranked by price-to-feature ratio.

One disclosure up front: I run PostStack, which is on this list. I've put it where I think it belongs and given the trade-offs honestly. The other four are providers I've used personally or evaluated for migration paths.

Why people leave Resend

• The $20 floor. No paid tier below $20/month. If you send 4,000 emails you pay the same as someone sending 49,999.
• No EU data residency. Resend is a US company on US infrastructure. For European buyers with a CLOUD Act-aware DPO, that's a non-starter.
• Missing features. No IMAP mailboxes for support@yourdomain.com, no DMARC aggregate report parsing, no visual email builder.
• Dedicated IP only at enterprise. If your reputation profile needs an IP today, Resend can't sell you one without a sales call.

1. PostStack — direct Resend alternative, EU-hosted

Price: free for 3,000/month, €5/mo for 10,000, €15/mo for 50,000, €30/mo for 100,000.

PostStack matches Resend's API shape and webhook event vocabulary deliberately — the migration is essentially renaming the SDK and updating one env var. What you get on top: 18-72% cheaper paid tiers (after FX), EU-only infrastructure (Helsinki, Finland), IMAP/POP3 mailboxes, a visual email builder, parsed DMARC aggregate reports, and multi-step workflow automation in the base product.

Best for: teams that liked Resend's developer experience but want the price band below $20 and EU data residency.

2. Amazon SES — cheapest raw infrastructure

Price: $0.10 per 1,000 emails (~$1 for 10,000). New AWS accounts get 3,000 messages/month free for the first 12 months.

SES wins on cost-per-email if you already live in AWS and have someone to wire it up. The trade-offs are real: no useful dashboard, no webhooks until you stand up SNS + Lambda yourself, no templates worth the name, and you own your sending reputation including IP warmup. It's infrastructure, not a product.

Best for: AWS-native teams with an ops engineer who's happy building the missing pieces.

3. Mailgun — API-first, scales well

Price: Basic $15/mo (10K), Foundation $35/mo (50K), Scale $90/mo (100K). Free tier is 100/day.

Mailgun pre-dates Resend and has been the reliable backend choice for high-volume transactional senders for years. Strong inbound routing, decent docs, no real broadcast or marketing tooling. At low volumes it's not dramatically cheaper than Resend, but it scales better past a million sends/month.

Best for: high-volume API-only senders with no broadcast needs.

4. SendGrid — the legacy incumbent

Price: 60-day trial (100/day), then paid from $19.95/mo Essentials (50K), $89.95/mo Pro (100K).

Not actually cheaper than Resend at most tiers, but worth knowing about because it integrates with almost every legacy platform and is bundled with Twilio. The v3 API feels its age, and dedicated IPs, SSO, and advanced stats are separate add-ons.

Best for: teams already using Twilio for SMS, or stuck on a legacy platform that only supports SendGrid.

5. Brevo (formerly Sendinblue) — marketing-first

Price: free for 300/day (~9,000/month), paid plans starting low for larger volumes. Pricing varies — check the current page before committing.

Brevo's transactional API is a secondary product to its marketing and CRM stack. The dashboard is built for marketing users rather than developers, and the API surface is shallower than Resend or PostStack. EU-hosted (French company), which matters for compliance.

Best for: small businesses sending both marketing campaigns and lighter transactional traffic.

Honourable mentions

Postmark ($15/mo for 10,000) isn't dramatically cheaper than Resend at every tier, but holds the strongest deliverability reputation in transactional email. Mailtrap is worth knowing if you want a sandbox for dev/staging mail alongside production sending.

The recommendation

If you're leaving Resend mainly because of the price floor and want a like-for-like replacement with the same DX — that's PostStack. If you're leaving because you have AWS expertise and want absolute lowest cost — that's Amazon SES, with the operational tax that goes with it. Most product teams I talk to land on the first answer.
