The 6 Best Resend Alternatives in 2026 (Email APIs I've Shipped With)
Dušan Jovović
Founder of Tolodora. I build and ship software for a living, so I only recommend tools after using them on real work — and I tell you what I actually like and don't.
Resend genuinely made sending email from an app pleasant — clean API, great docs, React email support. I use it and like it. But if you need a different price point, more enterprise features, or a specific deliverability reputation, there are strong alternatives in 2026. I've integrated each of these into real projects, so here's my honest take on the six best Resend alternatives — what I like, the trade-offs, and who each is for.

Best for
Cheapest raw sending, especially on AWS.
Amazon SES provides extremely low-cost, reliable email sending, especially if you're already in AWS. The trade-off is a barebones experience, but the price is hard to beat.

What I like
Email API plus full marketing, SMS and CRM, priced fairly — a lot of value in one platform.
Best for
Teams wanting an API plus marketing suite.
Brevo offers a transactional email API alongside a full marketing, SMS and CRM suite. A good Resend alternative when you want developer email and marketing in one place.
How I'd choose: want rock-solid transactional deliverability and great support? Postmark. Need huge scale and flexibility? SendGrid or Mailgun. Already on AWS and want the cheapest raw sending? Amazon SES. Want email that doubles as marketing automation? Loops or Brevo. For a new app I'd often start with Resend and reach for these as specific needs appear.
