Last checked 2026-08-02 against Resend's public pricing.
Yes, by design: MailBlastr prices at roughly 0.7× Resend. The 50,000-email tier costs about 30% less than Resend Pro at the same volume, and the gap holds at 100,000 emails and above. Both have a 3,000-email free tier.
You can render React Email (or MJML, or any templating pipeline) to HTML and send the result through the MailBlastr API — the API accepts full HTML bodies. What MailBlastr does not do is maintain the React Email library itself; that is a genuine Resend strength.
Yes — campaigns, audiences, segments, topics, A/B tests, polls, and visual automations are included in every MailBlastr plan, including Free. On Resend, marketing sends go through Broadcasts with contact limits by plan and no automation journeys.
The concepts map one-to-one: API keys, verified domains, a POST /emails endpoint, batch sending, and signed webhooks. Most teams swap the SDK call and re-point webhook URLs in under an hour; DNS verification of your domain is the only waiting step.
Yes — 3,000 emails/month capped at 100/day on one domain. MailBlastr’s free tier matches the 3,000/100-per-day volume and includes 1,000 contacts plus campaigns and automations, so you can trial marketing sends too.
