Frequently asked

Is Resend cheaper than Postmark?

Resend's free tier (3,000 emails/month) is more generous than Postmark's, but Postmark has a longer track record on inbox placement. For transactional volume above 100k/mo prices converge.

What's the best email API for indie founders?

Resend has the cleanest developer UX and a generous free tier; Postmark wins on raw deliverability metrics; Loops is purpose-built for product/marketing email rather than transactional. Compare each product page.

How much does Loops cost for a small SaaS?

Loops bundles transactional and product email with simple per-contact pricing. Free tier covers early-stage usage; paid tiers start lower than most marketing email tools. Live pricing on the Loops product page.

Does Postmark separate marketing from transactional?

Yes — Postmark separates streams so a marketing-email IP issue can't poison your transactional deliverability. This is a key reason for picking Postmark over generic SMTP.
