Frequently Asked Questions
Can Resend be used for drip email campaigns?
Not out of the box. Resend is an email API for sending, not a marketing automation platform. You would need to build all drip logic (delays, conditions, sequences) in your own application code.
Is Loops or Resend better for SaaS?
It depends on the use case. For marketing drip campaigns, Loops is far better. For transactional email delivery with React templates, Resend is superior. Many teams use both.
Can I use Loops and Resend together?
Yes, some teams use Loops for marketing drip campaigns and Resend for transactional emails like password resets and receipts. This gives you the best of both.
Which has better developer experience?
Resend has the superior developer experience with its beautifully designed API, React Email support, and multi-language SDKs. Loops is developer-friendly but more focused on its visual UI.
