Resend is significantly cheaper for teams that need high email volume with smaller lists. Loops gets expensive with large contact lists. Sequenzy offers the best value for SaaS drip-specific needs.

Loops contact-based pricing can get expensive for larger user bases. Resend volume-based pricing is more predictable but requires building drip infrastructure yourself, which has its own development costs.

Frequently asked questions

Can Resend replace Loops for drip campaigns?

Only if your development team can build drip orchestration, user segmentation, and sequence management in code. Resend handles sending, but Loops provides the full drip campaign infrastructure.

Is Loops worth the premium over Resend?

If you need visual drip campaign management without building custom infrastructure, yes. Loops built-in sequence builder, event tracking, and user management save significant development time.
