Loops
Product and marketing email for SaaS, without the enterprise UI.
NOT REALLY
why this verdict
Keep paying — OpenAI has not replaced it
OpenAI's version overlaps, but does not finish the email job, so this one still earns its $49/mo.
- A named launch, not a vibe named, unlinked
- AI drafting made email copy cheap but not deliverable. OpenAI, March 1, 2025 — no announcement link recorded yet.
- How much of the job it covers not the job editorial call
- Parts of it. The job still needs the tool to get finished.
- Is there a free way to do it? yes
- 2 of 3 listed replacements have a usable free tier: Resend and Plunk.
- What the call is worth $588/yr
- $49/mo at the entry paid tier — $588 a year per seat.

The backstory
Loops spread through indie SaaS on X by being the first email tool that looked built this decade: an API for transactional sends, a visual builder for lifecycle campaigns, none of the legacy complexity. Drafting copy is what AI took; routing, sending and staying out of spam is what Loops sells.
