Which should you choose?

Choose Loops if

You want unlimited contacts rather than contact-count pricing
You need an SMTP relay, inbound email, or webhook infrastructure

Excellent design and editor polish — genuinely pleasant to use
Loops and sequences aimed squarely at SaaS lifecycle email
A simple mental model that non-technical teammates pick up quickly

Feature comparison

Feature and pricing comparison between Unitpost and Loops
Capability	Unitpost	Loops
Transactional email	First-class: idempotency keys, batch sends, scheduling, cancel and reschedule, delivery events per message	Supported, but the product centres on marketing sequences
Contact pricing	Unlimited contacts on paid plans	Priced by contact count
Marketing sequences and automations	Campaigns ship today; automations are behind a flag and not launched	Loops and sequences are the core product
Editor polish	Hybrid visual and code editor over one document	Widely considered best-in-class
SMTP relay	Offered	Not offered
Inbound email	Receiving with a read API for messages and attachments	Not offered
Idempotency keys on send	Idempotency-Key on sends, 24-hour dedupe window	—
Webhook secret rotation without dropped deliveries	svix-compatible HMAC-SHA256 with a 24-hour dual-signing rotation grace	Rotation replaces the secret immediately
Hybrid template editing	Visual drag-and-drop and React/TSX code mode over one shared document — the same @unitpost/email library renders both	Varies
One-key import from Loops	Migration Assistant moves contacts, segments, topics, templates, domains, suppressions, and webhooks in about 4 minutes with a read-only key	n/a

How do I migrate from Loops?

Paste a read-only Loops API key into the Migration Assistant and it previews everything that would carry over — contacts, segments, topics, templates, domains, suppressions, and webhooks. Nothing is written until you accept, and Loops keeps sending the whole time, so there is no downtime. It takes about four minutes.

Two things do not carry over: sending domains must re-verify with freshly generated DKIM keys, and webhook signing secrets are regenerated. Dynamic segments import as a static snapshot of their members.

Frequently asked questions

Is Unitpost a Loops alternative?

For the email-sending half, yes, and the Migration Assistant imports from Loops directly. The honest caveat is automations: Loops' sequences are its core product, and ours are still behind a feature flag. If lifecycle sequences are the reason you use Loops, we are not a replacement yet.

Which is better for a SaaS product?

It depends which email matters more. If your volume is lifecycle and marketing sequences, Loops is purpose-built for that and the editor is better than ours. If you also send receipts, password resets, and alerts — and want idempotency, per-message delivery events, signed webhooks, and an SMTP relay — those are first-class here and secondary there.
