Drin vs Loops.
Loops built a lovely, product-led email tool for SaaS teams. Drin comes at the same job from the developer's side: an API-first platform that bills for the mail you actually send — not the size of your audience — and does inbound and agents too.
Free sandbox to integrate · Production from $3/month
Loops charges by contacts; Drin charges by volume — and does the developer half too.
Loops is genuinely nice to use. If a marketer owns your lifecycle email and wants a clean UI with product-triggered flows, it's a fair choice.
But per-contact pricing punishes a growing list even when you rarely mail it, there's a 'Powered by Loops' footer on free, and it isn't built for inbound or agents. Drin bills by volume with unlimited contacts on the marketing lane, never brands your mail, and adds real inboxes plus an MCP surface — starting at $3/mo versus $49.
Line by line, Drin vs Loops.
The whole surface, side by side — no asterisks. Where Loops is strong, it says so.

The three that decide it.
A 200k-person list you email monthly costs Loops a fortune. Drin bills the volume you send, with unlimited contacts on the marketing lane.
No 'Powered by' footer, ever — even on the smallest plan. Your mail looks like yours from day one.
Loops sends; Drin also receives. Real inboxes parsed to JSON, plus an MCP server so agents can run the whole loop.
What you actually pay.
The models differ: Loops charges by how many contacts you store; Drin charges by how much mail you send. Big list, occasional sends → Drin is far cheaper. Small list, constant sends → compare directly.
| Price point | DrinVolume-only | Loops |
|---|---|---|
| Free / sandbox | 100 test msgs/mo | 1,000 contacts (branded) |
| Entry (production) | $3/mo — 5k sends | $49/mo — 5,000 contacts |
| Pricing basis | Email volume sent | Subscribed contacts |
| Unlimited contacts | Yes (marketing lane) | No |
| Inbound + agents | Included | Not offered |

What Loops does well
Loops is one of the most pleasant marketing-email tools for SaaS — the interface is clean, the product-triggered flows are well designed, and it avoids the bloat of legacy tools like Mailchimp or HubSpot. If a non-technical marketer owns lifecycle email and lives in a UI, they'll enjoy it. Drin is a different shape: developer-first, API-and-agent-native, and priced by volume — better when engineering owns email and the list is large relative to how often you mail it.

Asked about Loops.
I have a big list I rarely email — who's cheaper?+
Drin, usually by a lot. Loops bills by stored contacts; Drin bills by messages sent. A large, low-frequency list is exactly where per-contact pricing hurts.
Does Drin have a marketing UI?+
Yes — campaigns, multi-step automations, lists/segments and a hosted preference page. It's developer-first, but marketers can run it from the dashboard.
Will my emails say 'Powered by Drin'?+
Never. There's no brand footer on any plan, including the sandbox.
Can Drin trigger flows from inbound mail?+
Yes. An inbound reply can start an automation — a winback pause, a handoff, a follow-up. Loops has no inbound.
