Plume email composer · live mockup
Self-hosted email marketing that runs on a $6 VPS. One Docker compose file, one Postgres, one worker. Unlimited subscribers, unlimited campaigns, SMTP your way — and none of the send-tier "upgrades" that make every email platform feel like a telecoms bill.
docker compose up -d and you're running. API, worker, Postgres, Redis — five containers, forty megabytes each, one binary to rebuild.
No per-contact pricing. 10k or 1M subscribers, same price. Plume bills the VPS; the VPS bills itself by bandwidth.
Postmark, SES, Resend, SendGrid, or a plain Postfix on a second box. Plume treats SMTP as a driver, not a lock-in.
No query-builder UI. You write a read-only SQL against your subscriber schema, it saves as a segment. Powerful, boring, fast.
Opens, clicks, unsubs, bounces — with actual privacy math. No 1-pixel tracking by default; the user opts in.
Every table, every campaign, every open — exportable as CSV or JSON via API. Your data stays your data.
Yes, on a $20 VPS (2 vCPU, 4GB RAM). We tested to 2.1M and hit the SMTP provider rate limit long before we hit Postgres. See the operator's manual for sizing.
No. Plume sends through your SMTP — Postmark, SES, Resend, or self-hosted Postfix. This is on purpose: the SMTP market is competitive and priced well; we don't add a margin on top.
Not yet. We may offer one in 2027. For now, self-hosted only.
Unsubscribe headers, one-click unsubscribe, IP logging (off by default), data-retention knobs — all built in. The operator's manual walks you through the compliance checklist.
Exactly what was on the tin. No upsells, no tier gates, no "contact us for pricing" once I was in. Shipped in an afternoon and the docs were readable by a human.
I've bought half the catalogue at this point. The voice is consistent, the prices are honest, and the updates actually land. It's what indie shipping should look like.
Did what the page said it would do. Knocked off half a star because I wish there was a Windows native build — I'm on WSL and it works but feels like a workaround. Support replied to me in four hours.
I bought it at 11pm, downloaded it at 11:01pm, had it running at midnight. That's the whole review. Email went to a person who answered the next morning.
The amount of thought in the copy alone makes this worth the price. And that's before you get to the actual product. Rare to see this level of care at indie prices.
Swapped out my previous tool for this one last sprint. Fewer features, honestly — but the ones that are here are the ones I actually use. Don't miss the rest.
