Self-hosted affiliate program on your own Sendy VPS.
Sendy is the bring-your-own-server email platform, buy the license once, host it on your own VPS, send through Amazon SES at near-zero cost. Rekomi respects that posture by treating your Sendy install URL as user-supplied and SSRF-validated.
From paste-API-key to first paid affiliate in 10 minutes.
Paste your Sendy API key into Rekomi. Rekomi runs a test call to verify the key, then pulls your list/audience picker live from Sendy so you pick the right destination.
Affiliates apply via your public landing page or your bulk invite. Approve them manually, auto-approve on a campaign, or import an existing affiliate CSV from Rewardful.
Approved affiliates land in your Sendy list as tagged subscribers within seconds. Rekomi handles idempotency, retries, and per-campaign overrides; you handle the nurture sequence.
The exact Sendy fields Rekomi writes.
No surprise fields, no overwrites of contact data you already have. Empty values are omitted so existing nurture data is preserved.
POST /subscribe(form-encoded) withapi_key,list,email,name,gdpr: true,silent: truesilent: true, skips Sendy's double opt-in (the affiliate already opted in by accepting your program)- List ID is Sendy's encrypted ID (not a plain number; shown in Sendy's Lists page)
- Install URL is brand-supplied, Rekomi's SSRF guard rejects non-HTTPS, IP literals, internal hosts, userinfo, and non-default ports
- Returns plain-text

What Sendy customers actually do with Rekomi.
Cheapest possible affiliate stack at scale
Sendy license ($79 one-time) + your own VPS ($5-20/month) + Amazon SES ($1 per 10k emails) + Rekomi Starter ($49/month) = $50-70/month total for unlimited email volume + unlimited affiliates. Hard to beat at scale.
Data-sovereignty self-hosting
Self-hosted Sendy means your subscriber data lives on YOUR server, in YOUR jurisdiction, behind YOUR firewall. Rekomi pushes contacts via authenticated HTTPS; your Sendy admin retains full control.
Ops-aware founder pairing
If you're running your own VPS for Sendy, you've already opted into ops complexity. Rekomi's managed offering handles the affiliate engine so you don't have to build that yourself too. Best of both: self-hosted email, managed affiliate program.
Rekomi handles Sendy's edge cases so you don't have to.
Every CRM API has quirks. Rekomi's integration code was built and audited against the live Sendydocs, these are the ones you'd otherwise hit yourself.
Sendy's install URL is YOURS, typically `https://yourdomain.com/sendy/`. Rekomi validates the URL: HTTPS only, no IP literals, no internal hosts (localhost, 169.254.*, metadata endpoints), no userinfo, no non-default ports. DNS rebind protection also blocks resolved private IPs.
Sendy returns plain-text responses (`true`, `Already subscribed.`) not JSON. Rekomi parses both as success. Re-syncing an affiliate 50 times returns `Already subscribed.` 50 times, no duplicates, no failures.
Sendy's list IDs in the API are encrypted strings (not the numeric IDs you see in the URL). Rekomi's connect flow takes the encrypted ID from the Sendy Lists page; manual entry, since Sendy has no list-enumeration endpoint scoped to API key alone.
Built for ops-aware founders and self-hosted email enthusiasts running Sendy on their own VPS with Amazon SES. If you've intentionally opted into self-hosting for the cost or sovereignty benefit, Rekomi is the managed counterpart that keeps your affiliate engine off your ops plate.
Common Sendy questions.
Does Sendy have an affiliate program?
Sendy itself doesn't run a customer-referral program, the one-time-license model means there's no recurring revenue to share. Rekomi is the layer that lets you run YOUR affiliate program on YOUR product, using Sendy as the email home.
Will Rekomi work with my self-hosted Sendy install?
Yes, Rekomi's Sendy integration takes your install URL as input. The URL is validated against SSRF rules (HTTPS only, no internal IPs). Your install can be on any public-internet-accessible domain.
What about the Sendy license cost?
Sendy is a one-time $79 license (plus optional add-ons). After that, your ongoing email cost is just AWS SES (~$1 per 10k emails). For high-volume senders, Sendy + Rekomi is the cheapest possible full-stack affiliate marketing setup.
