SMTP
Point any SMTP client at Sendfeather — no code required.
Anything that speaks SMTP can send through Sendfeather: WordPress, Postfix, Nodemailer, a scanner on the office network. Create an SMTP user in the dashboard and point the client at the settings below.
| Setting | Value |
|---|---|
| Host | smtp.sendfeather.com |
| Port | 2525 (STARTTLS — recommended) · 587 (STARTTLS) · 465 (TLS) |
| Username | From the SMTP Users page |
| Password | Shown once, at creation |
Create an SMTP user
Open SMTP → Add SMTP user. The password is shown once, so copy it into your client right away. Each user has its own hourly limit and can be disabled without touching the others.
Sending without a password
Servers on a fixed IP can be authorized to send without credentials: open SMTP → IP authentication and add the address or CIDR range. Connections from those addresses are attributed to the project and bounded by the workspace's default rate. Removing the range takes effect from the sender's next message.
WordPress
- 1
Install WP Mail SMTP
The free plugin is enough. Choose the “Other SMTP” mailer.

Set a verified From address
Use an address on a domain you have verified, then press “Send a test email”.
If your host blocks port 587, use 2525 — it exists for exactly that. Every message appears in Activity next to API sends, with the same delivery timeline.
Rate limits
Each SMTP user has an hourly send limit, defaulting to the workspace default. Messages over the limit are refused with a temporary error, so well-behaved clients retry rather than dropping mail.
