Postwing

is an email delivery service with SMTP support. You can use it as your own SMTP server so that emails to subscribers are sent from your address instead of the default one. The setup works the same way for a status page and a release page.
  • On a status page the setting is marked with a
    Premium
    badge — a paid plan is required.
  • On a release page the form is visible to the team owner only.
1
Create a token in Postwing
  • Sign in to your Postwing dashboard.
  • Open the token management page and create a new token. You choose the login yourself; the password is generated automatically.
  • Save the password right away: it is shown only once and cannot be recovered. If you lose it, delete the token and create a new one.
2
Set up the sender domain
So that your emails pass SPF checks and do not land in spam, the domain you send from must be delegated to Postwing. Follow the guide. The sender address must be on that domain.

Open the email settings
  • Status page:
    Settings
    Notifications
    , the
    Email Settings
    section. Turn on the
    Send from a custom email address
    switch.
  • Release page:
    Settings
    Notifications
    , the
    Email setup
    section. Turn on the
    Send emails from your own address
    switch.
  • Once the switch is on, the SMTP fields appear.

  • Sender
    on the status page, or
    From
    on the release page — the address emails are sent from, in the format
    System Status <status@yourcompany.com>
    . Use the domain you configured in step 2.
  • SMTP Server
    smtp.postwing.app
    .
  • Port
    587
    (STARTTLS). If your hosting provider blocks standard mail ports, use
    8587
    .
  • Username
    and
    Password
    — the token login and password from step 1.
  • Use TLS
    — must be enabled.
  • Save the changes.
The Postwing documentation recommends port
465
with SSL/TLS as the default option. Our form only has the
Use TLS
flag, which corresponds to STARTTLS, so enter port
587
or
8587
.

Done! Subscriber emails are now delivered through Postwing from your own address 📮
