Send your WordPress newsletter over SMTP, for free
The free version of MailerPress sends your WordPress newsletter through any SMTP server, a better option than PHP Mail.
- Free provider: Custom SMTP is included in MailerPress, no MailerPress Pro needed.
- Any server: your host’s mail server, your company mailbox or an email service’s SMTP relay.
- Everything sent: campaigns, sign-up confirmations, test emails and the free welcome workflow.
- Better than PHP Mail: PHP Mail emails often land in spam or get blocked by hosts.
Included in MailerPress (free). Read the SMTP guide
Works with the SMTP settings you already have
Enter the settings your provider gave you, and the test email shows the cause of any failure.
- Host and port: as given by your host or email provider.
- Encryption: TLS (usually port 587), SSL (usually 465) or None for a local test server.
- Authentication: username and password, or an app password if your provider requires one.
- Test email: shows errors such as Connection refused or Authentication failed, before any campaign.
Bounces read from a mailbox you own
Bounces land in a mailbox you own, and your next campaigns skip those addresses.
- Setting: turn on Enable bounce tracking (IMAP).
- Dedicated mailbox: for example [email protected], used as the return path of your emails.
- Every 12 hours: MailerPress reads the mailbox and gives bounced contacts the Bounced status.
- Limit: if your SMTP provider replaces the return path, bounces cannot be detected this way.
A pace below your host’s limits
Many hosts cap emails per hour, so pick a sending profile that stays under your limit.
- Where: MailerPress > Settings > Sending frequency.
- Gmail SMTP and free providers: 25 emails every 5 minutes, 300 an hour.
- Balanced: 50 emails every 5 minutes, 600 an hour.
- Fastest profile: 100 emails every 3 minutes, 2,000 an hour.
- Manual mode: match your provider’s exact limit.
Set it up
No MailerPress Pro needed: get these details from your host or email provider.
- Server name: the SMTP host of your host or email provider.
- Port and encryption: for example port 587 with TLS.
- Login: SMTP username and password, if authentication is required.
