More about SMTP2GO

SMTP2GO for your WordPress newsletter

Send your WordPress newsletter through SMTP2GO with an API key, with no SMTP port or password to set up.

  • API, not SMTP: despite the name, MailerPress connects through the SMTP2GO API.
  • Primary provider: SMTP2GO also delivers automation emails, sign-up confirmations and test emails.
  • Verified sender: emails leave from a sender you verified in SMTP2GO.

Requires MailerPress Pro.

Bounces, spam reports and rejects off your list

Your next campaigns skip addresses that fail or complain, as soon as SMTP2GO reports them.

  • In MailerPress: turn on Enable bounce tracking.
  • In SMTP2GO: add the MailerPress URL with the bounce, spam and reject events.
  • Bounced status: given for bounce, spam, reject and failed notifications.

Requires MailerPress Pro.

Only genuine notifications are applied

MailerPress checks each bounce notification before it changes a contact, with or without a signing secret.

  • Signing secret: if SMTP2GO gives you one, paste it in Webhook signing secret.
  • With a secret: notifications without a valid signature are rejected.
  • Without a secret: bounces apply only to addresses MailerPress emailed through SMTP2GO in the last 30 days.

Requires MailerPress Pro.

A sending pace for your SMTP2GO plan

Pick the SMTP2GO profile that matches your plan, from the free plan up to 6,000 emails an hour.

  • Free plan (1,000 emails a month): 50 emails every 5 minutes.
  • Balanced: 100 emails every 2 minutes, 3,000 an hour.
  • Faster profile: 200 emails every 2 minutes, 6,000 an hour.
  • Pace, not quota: stay within your plan’s monthly allowance.

Requires MailerPress Pro. Set it in MailerPress > Settings > Sending frequency.
