Overview

SMTP is the advanced option for custom email. Use it if you have an existing mail server, or want to send through Google Workspace or Microsoft 365 rather than a dedicated provider like Mailgun or Postmark.
SMTP setup requires more technical knowledge than Mailgun or Postmark. Use it only if you have specific requirements.

​
Required settings

​
Google Workspace setup

  1. Generate an app password: Google Account → Security → 2-Step Verification → App passwords, for “Mail”.
  2. Use smtp.gmail.com, port 587, TLS/STARTTLS, your full Google Workspace email as username, and the app password (not your account password).
  3. Enter these in Vapify’s SMTP fields, click Test Connection, then Save Settings.

​
Security

  • Never use your primary account password
  • Always use app-specific passwords when available
  • Use TLS/SSL encryption (port 587 or 465)
  • Rotate app passwords regularly
