Guide on how to connect accounts with custom SMTP and IMAP

Updated this week

You can link Sendgrid, Mailgun, Amazon SES, and other SMTP providers to Instantly by combining SMTP from these services with IMAP from your email provider.

To establish this connection, you'll require an IMAP inbox to intergrate SendGrid, Mailgun, or other services with Instantly, enabling support for all features.

Many of our users opt to use their Gmail account as the IMAP target for receiving emails while utilizing SendGrid or Mailgum for SMTP to send emails.

Note: Connecting your Outlook accounts through the IMAP/SMTP method is not feasible, as Outlook/Microsoft accounts can only be connected via the oAuth Microsoft connector.

If you're looking to link Sendgrid with Google IMAP for seamless email integration, follow these straightforward steps:

  1. Generate an App Password in Your Google Account
    Begin by generating an app-specific password within your Google account settings. This password will be used to authenticate your connection between Sendgrid and Google IMAP.

    Check this guidance to generate your Google App Password.

  3. Choose Single Account Configuration
