Unable to Connect to SMTP IMAP

title: Unable to Connect to SMTP/IMAP
description: Troubleshoot SMTP/IMAP connection failures and invalid credential errors in SalesBlink.

Overview

If you see a connection failed or credentials are invalid error while connecting your SMTP/IMAP email sender in SalesBlink, the issue is usually related to incorrect credentials or provider-side connection settings.

Solution

Double-check that your credentials are correct. Make sure you are entering the right email address, password, SMTP host, SMTP port, IMAP host, and IMAP port.

If your provider uses an app-specific password, use that instead of your regular account password.

You can also test your credentials with these third-party tools before adding them to SalesBlink:

SMTP Test: https://www.gmass.co/smtp-test
IMAP Test: https://pingability.com/mailtest.jsp
