Smarter Mail

First, try

IMAP: securemail.dealerspike.com Port: 993

SMTP: securemail.dealerspike.com Port: 465

If that doesn't work, try

IMAP: mail.dealerspike.com Port: 143

SMTP: mail.dealerspike.com Port: 587

And if that still doesn't work ensure the username and password are correct. If you are still experiencing issues, send a help ticket to emailsupport@dealerspike.com
