If your sequencer is not one of the supported dashboard integrations, we can review another connection route rather than assuming it cannot work.
IMAP/SMTP connections
Many tools can add a mailbox using its server details, username and password. Sending works through that connection, but you manage warm-up yourself and our warm-up monitoring and troubleshooting are limited.
Contact support to confirm the upload and follow the instructions shown for your inbox group. Keep connection details and CSV exports private.
Allow at least 3 weeks of warm-up before campaigns and follow the assigned daily settings. Do not assume the tool's default limits are suitable.
Other options
If the tool requires a Microsoft sign-in connection, ask support to review vendor compatibility before building an integration. You can also consider a supported sequencer: Instantly, Smartlead, Plusvibe or EmailBison.
A generic email icon instead of a Microsoft logo does not by itself indicate an error. Report actual connection or sending failures with the exact message.
