How do I upload emails to my cold email tool?
SMTP mailboxes
We integrate with all tools that allow connection only via IMAP and SMTP details of mailboxes.
Simply click “export all to csv” on top-right of your maildoso dashboard in the Email-Accounts page. Click the format and you can connect to any tool via IMAP/SMTP method,
If your tool is not listed, select the format “other” and you can change the column names to your tool’s need or sample csv.
If your tool does not support bulk upload of csv, you need to manually enter IMAP and SMTP details in your tool.

To connect your mailboxes to a sequencer, you first need to link the sequencer to Maildoso.
Click on the profile icon in the upper right corner and go to the settings page (https://app.maildoso.com/settings/general), then click on "Sequencer."
Alternatively, you can go directly to the page using this link: https://app.maildoso.com/settings/sequencers
In the window that opens, select your preferred sequencer, click "Configure," and fill in all the required fields.
2. Connecting Mailboxes
Next, go to the Email accounts section (https://app.maildoso.com/accounts), select your Google Workspace mailboxes (you can use the "Provider" filter), click "Add to sequencer," and then choose the desired tool.
Mailboxes will be connected within 2 hours (in some cases, provider-side delays can take up to 24 hours).
