Datananas Outbound allows you to connect to your Gandi account.
For this purpose:
1. Go to your Settings > Email
2. Click on Gandi
3. In the field that appears, complete all Email, IMAP and SMTP host, port, username and password
4. Click on Connect
If the synchronization doesn't work, select Other, and configure the advanced connection (cf. article Synchronize my mailbox with SMTP/IMAP )
Gandi is no longer allowing its users to send emails through Datananas that include our shared tracking domain (dtns.me). If you wish to send emails sequences and that your provider is Gandi, we strongly advise you to create a custom tracking domain (this is also strongly advised if you wish to highly improve your deliverability).
Also, Gandi has very strict policy about commercial emails :
make sur you send high-quality content (clear value proposition sent to relevant prospects for instance)
make sure to always have an unsubscribe link at the end of your emails (I add an unsubscribe link)
make sure you follow CAN-SPAM rules (I check CAN-SPAM rules)
