Upon signing up, Mailsuite adds a branded signature, “Sent with Mailsuite,” which includes an unsubscribe link, to every new email you compose.
You can choose to remove it permanently or just remove it for the current email. Please, ensure you comply with the applicable data protection regulations.
If you choose to remove the signature permanently, you can reactivate it anytime from the Mailsuite settings.
Additionally, you can always include a standalone unsubscribe link in your emails using the option in the Mailtrack menu in the Gmail composer.
