To change a mailbox's display name, contact support with the mailbox name and the new first/last name — our team updates it on the backend (this does not require recreating the mailbox or restarting warmup). After the update, remove the mailbox from your sequencer and re-add it using a freshly exported CSV so the new name syncs. If you send through a sequencer, also confirm the sender name configured there, since the sequencer can override what recipients see. For where to export that CSV from, see How can I access mailbox credentials in Maildoso?

Profile pictures (sender avatars) are available on Google Workspace mailboxes only. We don't add them on SMTP mailboxes, where a profile picture makes the mailbox easier to footprint and flag by spam filters (see Can I add a profile picture to my mailboxes?).

On Google Workspace mailboxes, a profile picture is set on the mailbox and can take time to appear for recipients — providers like Gmail cache sender avatars, so a newly set photo may not show immediately on the recipient side or inside your sequencer. Use a clear, square image.
