Sender display name
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 (Email accounts → Export accounts → Download selected accounts as 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. More on renaming: Change names of mailboxes (display name and address).
Profile picture: Google Workspace mailboxes only
Profile pictures (sender avatars) can be added on Google Workspace mailboxes only. They are not available on SMTP mailboxes.
Why not on SMTP mailboxes
An SMTP mailbox that carries a profile picture is easier to "footprint" — it gives spam filters another consistent signal to fingerprint and flag the mailbox, which can hurt deliverability. To protect your sending, we intentionally don't add avatars to SMTP mailboxes.
Setting a picture on Google Workspace mailboxes
Select the Google Workspace mailboxes on the Email accounts page and use Bulk actions → Change profile photo for Google. Use a clear, square image.
Use a static image (PNG/JPG) — animated GIFs are not supported as profile pictures.
It can take time to appear. Providers like Gmail cache sender avatars, so a newly set photo may not show right away for recipients or inside your sequencer.
If your photo still isn't showing after some time, contact us with the mailbox name and we'll check it.
