Customising your Sender Details

You can customise the sender field when creating your campaign in step 1. The email will be received by recipients as “Your agency name`` ``via Postman”, with the default sender email address for all Postman campaigns being donotreply@mail.postman.gov.sg.

You can also choose to send a copy of each email that each recipient in your contact list receives, by clicking on the "BCC to me" checkbox. This will send a copy of each email to your inbox.

We understand that logo refreshes happen from time to time. Logos can only be updated by the Postman team, so when you need your agency logo updated, send a request through our form here, and we will get back to you on the next steps!
