Context

When new mailboxes are added to your organization, you may be wondering when these email addresses will be ready to use as senders for your email sequences. New mailboxes need to go through a warming-up process before they can be fully utilized.

Answer

New mailboxes typically take 2 weeks to be fully warmed-up and ready to use as senders. This warming-up period is essential to establish a good sending reputation and ensure optimal deliverability for your email sequences.

During this time, the system gradually increases the sending volume from the new mailbox to build trust with email providers and avoid being flagged as spam.

If you're eager to launch sequences during this warm-up period, consider launching LinkedIn-only sequences.

If you have been waiting for approximately 2 weeks and your new mailbox is still not available as a sender option, please contact your Account Manager for assistance.
