Overview
Sequences are outreach campaigns that sales teams use to reach out to contacts over a planned period of time, with sequential touchpoints like phone calls, emails, social media engagement, and other tasks.
When you add contacts to a sequence, you choose which mailboxes the sequence should send emails from. By default, the selected mailbox is the one directly associated with your Apollo account, but you can choose other mailboxes, or rotate among your team mailboxes.
You can’t change the mailbox rotation setting for contacts that are already enrolled in a running sequence. Mailbox rotation is chosen only when you add contacts (from search, lists, CSV, or workflows).
After you add contacts to a sequence, users with edit access can still change the sending mailbox used to email contacts in the sequence.
Check out the following sections to edit the sending mailbox on contacts in a sequence.
Edit the Sending Mailbox on Contacts in a Sequence
To edit the sending mailbox on contacts in a sequence:
- Launch Apollo and click Sequences.
- Select your sequence.
- Click Contacts.
- Click Show filters, then click the Send Emails From filter. Enter an email address to find the right contacts.
- Check the contacts you want to edit, and click ... > Email from different user.
- Select a different mailbox to send emails from.
Apollo assigns tasks to the owner of the sending mailbox. If you change the sending mailbox, the task is automatically reassigned to the new mailbox owner.
- When finished, click Save.
You have now changed the linked mailbox for contacts in a sequence.
Your Apollo profile name is also the sender name for emails from your mailbox. Go to Settings > Profile to change the sender name displayed in sequence emails sent from your mailbox.
