How are Sequence emails scheduled and prioritized?

This article explores factors that influence how Mixmax determines which emails should be sent first.

Updated over 9 months ago

Sequences are available on the Mixmax Small Business plan and above. Check out our pricing page for more information.

When activating a sequence, if you attempt to send more emails than your Daily limit allows, Mixmax will automatically reschedule emails across multiple days. Mixmax determines which emails should be sent first based on a number of factors, as outlined below:

1. Manually rescheduled emails are treated with the highest priority.

Emails you manually reschedule via the Outbox will be prioritized first.

2. The stage of the Sequence: Emails in later sequence stages get higher priority over emails in earlier stages.

Example: [email protected] is in Stage 2 of Sequence B, and [email protected] is in Stage 3 of Sequence B. If both emails are being considered for the same day, Jill's email will be prioritized ahead of Bob's because Jill is in Stage 3 while Bob is in Stage 2.

3. The number of days the recipient is in the Sequence: Recipients who have been active in a sequence longer are prioritized above recipients who have been active in a sequence for less time.

Example: [email protected] was added to a sequence 5 days ago, and [email protected] was added to a sequence 3 days ago. If both emails are being considered for the same day, Sarah's emails will be prioritized because she has been active in a sequence longer than Steven.

4. The scheduled send window: Emails with an earlier sending window get higher priority.

Example: Sequence A has an 8:00 am - 3:00 pm send window. Sequence B has a 10:00 am - 4:00 pm send window. If emails from both sequences are being considered for the same day, Sequence A will be prioritized because it has an earlier send window.

5. When the recipient was added: Recipient emails are prioritized based on which recipient is added to the sequence first.

Example: [email protected] was added to a sequence, and 1 hour later [email protected] was added to a sequence. If both emails are being considered for the same day, Bill's email will be prioritized because he was added to a sequence first.

6. Position of the recipient in the list: Recipients higher in the list have priority over recipients that are lower in the list.

Example: A CSV file of recipients is uploaded to a sequence. [email protected] is on row 5 of the CSV file. [email protected] is listed on row 30 of the CSV file. Lindsey's email will be prioritized since Lindsey has a higher position on the list.
