November 24, 2025 - Intelligent Warm-up

We're introducing a new Intelligent Warm-up mode within Recurring Automations to help you manage your email sender reputation by gradually increasing sending volumes.

• Users can define and manage the warm-up process with three key parameters:

  • Initial Sending Volume: The volume for the first day's send (default: 500).

  • Volume Increase Percentage: The percentage increase applied to the sending volume for each subsequent day (default: 50%).

  • Engagement Selection Criteria: A profile attribute used to target people from the most engaged to the least engaged.

• Several parameters can be modified during the warm-up process to maintain flexibility and adapt to issues that may arise (poor targeting, volumes increasing too quickly, being blocked by a provider, etc.). Learn more on our documentation.
