Once you have warmed up your IP address, you will need to send emails consistently in order to ensure your IP stays warm and keeping your reputation and sending cadence consistent with ISPs such as Gmail, Hotmail, Yahoo, etc. 

During IP warming: we recommend sending no more than 7 days between sends for a successful warm-up.

Once IP warmed: we recommend sending to your full engaged volume at least once every 2 weeks for consistent deliverability performance.
