Optimized Sending — Deliver Every Email at the Perfect Time

Mailercloud now offers Optimized Sending, a send time optimization feature that automatically delivers your campaign to each contact at the hour they are most likely to open and engage — instead of sending everyone at the same fixed time.
Key highlights:

Each contact receives your email at their personal best hour, based on their historical open behaviour
You choose the start time — Mailercloud handles the rest across a 24-hour window
Contacts without engagement history are not skipped — they receive the email at the start of the window, just like a standard send
The "Audience engagement by hour" chart lets you preview how your contacts are distributed before you send
Works best for established audiences with sending history — ideal for re-engagement and regular campaigns
Available on paid plans

Stop guessing the best time to send. Let Mailercloud optimise it for every contact, automatically.
