How do I warm up a new sending domain?
Start with your most engaged contacts in small batches, authenticate the domain fully, and raise volume gradually over days or weeks while watching bounces and complaints.
Mailbox providers distrust sudden volume from an unknown sender. Slow and steady builds reputation.
Do not warm with unengaged contacts, and avoid pausing and then resuming at full volume.
Keep notes on each stage of the ramp-up, and pause the increase if bounces or complaints rise, returning to the last volume that stayed healthy.
In practice.
A store starts with its most engaged few hundred contacts, doubles volume every few days while bounces and complaints stay low, and reaches the whole list after about three weeks.
