Sending to an imported list depends on contact eligibility, your sending-account status and campaign delivery checks. A cold-contact label alone does not remove someone from your contact list.

This helps protect your sending reputation before you email anyone on that list.

Some large or cold-list campaigns start with a smaller trial batch, and the remaining messages wait for delivery results. Separately, an account paused for bounce or complaint problems can be blocked before any campaign messages go out.

This is not a punishment. It is a safeguard so your emails keep reaching the people who actually want them.

A campaign hold does not delete your contacts.

A hold can apply to one campaign. Contact opt-outs and email-provider suppression can also affect who is eligible to receive messages.

Trial batches and hourly sending limits can prevent a large campaign from going out all at once.

Sending to a large batch of cold contacts at once risks getting your sending account suspended by our email infrastructure provider, which would affect your ability to send any emails at all.

If the trial batch clears its delivery checks, the campaign can continue, subject to the other sending limits and eligibility checks. A failed or unresolved trial can leave the campaign halted.

Check your campaign status and Delivery health in Email Marketing. If sending is blocked or a campaign remains halted, contact support; do not assume that contacts will be automatically reintroduced over time.
