What changed

MailPoet's release announcement says version 5.43.0 pauses campaigns using an unauthenticated sender domain when a site has more than 200 subscribers. The administration notice identifies affected campaigns and the steps required to resume them. The update also improves email-list filtering and several background workflows.

Why merchants should care

A scheduled promotion depends on more than the email design. Someone must own the sending address, DNS configuration and campaign status. If those responsibilities are split between an agency and the store owner, a pause may be noticed only after the planned launch time.

A practical check

Review the From address on the actual campaign. Ask the person managing the domain to apply the records supplied in the account, then verify the service reports authentication as complete. Use a small internal send to inspect delivery and reply handling. Check paused campaigns individually before resuming them, particularly when the original promotion dates have passed.
