Why are replies not appearing in MailRush?

Updated Nov 2, 2026

Replies appear only if they reach the inbox of the sending account and MailRush can sign in to it.

Checks

  • Outgoing campaigns only: replies arrive at your current provider. Turn on Reply forwarding in the account's DNS setup, or use Primary mail hosting.
  • Inbox filters: the Inbox tab shows campaign replies by default. Set Source to all replies, clear filters and check Others.
  • IMAP login: run Test authentication in Email Accounts. A failed IMAP login stops reply detection.
  • Reply forwarding: your provider must forward a copy that keeps the original message. Mail your provider files as spam is usually not forwarded.
  • Bounces and complaints are on the Feedback Loop page.
