Warming

Troubleshooting failed warmup

Warming fails when authentication is wrong, the mailbox cannot send or receive, placement stays in spam, or a bounce trips an automatic hold. This page is the EmailPal checklist for fixing the cause.

What "failed warmup" means

A mailbox cannot complete its scheduled warming actions. On EmailPal that usually looks like a hold, a bounce, paused warming, or an inbox rate that never improves, even after the 14-day campaign-ready flag.

Warming is $0.60/mo and talks to a network of real Gmail, Outlook and Yahoo inboxes. If those conversations cannot leave or come back, the ramp stalls.

Checklist

  1. DNS is actually public. Open the domain in the dashboard. SPF, both DKIM selectors, DMARC and MX must be green against public resolvers, not just our nameserver. See DNS verification failed and DKIM not validating.
  2. The mailbox can send. SMTP credentials work and the mailbox still exists. Warming only runs on mailboxes EmailPal hosts. See Can I warm Gmail, Outlook or my own server?.
  3. The mailbox can receive. Warming is a conversation. If IMAP is down or MX is wrong, replies never land and the mailbox looks dead.
  4. Warming is not paused. Resume it from the mailbox row. See Enable, pause or resume warming.
  5. You are not blasting on top of the ramp. Campaign volume during warmup is the most common self-inflicted failure.
  6. The list is clean if you already started sending. A burst of bounces will hold warming. Verify first: How to verify an email list before sending.

Bounce holds

A warming bounce can disable the ramp so we do not keep hitting a mailbox that is rejecting. See Warmup bounce and disabled warmup.

When to replace the mailbox

If DNS is perfect, the mailbox sends and receives, and placement is still junk after a full standard ramp, the domain may already be burned. Do not keep pushing volume. Register a new domain or claim pre-warmed inventory instead of "trying harder" on a bad name.

FAQs

Does restarting warming reset reputation?

No. Providers still remember the domain. Restarting only resumes the conversations.

Why do I receive more warmup mail than I send?

The network replies to you. Receiving more than you send is normal. See the related question in Email warming by EmailPal.
