Warm-up score stuck or blocked

Your warmup score won't climb, or the mailbox shows Blocked/Paused. Read the phase, give it time, fix the mailbox connection and DNS, and let the ramp finish.

  1. 1

    Read the symptom: score still low after a couple of days

    You enabled warmup two days ago and the score is still low. Most of the time nothing is wrong — warmup builds reputation gradually over days, so a flat or slow-climbing score early on is expected, not broken. The real problems worth acting on are: an unverified mailbox, a disconnected mailbox, missing DNS authentication, or an explicit Blocked/Paused status.

  2. 2

    Read the phase label on the Warm Up tab

    Open Mailbox → Warmup and find the phase line:

    • Ramping up — Day N — normal, keep waiting.
    • Maintenance mode — done; the score plateaus by design.
    • Placement pending — scheduling active.
    • Paused — {reason} or Blocked — {reason} — something needs fixing.

    The label tells you whether to wait or act.

  3. 3

    If it says “Ramping up” — give it time

    A climbing ramp is working as intended. Don’t disable and re-enable warmup to try to speed it up — that pauses progress instead. A Healthy score (80+) takes days, not hours.

  4. 4

    If the mailbox is unverified

    The tab will say “Verify this connector before enabling warmup.” Warmup cannot run at all until the mailbox is verified — finish verification first, then the toggle becomes available.

  5. 5

    If it says Blocked or Paused — read the reason

    A red banner reads “Warmup blocked: {reason}” and names the cause. The two common fixes are reconnecting a disconnected mailbox and fixing DNS authentication.

  6. 6

    Reconnect the mailbox

    If the connection dropped, go to Mailbox → details and use Reconnect (OAuth). A dead connection stalls both sending and warmup, so this often clears a Blocked status by itself.

  7. 7

    Fix DNS authentication

    Confirm SPF, DKIM, and DMARC are all verified on the Email Authentication screen. Unauthenticated mail can’t reliably reach the inbox, which caps the warmup score no matter how long you wait. Once auth is green, let the ramp continue.

Pro tips

Hard-won shortcuts that keep warm-up on track.

1

Flat on day 1–2 is normal

Warmup is a multi-day ramp. The worst thing you can do is toggle it off and on, which resets progress instead of accelerating it.

2

80+ is Healthy, the plateau after is by design

Maintenance mode after reaching Healthy isn't a stall — it's the finished state. You don't need to push the score to 100.

3

Always read the status reason

Blocked and Paused both print exactly why right on the tab — reconnect or DNS authentication is usually the answer.

4

Fix the two gates, then be patient

Warmup can't start until the mailbox is Verified and can't climb past a ceiling until SPF/DKIM/DMARC are green. Handle those first.

Frequently asked questions

Why is my warmup score stuck?

Usually it isn’t stuck — it’s ramping and just needs more days. If it’s genuinely blocked, the tab shows a Blocked/Paused status with the reason, often a disconnected mailbox or unverified DNS.

How long until the score is Healthy?

A Healthy score (80+) builds over days of consistent warmup activity, not hours. The phase line shows “Ramping up — Day N” so you can track progress.

What does “Maintenance mode” mean — is it broken?

No, that’s the finished state. The score plateaus by design once warmup reaches maintenance.

My tab says “Verify this connector before enabling warmup.”

The mailbox isn’t verified yet. Verify it first — warmup cannot run on an unverified connector.

It says Blocked — what do I do?

Read the reason in the red banner. Reconnect the mailbox if the connection dropped, and confirm SPF/DKIM/DMARC are verified.

Should I turn warmup off and on to jump-start it?

No. Disabling warmup pauses your reputation progress (the app warns you of this). Leave it running.

Can I speed up the ramp or send more warmup email manually?

No — the ramp is automatic and there’s no manual volume or speed control on this tab. Fix any blockers and let it run.
