A dedicated Email Warm Up tab
Warm up traffic used to blend into your regular inbox view, which made it harder to tell what was a real reply and what was your own warm up system talking to itself. There is now a dedicated Email Warm Up tab, with its own counts, and warm up messages with unusual subject formats are classified correctly instead of leaking into the wrong place.
What changed
Email warm up, the sends and replies your account exchanges with other inboxes to build sender reputation, now lives in its own tab, separate from the inbox where your real prospect conversations happen. Previously, these two kinds of traffic could end up mixed together, which meant your reply counts and unread counts could include messages that were never from an actual prospect, making your inbox harder to trust at a glance.
The Email Warm Up tab has its own counts, tracked independently from your main inbox. That means when you check your inbox for real prospect replies, you are looking at a view that reflects only that, not warm up chatter sitting alongside it and inflating the numbers you rely on to know what needs your attention.
This release also fixes how warm up messages with unusual subject line formats are handled. Some warm up traffic uses subject formats that do not match the typical pattern the system expects, and previously that could cause misclassification, where a warm up message might not get recognized correctly or could end up somewhere it should not, including your main inbox. That classification is now accurate for these edge cases as well, so the separation holds even for warm up traffic that does not follow the usual pattern.
Warm up traffic naturally varies more than you might expect. Different sending providers and different inboxes on the other end of a warm up exchange format their subject lines differently, and any system built to separate warm up from real conversation has to handle that variety correctly, not just the common case. The fix here specifically targets those less common formats, since those were exactly the messages most likely to slip past the previous classification and land somewhere they should not have.
How to use it
Open your inbox and look for the new Email Warm Up tab alongside your existing views. Click into it to see warm up sends and replies on their own, with counts that reflect only that traffic, so you can spot check that warm up is running as expected without it competing for your attention.
Use your main inbox as you always have, for real prospect conversations. You should no longer need to mentally filter out warm up noise while scanning for actual replies, since it now lives somewhere else entirely, and the counts you see there are counts you can act on directly.
If you were previously using workarounds, like ignoring certain senders or manually marking warm up threads as read to keep your inbox clean, you can stop. The separation now happens automatically, and unusual warm up subject formats that used to slip through are now caught correctly too, so those workarounds should no longer be necessary.
It is worth glancing at the Email Warm Up tab occasionally even though it is not where your prospect conversations live. A healthy warm up pattern, steady sends and replies without sudden gaps, is part of what protects your ability to land in the primary inbox on real outreach. If warm up activity looks unusually sparse or erratic, that is worth noticing before it affects deliverability on the campaigns that actually matter to your pipeline.
Why it matters
Warm up exists to protect your sender reputation, not to compete for your attention. When it shared a view with your real inbox, it added noise to the one place you need to be able to trust: your list of actual prospect replies. An inflated or inaccurate unread count, or a real reply buried among warm up traffic, costs you time and can cost you a response if you miss it entirely in the clutter.
Separating the two, and fixing the classification gap for unusual subject formats, means your inbox counts now mean what they say. When the Email Warm Up tab shows a number, it is warm up. When your main inbox shows a number, it is real conversations with prospects, not something you have to double check before you trust it.
This distinction becomes more important the more inboxes and the more warm up volume you run. A single account with light warm up traffic might barely notice the old mixing; an account running warm up across several sending inboxes at once would have felt it constantly, with warm up noise scaling right alongside the real activity it was meant to protect. Separating the two scales the same way in reverse: the more warm up you run, the more this change actually saves you.
For accounts onboarding a brand new sending inbox, warm up activity is often at its heaviest in the first couple of weeks, which is exactly the period where mixing it with real replies would have been most disruptive. Having the two separated from day one means a new inbox's ramp-up period is no longer the noisiest, most confusing time to be checking your inbox.
It is a small change on paper, one tab instead of one blended view, but it removes a category of doubt every time you open your inbox: whether the number you are looking at reflects real interest from a prospect or just the ordinary hum of warm up doing its job in the background.
Availability
The Email Warm Up tab and improved subject format classification are live now for all accounts running email warm up, with no setup required on your side. Existing warm up history reflects the correct classification going forward, and the separation applies to every sending inbox in your workspace, not just newly connected ones, whether that inbox has been warming up for a day or for months.
