Why did several of my mailboxes suddenly show "Reconnecting"?

If one or several of your mailboxes suddenly showed a connection problem — or a calm "Reconnecting…" status — here's the short version: this is almost always a brief, temporary hiccup on your email provider's side, not a problem with your password, your settings, or anything you did. It can happen even to mailboxes that have been warming healthily for weeks. WarmySender now recognizes this, keeps retrying automatically, and resumes warmup on its own once your provider is reachable again. It usually clears by itself, often within a day or so, and there's nothing you need to do. This page explains why it happens and what to expect.

WarmySender is a 4-pillar outreach platform — Cold Emailing, Email Warmup, LinkedIn Outreach, and Multichannel sequences. This guide covers an Email Warmup and mailbox-connection question: why a mailbox can briefly show "Reconnecting…" and why it recovers on its own.

What's actually happening

To warm up your mailbox and send your campaigns, WarmySender connects to your email provider many times throughout the day. Most of the time those connections go through instantly. Every now and then, though, a provider has a brief, temporary connection hiccup — a short window where connections time out or get dropped before they can complete.

When that short window happens, a mailbox can momentarily look like it has a connection problem, simply because WarmySender couldn't reach your provider for a moment. The mailbox itself is perfectly fine. So is your password, and so are your settings — especially if everything was working normally right before. It's the connection that had a brief wobble, not your account.

What the "Reconnecting…" status means

When WarmySender notices it couldn't reach your provider for a moment, it shows a calm "Reconnecting…" status on the affected mailbox instead of a scary red error — because in almost every case that's exactly what's going on: it's reconnecting. You'll also see a single, gentle notice at the top of the page so you're never left wondering. It's a status, not an alarm.

• We keep retrying for you. WarmySender automatically tries again on its own — there's nothing for you to restart.
• Warmup resumes by itself. As soon as your provider is reachable again, warmup picks up right where it left off. Your progress is kept.
• It's temporary. The "Reconnecting…" status clears on its own once the connection settles — usually on its own, often within a day or so.
• Even a mailbox that was already stuck recovers on its own. Whether a mailbox looked disconnected, showed a connection error, or simply looked connected while it had quietly stopped warming after a brief wobble, WarmySender now reaches back out to it and brings it back automatically — you don't need to remove it, re-add it, or re-enter anything to "unstick" it.

So if you see "Reconnecting…" — or a mailbox that briefly looked disconnected — you can safely leave everything as it is. It means WarmySender is already handling it.

Why several mailboxes can show it at the same time

You might notice several mailboxes go "Reconnecting…" together — and that's completely normal too. Mailboxes that are with the same email provider share the same connection to that provider. So if that provider has one of those brief hiccups, every mailbox relying on it can show "Reconnecting…" at the same moment, and then recover together once the connection settles.

Seeing a cluster of mailboxes reconnect at once can look dramatic, but it's usually a sign of a single short-lived hiccup on one provider — not a problem spread across your account. They'll come back the same way they went: together, and on their own.

What you need to do (almost always nothing)

In almost every case, the answer is: nothing. You don't need to remove and re-add the mailbox, change any credentials, or toggle warmup off and on. Doing so won't bring it back any faster, because the hiccup isn't caused by anything on your mailbox — it clears on its own once your provider settles.

If you'd like to nudge it along, there's an optional "Reconnect all" button on the warmup page. It simply re-checks the affected mailboxes right away instead of waiting for the next automatic retry. It's entirely optional — your mailboxes will recover without it — but it's there if you'd rather give it a gentle push and see them update sooner.

When it's genuinely a password problem instead

Sometimes — much more rarely — a mailbox really does need attention, because the password or sign-in for that mailbox has actually stopped working (for example, you changed your email password, or a security setting on the account changed). That's a different situation from the temporary "Reconnecting…" state.

When that's the case, WarmySender tells you clearly and asks you to reconnect that specific mailbox, with a direct prompt to update its credentials. So the rule of thumb is simple: if you only see a calm "Reconnecting…" status, it's the temporary kind and there's nothing to do. If instead WarmySender clearly asks you to reconnect a particular mailbox, follow that prompt for that one mailbox.

What it can do to your numbers (and what it doesn't)

While a mailbox is briefly reconnecting, it pauses sending and receiving warmup for that short window — so your warmup numbers for that mailbox can look a little flat, or move around more than usual day to day. That's a side effect of the temporary pause, not a real change in your deliverability.

Once the connection settles and warmup resumes, the numbers catch back up. The most reliable way to read your warmup health is the trend over a couple of weeks rather than any single day — especially a day when a mailbox was reconnecting. For more on how the warmup number is calculated, see Warmup shows active but no emails are arriving.

Frequently asked questions

Several of my mailboxes suddenly show "Reconnecting" — do I need to do anything?

Almost always, no. "Reconnecting…" means WarmySender briefly couldn't reach your email provider and is automatically trying again. It's usually a short-lived, temporary hiccup on the provider's side — not a problem with your password, your settings, or anything you did. WarmySender keeps retrying and resumes warmup on its own once your provider is reachable again, so you can safely leave everything as it is. It typically clears by itself, often within a day or so.

Did I do something wrong, or is my password broken?

Almost certainly not — especially if the mailboxes were working fine right before. The "Reconnecting…" status is about a brief connection hiccup on your provider's side, not about your password or your setup. A mailbox that's been warming healthily for weeks can show it just as easily as a new one. If it were genuinely a password problem, WarmySender would tell you clearly and ask you to reconnect that specific mailbox — which is a different message from the calm "Reconnecting…" status.

Why did several mailboxes go "Reconnecting" at the same moment?

Because mailboxes with the same email provider share the same connection to that provider. If that provider has a brief hiccup, every mailbox relying on it can show "Reconnecting…" at the same time — and then recover together once the connection settles. A cluster reconnecting at once usually points to a single short-lived hiccup on one provider, not a problem spread across your account.

Should I click "Reconnect all"?

You don't have to. Your mailboxes will recover on their own without it. The "Reconnect all" button on the warmup page is simply an optional way to re-check the affected mailboxes right away, instead of waiting for the next automatic retry. If you'd like to give things a gentle nudge and see them update sooner, you can use it — but it's there for convenience, not because anything is required.

Will my warmup or my progress be lost while a mailbox reconnects?

No. Warmup simply pauses for that mailbox during the brief window it can't reach your provider, and then resumes automatically right where it left off once the connection settles. Your warmup progress and history are kept — nothing is reset. Your other mailboxes that aren't affected keep running as normal.

How long does it take to recover?

In most cases it clears on its own, often within a day or so, as soon as the temporary hiccup on the provider's side passes. WarmySender keeps re-checking in the background, so you don't have to watch it or take any action. If you'd rather not wait, the optional "Reconnect all" button re-checks the affected mailboxes immediately.

One of my mailboxes was already stuck — showing an error, "disconnected", or just sitting connected without warming — will that one recover too?

Yes. Whether a mailbox got stuck looking disconnected, showing a connection error, or simply looking connected while it had quietly stopped warming after a brief wobble, WarmySender now reaches back out to it and brings it back on its own — so a box that was already stuck recovers the same way a freshly affected one does, and resumes warming automatically once your provider is healthy again. You don't need to remove it, re-add it, or re-enter anything to "unstick" it. The only time you'd take action is if WarmySender clearly and specifically asks you to reconnect that mailbox, which means it's genuinely a password or sign-in problem rather than a temporary hiccup.

A mailbox is still showing "Reconnecting" after a while — what should I do?

If a mailbox stays in "Reconnecting…" longer than you'd expect, first try the optional "Reconnect all" button on the warmup page to re-check it right away. If WarmySender determines it's actually a password or sign-in problem, it will switch to clearly asking you to reconnect that specific mailbox — follow that prompt and update its credentials. If it keeps showing "Reconnecting…" well beyond a day or so with no clear reconnect prompt, contact support and we'll take a look at that mailbox for you.

Will my cold email or LinkedIn campaigns be affected?

While a mailbox is briefly reconnecting, sending from that one mailbox pauses for that short window and then resumes automatically once the connection settles — so any sending from it simply waits rather than failing. Your other mailboxes carry on as normal, and your LinkedIn outreach is separate and unaffected. Once the mailbox reconnects, everything picks back up on its own.

Still seeing it after a while?

"Reconnecting…" almost always clears on its own, usually within a day or so. If a mailbox is still showing it well beyond that — and WarmySender hasn't switched to clearly asking you to reconnect that specific mailbox — we'd like to check it for you. Email [email protected] with the mailbox address and we'll take a look.
