Instantly campaign paused? How we restarted ours after two weeks offline

Sunny Ray · Oct 17, 2026 · 7 min read

When our own Instantly campaigns came back after a two-week outage, the restart wasn't clever. We duplicated the paused campaigns and restarted the copies, reduced the number of mailboxes per domain, and scaled back up slowly. Two or three leads came in the same day.

If your campaigns stopped sending and you're trying to get them going again, that's the short version: start fresh copies instead of fighting the old ones, send less per domain than before, and resist the urge to make up for lost time. Below is what happened, why each step matters, and what I'd tell any founder staring at a dashboard of paused campaigns.

The outage

For about two weeks, our campaigns were down. Not one campaign, the sending. That's a strange feeling when your business is booking conversations through cold email. The calendar keeps going for a while on momentum, and then it gets quiet.

I won't pretend we enjoyed it. When your whole engine runs on infrastructure you don't fully control, every outage is a reminder of that. But it was also a good test of whether we knew how to come back.

By our team call on October 9, the campaigns were back online. Here's how.

Duplicate and restart

The fix was to duplicate the paused campaigns and restart the copies. We did this for the campaigns that had been running for specific regions before the outage.

Why duplicate instead of just hitting resume? A campaign that's been paused for weeks carries its old state with it: where each contact was in the sequence, which steps were scheduled for when, which mailboxes were assigned. Resuming can dump a backlog of scheduled sends all at once, from mailboxes that haven't sent anything in two weeks. That's the opposite of what you want after a break.

A fresh copy lets you set the pace again. You choose the mailboxes, the daily limits and the start, instead of inheriting whatever the paused campaign had queued up.

One practical point: make sure the copy doesn't re-email people who already got every step or already replied. Check your lead list before you launch the duplicate.

Fewer boxes per domain

The second change was to reduce the number of mailboxes per domain. Each domain carries a reputation, and every mailbox on it adds to the load on that reputation. After an outage, you're not sure how the inbox providers see your domains anymore. So you make each one carry less.

That means more domains doing the same total volume, or less total volume for a while. Both are fine. What's not fine is putting the full pre-outage load back on the same domains on day one.

Scaling cautiously after a burn

The third rule was the hardest: scale cautiously to avoid burnout. Burnout here means mailboxes and domains that get flagged because they went from silent to loud too fast.

After two weeks of nothing, every instinct says to catch up. Send double. Get the pipeline back to where it was. That instinct is how you turn a two-week outage into a two-month one, because burned domains need replacing, and new domains need warming.

So we went slow. And the leads still came: two or three on the first day back.

Why we restart at all

Some founders take an outage as a sign to stop cold email. I understand the feeling. But on that same October 9 call we were looking at the other side of the numbers. The podcast pitch was converting about 50 to 60% of the time. That's the invite to come on the show. And what feeds the show is cold email.

The way I put it to the team: cold email is the engine that makes the podcast profitable. Without a steady flow of invites, the show runs on whoever you already know, and that runs out. With it, every week brings new guests who are the people you want to sell to or raise from.

So an outage isn't a reason to switch off the engine. It's a reason to make the engine harder to break.

A restart checklist

If your campaigns are paused right now, here's the order I'd go in:

1. Find out why they stopped. Billing, a provider shutting off an account, connection errors, or mailboxes flagged. The restart is different for each.
2. Check mailbox health before sending anything. Make sure each mailbox is connected and that warmup is running.
3. Duplicate the campaigns you want back. Clean the lead list in the copy so you don't re-send completed sequences or email people who already replied.
4. Spread across more domains, fewer mailboxes per domain.
5. Start below your old daily volume and raise it over days, not hours.
6. Watch replies and bounces daily for the first week. If bounces spike, stop and check the list or the sending setup before going further.

What to tell your clients or your team

If other people depend on your pipeline, the outage is also a communication problem. We kept our weekly calls going through it and were straight about what was down and when we expected it back. Nobody likes hearing "the sending is offline". They like it even less when they find out on their own.

Say what broke, what you're doing, and when you'll update them next. Then when the leads start coming back, say that too.

What not to do

A few things I'd avoid after any long pause. Don't resume everything at once. Don't switch to brand-new copy at the same moment you restart, because if replies are low you won't know whether it's the copy or the sending. Don't add a pile of new domains and send from them the same day; new domains need their own warmup. And don't skip the list check. Two weeks is long enough for some addresses to go stale.

Change one thing at a time. Restart the sending first, see it working, then go back to testing.

It's tempting to use a restart as a chance to fix everything you didn't like about the old campaigns. Resist it for a week. A clean restart gives you a baseline, and you need that baseline to know whether the next change helped.

What we changed after

The outage pushed us to look harder at where our sending depends on a single vendor, and to plan around it. That's a bigger topic, but the short version is we don't want any one provider to be able to switch off a client's pipeline overnight.

It's also part of why the gtm showrunner product handles the sending layer for you. Invites go from separate warmed sending domains, so your main domain stays clean. On the Growth plan, our warmed mailboxes are included, so you're not the one rebuilding domains when something breaks.

The real lesson

Outages happen. Every sending setup I've seen has had one. The founders who come out fine are the ones who come back slower than they want to. The ones who end up starting from scratch are the ones who tried to make up for lost time in a day.

If you'd rather not be the one restarting campaigns at midnight, look at the plans and let us run the sending.
