When you approve an email, or turn on Autopilot for a campaign, your emails aren't sent all at once. They're added to your sending queue (visible on the right-hand side of your main dashboard) and go out one by one. This protects your sending reputation and keeps your account from being flagged as spam.
So if your emails look "stuck," they're usually just waiting their turn or waiting for the next sending window. Here's how the queue works, and what to check if emails really aren't moving.
Where to see your queue and today's activity
Click the activity icon at the top right of your Campaigns dashboard to open the activity panel. It shows two things:
Processed today: how many prospects, emails, and LinkedIn actions have already gone out today, broken down by user. It shows you your total daily capacity: the sum of the Smart Limits of every email account connected to your user. In the example below, 353 / 544 means 353 emails have been sent out of a combined daily limit of 544.
Scheduled: everything currently waiting in your queue to go out.
How the queue works
Emails in Overloop generally leave the queue in first-in, first-out (FIFO) order. Emails are sent in the order they were scheduled or became due.
There's one exception: follow-up emails take priority over first-touch emails. This keeps each prospect's sequence on cadence, so a follow-up that's due now won't get stuck behind a batch of brand-new first emails.
Example:
Prospect A: first email approved at 10:00 AM → enters the queue
Prospect B: first email approved at 10:05 AM → enters the queue
Prospect C: a follow-up becomes due at 10:06 AM → jumps ahead, because follow-ups are prioritized
Queue order: Prospect C → Prospect A → Prospect B
How quickly emails are sent
Overloop sends 1 email every 30 seconds. A maximum of 120 emails per hour per account.
If you schedule more than that (e.g., 300+ emails), it can take a few hours to clear the queue.
This pacing protects your email reputation and prevents sudden spikes that could get your account flagged as spam.
If your emails still aren't going out, check these three reasons:
Reason 1: Your campaign is outside its sending schedule
Campaign emails are only sent during the days and hours configured in your campaign's Settings > Scheduling section. Anything approved outside that window stays queued until the next available sending time.
Example:
Campaign schedule: Monday–Friday, 8:00 AM–5:00 PM (UTC+02)
You approve an email for a prospect at 4:30 PM your local time (UTC+01)
That's 5:30 PM in the campaign's time zone (past the 5:00 PM cutoff), so the email is queued for the next sending window
💡 Review your scheduling configuration, especially the time zone, to make sure emails go out during the days and hours you intend.
Reason 2: You've reached your daily Smart Limit
To protect your email reputation, Overloop caps how many emails each inbox can send per day: your Smart Limit. Once you hit that cap, no more emails are sent from that inbox for the rest of the day. Queued messages simply wait and resume automatically on the next sending day.
You can check this in the Processed today panel on the right side of your main dashboard: when the Emails count reaches its total (e.g., 350/350), you've used up your combined daily capacity for the day.
Reason 3: Your email account is disconnected
If your connected email account has lost its connection, Overloop can't send on your behalf and your emails will stay in the queue.
Go to Settings > Email accounts. If you see a red "In error" label next to an account, it needs to be reconnected (re-authenticated). You can do so by clicking on the concerned email address and re-authenticating. Once you reconnect it, your queued emails will resume sending automatically.
