Sending & limits

Sending that checks every email before it goes out

Connect your Gmail or Google Workspace mailboxes and Engage decides, for each message, whether now is the right time to send it.

Mailboxes screen showing each mailbox with its sends in the last hour and last 24 hours against its limits

How does Engage decide when to send?

Before each email goes out, Engage checks the campaign window, the lead's local business hours and working days, the mailbox's rolling daily and hourly limits, frequency caps and cooldowns, a 24-hour company lockout and the suppression list. If any check fails, the email waits for the next allowed slot.

Connect with Google

Add a Gmail or Google Workspace mailbox with Google sign-in. Engage stores the access token encrypted and never asks for your password.

Daily and hourly limits

Each mailbox has its own rolling limits. Sends are paced evenly through the hour instead of in bursts, and a new mailbox can ramp up gradually to its target.

The lead's business hours

Emails go out inside each lead's local working hours and working days, so a lead in Sydney hears from you in the Sydney morning.

Company lockout and cooldowns

After one person at a company is emailed, the rest of that company waits 24 hours. Frequency caps and cross-campaign cooldowns stop the same lead being hit twice.

Suppression on every send

Unsubscribes, hard bounces and your do-not-contact list (single addresses or whole domains) are checked before every email, in every campaign.

Timing preview

Check timing shows when campaign hours and mailbox hours never overlap, before you launch, so no lead silently waits forever.

Frequently asked questions

How does Engage decide when to send?

Before each email goes out, Engage checks the campaign window, the lead's local business hours and working days, the mailbox's rolling daily and hourly limits, frequency caps and cooldowns, a 24-hour company lockout and the suppression list. If any check fails, the email waits for the next allowed slot.

Which email providers does Engage support?

Gmail and Google Workspace, connected with Google sign-in (OAuth). Other providers are not supported today.

Does Engage guarantee my emails reach the inbox?

No tool can guarantee inbox placement. Engage controls how and when you send: limits per mailbox, even pacing, local business hours, company lockouts and suppression. Your domain's SPF, DKIM and DMARC setup and the content you send still matter.

Does Engage include an email warm-up network?

No. A new mailbox can ramp up its daily volume gradually toward a target you set, but Engage does not exchange warm-up emails with other mailboxes.

Can I use my own tracking domain?

Yes. Each organisation can set a custom tracking domain for open and click tracking, and tracking links are signed so they cannot be tampered with.
