What's the best time to send a marketing email?

There is no universal best time, it depends on your audience and time zones. Mid-morning and early evening on weekdays are common starting points, but the reliable method is to test a couple of send times and compare open and click rates in your campaign reports.

Will scheduling cost extra?

No. Scheduling is included, and paid plans send unlimited emails. The Free plan includes 10,000 emails per month.

Can I send a test before the real send?

Yes, and you should. Send a test to yourself and check the subject line, links, images, and personalization tags on both desktop and mobile before the campaign goes out.

Can I cancel or edit a scheduled campaign?

Yes, as long as it hasn't started sending. Edit the content or change the scheduled time, then re-save. Once a send is in progress it can no longer be changed.

Paid plans include unlimited emails, and the Free plan covers 10,000 emails per month.

Send now or schedule

When your campaign is ready, choose to send immediately or pick a future send time. Scheduling is useful for hitting peak-engagement windows, lining up with a launch or promotion, or simply preparing work ahead of time. A scheduled campaign can be edited or cancelled right up until it begins sending, once delivery is in progress, it is locked.

Always send a test first

Before any real send, send a test to your own inbox and review it carefully:

Subject line and preview text, spelling, length, and that they read well together.
Links, click each one to confirm it goes where you expect.
Images, that they load and are not oversized.
Personalization, that merge tags like first name resolve, with a sensible fallback when a value is missing.
Mobile view, most opens happen on phones, so confirm it looks right there too.

Choosing a send time

There is no single best time for everyone. Audiences differ, and subscribers spread across time zones complicate any rule of thumb. Mid-morning and early evening on weekdays are reasonable starting points, but the right method is empirical: send the same or similar campaigns at two different times, then compare opens and clicks in your campaign reports. Over a few sends, a pattern for your audience emerges.

Protect deliverability when you scale up

As your list and send volume grow, pace matters. Sudden spikes in volume from a cold domain can hurt inbox placement. If you are new or sending large volumes for the first time, ramp gradually and keep an eye on engagement. For the fundamentals, see improve your sender reputation and make sure you have authenticated your domain so every scheduled send has the best chance of reaching the inbox.
