How to Set Daily Limits and Send Time Windows

Why set limits and send times?

Daily limits cap how many emails a campaign sends per day so you don’t overload your inbox reputation or hit provider limits. Send time windows (e.g. 9:00–17:00) ensure emails go out only during business hours in the recipient’s timezone, which can improve opens and replies. You set both when creating or editing a campaign.

Where to set them

1. Go to Campaigns → New campaign or Edit an existing campaign.
2. Find the Schedule, Sending, or Limits section (often after you choose contact list and inboxes).

Daily limit

1. Daily limit — Enter the maximum number of emails this campaign can send per day (e.g. 50 or 100). The campaign will stop sending for the day once this number is reached and continue the next day.
2. This limit usually applies to the campaign as a whole (across all selected inboxes). Keep it within your plan and warmup recommendations.

Send time window

1. Start time and End time — Set the window when emails can be sent (e.g. 09:00 to 17:00). Only contacts whose local time falls in this window will receive emails at that time.
2. Timezone — Set the campaign timezone (e.g. America/New_York). EmaReach uses this (and the contact’s timezone if available) to send within the window.
3. Sends are typically spread across the window rather than all at once, depending on your plan.

Best practices

• Start with a conservative daily limit (e.g. 30–50) for new inboxes; increase as reputation builds.
• Use business-hour windows (e.g. 8–18) in the recipient’s region to improve engagement.
• If you have a "best send time" or analytics suggestion in the campaign form, consider using it.

Summary

Set daily limit and start/end time (and timezone) in the campaign form so sends are capped and only go out during your chosen window.
