Configure Email Campaign Rules

  • Updated

Before launching your campaign, review and configure the sending limits below. These rules help protect your sender reputation, keep you compliant with anti-spam regulations, and prevent contacts from being over-emailed.

All settings are configured under Settings → Email Sending Rules.

1. Per-User Hourly Cap

What it does: Limits how many emails each user can send per hour.

How to configure:

  1. Go to Settings → Email Sending Rules.
  2. Locate Per-User Hourly Cap.
  3. Enter the maximum number of emails allowed per hour.
  4. Click Save.

This prevents spam-like sending behavior and protects your domain's sender reputation.

2. Per-Contact Cooldown

What it does: Sets how many days must pass before the same contact can be emailed again.

How to configure:

  1. In Email Sending Rules, find Per-Contact Cooldown.
  2. Enter the number of days required between emails to the same contact.
  3. Click Save.

This ensures contacts aren't over-emailed and supports healthier long-term engagement.

3. Hourly Cap Per Contact 

What it does: Drip rules can now cap emails on an hourly basis per contact, not just per user — limiting how many emails a single contact can receive within a given hour, as an added layer of protection against over-communication.

How it works:

  • The system applies an hourly send cap per contact.
  • A cooldown period prevents repeat sends too close together.
  • Sending is controlled within a defined time window.

4. Allowed Sending Hours

What it does: Restricts outbound emails to specific hours, so messages don't go out at night or during off-hours.

How to configure:

  1. Go to Email Sending Rules.
  2. Set your Allowed Sending Hours (e.g., 8:00 AM – 6:00 PM).
  3. Click Save.

Important: Sending time windows are based on the sender's time zone, not the recipient's. This ensures proper time zone compliance, schedules messages within the sender's working hours, and keeps delivery timing consistent across campaigns.

Example: If a sender is in EST and sets allowed hours of 8 AM–6 PM, emails will send during that EST window — even if the recipient is in a different time zone.
