Emails: how to set frequencies

Global frequency cap

The global frequency cap is a tool for controlling how many emails a user can receive from all email campaigns within a defined time period. Use the expand button to open or close the settings panel.

Specify how many emails can be sent per user during a selected time interval (e.g., 1 email per day), then click Save to apply the changes.

Global frequency cap rules override the frequency caps set for individual email campaigns.

Frequency cap conflicts

When you save the global frequency cap, Meiro checks whether any campaigns have a less restrictive local cap.
If such campaigns exist, a confirmation modal appears before the change is applied.

What the confirmation modal shows

• A message explaining that the global cap will take priority because it is more restrictive.

• Information that campaign-level caps are preserved and will apply again if the global cap is raised later.

• A list of impacted campaigns (up to three displayed directly).

• A summary line if more campaigns are affected (e.g., “And 5 more…”).

• A warning icon (⚠️) marking each impacted campaign.

You can:

• Confirm to apply the stricter global cap, or

• Cancel to return without saving changes.

After confirming the global cap

If you confirm the stricter global cap, a Conflicting email campaigns section appears below the global frequency cap settings.

This section:

• Lists all campaigns whose individual caps are less strict than the global limit

• Marks each affected campaign with a warning icon (⚠️)

• Allows you to click into each campaign to review or adjust its settings

Campaigns continue to run normally but follow the stricter global frequency cap until either:

• Their individual campaign cap is adjusted to match or exceed the global cap, or

• The global cap is increased above their original local settings.

Local frequency cap

The local frequency caps are placed in every email campaign under the Activation tab. 

Specify the desired frequency of email delivery in terms of days or hours. The default limit is the same as the global limit. Save to apply changes.

If you use less strict limits in the local frequency cap than in the global, the campaign will be displayed in the list with a warning icon next to its name. The icon serves as a notification to the user, indicating that the campaign will continue to run based on the less strict limits specified in its local frequency cap.

To bypass the frequency limit for a specific campaign, select the "Ignore global frequency cap" checkbox. The campaign will be displayed in the list with a lightning icon next to its name.

Remember: If an Email has been set to ignore the global frequency cap, it will display regardless of the global limit and will not contribute to the global count of impressions.
