Email notification character limit in Everbridge Suite.
Description:
Email notifications have a limit of 2500 characters. When text is entered into the message body portion of a notification, a counter displays the amount of remaining available characters.
If an email notification needs to exceed the 2500 character limit, or include custom content, such as HTML formatting, the Include a separate message for email notifications option can be used. There is no character limit when using the separate message option, but there is a 1 MB total size limit.
For more information on including separate messages for email notifications, please view the following articles:
When using the Everbridge API to send emails exceeding the 2500 character limit, you can use the custom email option in the API payload. Set useCustomEmail to true, and utilize the rtfContent field for HTML content, which does not have a character limit. Note that the title and textMessage fields should remain under 2500 characters combined.
When ingesting emails into Everbridge (for example, when an inbound email is used to populate the notification title and body), the 2500-character limit is applied to the combined content of the message title and body. In other words, Everbridge counts the characters in the subject line used as the message title plus the body/plain-text content together against the 2500-character maximum.
Because the ingestion process may also include additional hidden or expanded content—such as an expanded subject line, auto-generated metadata, banners, footers, or underlying HTML—the total number of characters passed into the title and plain-text body fields can exceed 2500 even if the visible email body appears short. In these cases, a “character limit exceeded” error can occur due to the combined subject + body size, including this extra content.
