Notification Content Length

For Developers

The limit of how much content can be sent in a notification is based on the body, title, customURL or any custom data you add. This is roughly 3500 characters for both Android (GCM) and iOS (APNS).

For Web Push, the limit is between 100 and 190 characters, depending on whether a long title is used.
