Email AI usage limits

There are certain limitations you should consider while using Email AI:

1) Character limit for custom prompts

To ensure that it accurately interprets your request, limit your custom prompts to 500 characters or less.

2) AI tokens per day

Email AI functionality comes with every premium plan and you’re not charged additional credits from your balance for using it.

However, to prevent functionality abuse and make sure every user gets a great AI experience, we put a limit of 15,000 AI tokens per day.

It’s all about how many requests (prompts) you can submit per day. The more complicated to process your prompt is, the more tokens it takes.

The limit is not displayed on the user interface, so you can’t check it, but don’t worry – it should be more than enough to meet your email writing needs. If you reach the daily limit, you’ll see an alert notification.

Errors and troubleshooting

You might occasionally experience some delays or see alerts when using Email AI. Here’s a quick recap of the possible errors:

Daily AI tokens limit reached: That’s because you’ve hit the daily token limit of 15,000. Just wait until tomorrow to continue using it. 

Email AI temporarily unavailable: That error message means Email AI is taking a break due to technical issues. Give it another shot later, please.

Email AI not responding: This error message suggests that Email AI is still busy processing your prompt. Just hang tight and wait for it to respond.

The email is too big: That error message means your email text is too long. Keep it under 2,000 characters so Email AI is able to process it.
