A: Thanks for the query. There is no direct limit on this. However, you should not use more than 5 parallel connections continuously for the power mode. We can understand that in some moments, you may need more than 5 parallel connections (i.e. 20 users submitted the registration form together), this is totally fine. But continuous usage of more than 5 parallel connections should be strictly avoided.

Please note that, we have a bulk email validation API endpoint available. If you need to verify a lot of emails using API together, you should use the Bulk Email API. You can submit up to 50,000 emails together via this endpoint. Our system will verify all the submitted emails as fast as possible.

Let us know if you have any other questions. Have a great day.
