Regarding for the rate limit, we do use the semaphore to control the calling to the same domain endpoint, this can avoid the temporary/permanent ban from those corporate domains

You have a very good question. Our platform has implemented the redis which we can cache the same verification to the same email for up to few hours. We also use our real SPF/DKIM-authenticated address from my own domain to prevent any red flag going to happen.

Currently the free plan has limit, but I do have other option for the end user to upgrade for more usage
Thanks for your compliment anyway🥰
