A: Hello, thanks for reaching out!

There's no limit. SendFox doesn't use a list of sender accounts: every email and every automation email has its own From email field, so you can type a different address for each one.

To send from your own address, verify its domain under Settings > Sending > Email domains by adding three CNAME records to your DNS. Once a domain is verified, any address on it sends as itself, and you can add as many domains as you like. If an address's domain isn't verified, the email goes out from [email protected] and your address becomes the reply-to, so replies still come to you.
