If you want to simplify your email marketing, you might be wondering if you can use multiple email domains in Replyforce. Unfortunately, that's not currently possible – Replyforce only allows one active email account. That means you'll need to choose which email domain to use for your campaigns.
However, you can disconnect and reconnect an email account during a campaign if you need to switch to a different domain temporarily. While it's not ideal to be limited to one email domain at a time, this is a common limitation among email marketing tools.
