The process of preparing an email address for general use or email outreach is commonly referred to as “Warming Up” an inbox, where you take a number of steps to ensure that an email address does not become deactivated, blacklisted, or automatically marked as spam when it begins to send outgoing messages to other recipients.

Warming Up an email inbox essentially is recreating the way a typical person will use an email address. Just by using your email address normally, you are ‘warming up’ your inbox by sending outgoing mail to other existing users. When you are reading your emails, starring/favoriting certain messages, and engaging in email threads with multiple other email addresses, you are building up your domain reputation in a way that shows that your account is being controlled by a real human being and is not being used to send out unsolicited emails that are trying to mislead/scam/defraud any other real people using their email inbox.

    The final note I'll make is that I've hand-rolled a few additional features that people are normally paying for.

I dont use customer.io for my email sequences — even though it's very good — because I was able to just build my own email sequencing system.
