No. Transactional email IP addresses do not go through HubSpot’s automated IP warm-up. Transactional emails are typically higher-quality, one-to-one emails that are triggered by a user’s behavior or interaction with a company. Because of this, and the high level of engagement that transactional messages receive, transactional IP addresses do not need to go through the same deliberate IP warming process as marketing IPs.
In some cases, you may need to manually warm up a new transactional IP if you plan to send a high volume of transactional messages right away that aren't triggered by a contact's actions, such as a privacy policy update. For advice on manual warm-up, please partner with your customer success manager.
