@CEberhardt For sales emails, the guidance is the same, but the requirements for all senders do not involve changes managed in HubSpot the way that marketing email does. You should work with your IT team to ensure you have SPF or DKIM authentication set up in your DNS records, and a DMARC policy configured. You should also be reviewing your spam rates in Google Postmaster Tools.
If you are a bulk sender, there are a few more requirements. Note: If you’re using the same domain for marketing and sales, it all counts towards that 5,000 email/day consideration, so it’s certainly possible to be a bulk sender of sales email if the overall volume of the sending domain is that high. The unsubscribe requirement for bulk senders is the reason we are recommending opting into unsubscribe links for sales emails. It is unclear how strictly Google will hold non-marketing emails to this standard, but reading the most recent FAQs mentioning “commercial” emails means it is likely. One important note is that Google is starting with personal gmail.com recipients, not Google Workspace accounts, so B2C senders might feel the impact of the changes sooner.
Ultimately, Google and Yahoo aren’t going to tell us everything, and they are going to continue tightening the requirements as time goes on. Our overall recommendation is to start following all the guidelines you can as quickly as you can. Check Google Postmaster Tools to understand what kind of volume and spam rates you have today. If you’re sending close to or over 5k/day, and to a lot of gmail.com recipients, you should strongly consider opting into unsubscribe links for sales email sends.
