Hey Mia, your solution sounds feasible. However, there are at least a couple gotchas to be aware of.

- HubSpot offers no way to LOCK properties. So, once you perform your initial upload, there’s no way to protect those codes from being ‘modified’ once they’re in production -- i.e., after you send your emails.

- Everytime you need to add new codes you’ll need to perform additional uploads. This is true for one (1) code or 1000 codes -- unless, of course, you add them manually. 😐

Shouldn’t be a big deal if you don’t often have lots of new codes, AND you expect them to be used fairly quickly. Still not very scalable though.

Zapier should be able to ‘pick’ your codes from a Google Sheet based on HubSpot Contact email address. That may be a more manageable solution since, once setup, you’ll only need to add new contact email addresses (and their new coupon codes) to the Google Sheet.
