Hey ​@Twine,

That’s a good question! In general, there’s no “wrong” number of flows to have, but with that comes some things to consider. 

If you’re early in the process of setting up your account, I’d recommend focusing mainly on essential, high-performing flows, like a Welcome flow, Abandoned Checkout flow, Abandoned Cart flow, and a Customer Thank You flow. Flows like the Welcome and Thank You flows are really important because they allow your new customers/subscribers to learn more about your company and feel valued, while abandonment flows can be really effective at recovering carts and generating revenue. 

Before moving onto other flows (like Browse Abandonment, Birthday, Sunset, ect), check to make sure that these flows have interesting messages, and are generally working (people are entering, the filters are correct, and the splits and time delays allow people to move through the flow in an expected way). Once these are set up, sending and generating revenue, it’s not a bad idea to add some more flows! I wouldn’t say there’s a hard limit to the amount you should have, but each flow should have a distinct purpose, and I wouldn’t recommend having more flows than you can reasonably analyze/edit/check up on.

Having a large amount of flows doesn’t directly correlate to deliverability issues. Inboxes don’t know how many flows you have. They just know you’re sending people emails. As long as people are opening the emails in your flows, those emails aren’t bouncing, and people are not unsubscribing/marking them as spam, then the number of flows you have shouldn’t be an issue.
