We've heard from our customers that sequences reporting does not give a full picture of email performance, and customers must try to stitch this data together by viewing template and sequence reporting independently within HubSpot.
To solve this, we're building open and click reporting directly into Sequences.
If you're interested in getting early access to open and click reporting, upvote this post and we'll reach out to you to let you know as soon as it's available.
