Say, we have a two-steps sequence: an initial email and a follow-up after 3 days. The “Threading” checkbox is on.
If the recipient doesn’t reply and doesn’t delete it, then everything works fine: he receives the follow-up email in the same thread, below the initial email. He sees the context - everything is right.
But if the recipient deletes the initial email, then a big problem occurs: when he receives the follow-up email, he doesn’t see the initial email in the thread. He’s out of context.
It happens because the subsequent emails (the follow-up email in this case) doesn’t include the previous discussion. When we usually press “Reply” in Gmail (or another email client), our message will include all the previous messages as a quote. In Sequences, it doesn’t. It’s bad.
Please, upgrade Sequences so the subsequent emails include previous replies. It should work like if press “Reply” button in an email client.
