As the title says, I had a thought about Intro messages:

I think most of us can agree that users should be allowed only a single Intro message to each person they want to contact. This is to prevent repeated messages from anyone the recipient does not want to communicate with.

The one issue I think most apps have when it comes to Intros is what happens if the Intros remain unopened. On some apps like OkCupid, there are stories about Intros that were received late (sometimes for months) either due to technical complications or because a mutual match was required for the message to be received. Whatever the reason is, the message itself might not be relevant after so much time has passed.

I was thinking about placing a time limit on the unread Intros before they expire. For example, if an Intro sits in the recipient's Intro tab for a year and has never been read, it will disappear, and the sender will receive a notification so they can decide if they want to send another one.

This would help keep things organized by clearing out outdated Intros and eliminate the question of whether or not an Intro was ever received. To avoid putting too much pressure on the recipient to reply right away, I was thinking that an Intro that has been opened, could be automatically moved to their conversations / active messages (or whatever it's called) tab, and they can respond at a time of their choosing.
