Finding the Ideal Message Length

The length paradox

Longer messages signal effort, which is good. But they also raise the stakes of the reply - A short reply to a long message can feel awkward, which means people sometimes avoid replying at all rather than respond with what feels like an underwhelming answer. This is the length paradox: more effort can actually reduce replies. For the overall approach to openers, the guide there covers first impressions in more detail.

The solution is not to write less - It is to write the right amount. Enough to show genuine engagement, not so much that you are filling pages before they have agreed to talk to you.

Message length vs reply rate

What different lengths communicate

A very short message communicates either confidence (if the content is strong enough to stand on its own) or disengagement (if it is just a placeholder). Without exceptional content, short reads as low effort.

A medium-length message - Two to three sentences - Communicates that you had something specific to say and chose to say it without overwhelming them. It reads as measured and genuine, which is a good combination for a first impression.

A long message can communicate thoughtfulness or overthinking in equal measure. Without context, it is hard for the reader to know which. When in doubt, err shorter.

The sweet spot and why

• Two to three sentences is consistently the range that gets the highest response rates in most contexts. The first message generator defaults to this length for a reason.
• One genuine observation + one specific question fills that range naturally without padding.
• Short enough that a brief reply does not feel inadequate.
• Long enough to demonstrate you actually read their profile.
• Does not raise the stakes so high that replying feels like work.

How to edit a message that is too long

Read it back and ask: what is the one thing I actually want them to respond to? Cut everything that is not that, or is not setting it up. Most long first messages have two or three things they are trying to do at once - Pick the best one.

A useful test: could you send this to someone who did not have the background context you have about them? If the message only works because you have written it for this specific person, you are probably in good shape. If it reads like a general message with their name at the top, trim further. Once the exchange is going, the texting guide covers how to sustain it.
