Writing the first message

How to write a good first DM that actually gets read

The first DM is the whole ballgame. The recipient decides in a few seconds whether to reply, defer, or ignore — usually based on the first line alone. Writing a good first message is a learnable skill, and it comes down to a handful of principles. This guide breaks down how to write a first DM that gets read and answered.

The first line is everything

When someone gets a DM, they read the first line and make a snap judgment. If it is generic, self-serving, or unclear, they move on. If it is specific and relevant, they keep reading. Almost all of your effort should go into making that first line earn the second.

A strong first line shows you know who they are and gives them a reason to care. 'Hey, quick question' does neither. 'Loved your take on X in that thread about Y — it changed how I think about Z' does both.

The anatomy of a good first DM

A good first message has a clear, simple structure:

A specific opener that proves you know them and why you're writing.
One sentence of context — who you are or why this is relevant, only if needed.
One piece of value or one clear, small ask.
An easy out that makes not replying or saying no painless.

Keep it short and human

Length is a reply-killer. A first DM should be readable in a few seconds. If you find yourself writing a third paragraph, you are explaining too much — save it for after they reply. Brevity signals respect for their time and confidence in your message.

Tone matters as much as content. Write like a thoughtful human, not a press release or a sales script. Warmth and directness beat formality. Read it aloud; if it sounds stiff or salesy, rewrite it.

Make the ask effortless

The easier your ask is to fulfill, the more likely you get a reply. A first DM should ask for something answerable in a sentence — a quick opinion, a yes/no, a pointer. Save big asks like calls or detailed reviews for later in the relationship.

Counterintuitively, giving people an easy way to decline raises your reply rate. 'No worries if you're slammed' removes the pressure that makes people avoid replying at all.

Draft, check, then send deliberately

Before sending, run a three-point check: Is it specific to this person? Is there one clear, easy ask? Is it short and warm? If yes, send. If not, fix it first. The free DM template and opener tools on this site can help you structure a strong first message. And because writing good DMs takes a moment of focus, it helps to do it in a calm inbox — DMX keeps DMs open while the timeline stays bounded, so you can craft a thoughtful first message instead of dashing one off between scrolls.

Frequently asked questions

What should the first line of a DM be?

Something specific that proves you know who they are and gives them a reason to keep reading — ideally referencing something they made or said. Avoid generic openers like 'quick question.'

How long should a first DM be?

Short enough to read in a few seconds — typically a few lines. If you're into a third paragraph, you're over-explaining; save the rest for after they reply.

Why am I not getting replies to my first DMs?

Usually the message is too generic, too long, or asks for too much. Make it specific to the person, keep it short, ask for one easy thing, and give an easy out.
