How to promote an event on X (Twitter): Spaces, Communities, replies and DMs

Yes, but you have to build the event out of pieces. LinkedIn and Facebook give you an events page with an RSVP button. X gives you posts, Spaces, Communities and DMs. That's fine for founders, developers, AI builders and investors, because those are the people who live on X. It just means the registration link sits on your own page, and X is where you make people want to click it.

The highlighted row is the one most organizers skip. Posts and Spaces reach people who already follow you. DMs reach the 200 people you actually want in the room, whether they follow you or not.

The first post decides whether anyone reads the second. Lead with what attendees walk away with, who it's for, and when. Not your logo, not “we're excited to announce”.

1. 1Post 1: the outcome, the audience and the date. “40 SaaS founders, 1 day in Austin, Feb 12: how teams under 20 people are selling into enterprise.”
2. 2Post 2: the speakers, with handles, and one line on what each one will actually show.
3. 3Post 3: the format. Talks, workshops, dinner, how many seats. Small numbers sell.
4. 4Post 4: who should not come. It sounds odd, and it makes the right people lean in.
5. 5Post 5: the link, the price and the next deadline.

Pin it. Every reply and DM you send in the next 8 weeks sends people to your profile, and the pinned thread is what they see.

On hashtags: pick one short, unique tag for the event and use it for search and the day itself. It won't drive reach on its own. It does give speakers, sponsors and attendees one place to find each other, and gives you a list of people who are already talking about your event.

A Space is the closest thing X has to a live event preview. People hear the speakers, ask questions and get a feel for the room before they buy a seat. The catch is timing.

So a Space can't be your month-long countdown. Use it in the final stretch, which is when a lot of people decide anyway. In Livestorm's 2026 benchmark, 49.7% of webinar registrations came in the final 7 days. That's webinar data, not conferences, but the pattern holds for most events: the last 2 weeks are loud.

When you schedule a Space and share it in a post, people can tap to get a reminder, and they're notified when you go live, per X's help center. X's developer docs say a Space can have up to 10 speakers including the hosts, and that a Space can't be pulled through the API once it ends. Record it yourself and clip the best 60 seconds.

1. 1About 12 days out: schedule a 30-minute “meet the speakers” Space for day 10. Post it from your account and ask every speaker to quote it.
2. 2Day 10: run it. Each speaker shares one idea from their talk. Close with the seats left and the link.
3. 3Same day: post 2 or 3 clips, tagging the speaker.
4. 42 or 3 days before the event: a short “ask us anything” Space on logistics, the agenda and who's coming.
5. 5After each Space: reply to every listener who asked a question. They're your warmest leads.

Communities are topic groups on X: build in public, SaaS founders, AI builders, specific tools and niches. Everyone in them opted into the topic, which makes them the cleanest audience X has for an event about that topic.

Treat them like someone else's living room. Per X's help center, you need a public account to join, moderators can remove members, and each community's rules sit on top of X's own rules. A community full of founders will not welcome a registration link from someone who has never posted there.

• Join the 3 to 5 communities your attendees actually post in, weeks before you announce.
• Be useful there first: answer questions, share what you know.
• Ask a moderator before you post the event. Offer something the community gets: a discount code, a free seat, a recording.
• Post once per community, written for that community. No copy-paste blast across 10 of them.
• Read who engages. Members who ask about the topic are your invite list.

A DM from a stranger lands in Requests next to 40 pitches. A DM from the person who left a sharp reply under their post yesterday gets opened. That's the whole reason, and we go deeper in reply first, DM second.

The good reply has no event in it at all. It adds a real experience and asks a question. The event comes later, in private, a day or two after.

Yes, one at a time, to people who can receive your message. Per X's help center, someone who doesn't follow you can only get your DM if they've opted in to messages from anyone, if you're verified and they accept messages from verified accounts, or if they've messaged you before. Those messages sit in Requests until accepted, and X caps how many message requests each account can send a day, with higher caps on paid tiers.

The rules on volume are blunt. X's developer guidelines give a specific example of spam: an app that bulk-DMs users about a product launch. Swap “product launch” for “event” and you have most event promotion on X. Third-party trackers put the raw daily DM ceilings around 500 on free accounts and about 1,000 on Premium, but those are ceilings, not targets.

No link, one specific detail, one easy question. When she says yes, the AI or person on your side has to answer fast and answer the real question:

One follow-up a few days later if it goes quiet, with a new angle, like a new speaker. Then stop. More on writing these in X cold DMs that get replies and on the caps in X DM limits.

Your speakers' followers trust your speakers more than they will ever trust your brand account. That's not a hunch.

Most organizers ask speakers to “share the event” and get 1 retweet. Make it easy and specific instead:

• A quote card with their face and the title of their talk, sized for X.
• 3 draft posts in plain words they can edit: the announcement, one idea from the talk, the last week.
• Their own discount code, so they can see the seats they filled.
• A slot in the Space, so they have a reason to post about it.
• Exact dates: “could you post Tuesday, and quote the Space on the 2nd?”

Sponsors work the same way, with one addition: give them a number of invitations to send to their own customers, and track their code like everyone else's.

1. 1Week 4 out: pin the launch thread. Join communities. Build the list of 200 to 500 ideal attendees on X: speakers' followers, repliers on posts about your topic, community members.
2. 2Week 3: speaker cards and posts go live. Start replying to the posts of people on your list, a few a day.
3. 3Week 2: personal DMs to open inboxes, a day or two after each reply. Schedule the speakers' Space for day 10.
4. 4Week 1: run the Space, post clips, follow up once with anyone who went quiet. The logistics Space 2 or 3 days out.
5. 5Event day: use the hashtag, repost attendees, thank speakers. The day after, message everyone who registered and didn't show with the recording.
