Find Customers on Twitter: 3 Searches We Tested (2026)

To find customers on Twitter, search X for the questions buyers ask, like "what email marketing tool", and send new matches to your team chat.

This guide is for founders and marketers who sell a product people discuss on X (Twitter). We tested three common search types on 26 October 2026 and counted which one found real buyers. You get the winning search, a daily alert in Slack, Discord or Telegram, and its monthly cost. We run Weir, the API behind the alerts.

Paste this into X's search box, swap in your category and competitor, and pick Latest:

("what email marketing" OR "which email marketing" OR "recommend an email marketing" OR "switching from mailchimp") -filter:links lang:en

1. Write three searchesQuestions, rival names, and asks.
2. Test each by handCount the real buyers in 10 posts.
3. Tighten the winnerExclude the noise you saw.
4. Make it a monitorOne daily run, new posts only.
5. Send it to chatSlack, Discord or Telegram.

Step 1: Write three searches that find customers on Twitter

Buyers show up in three kinds of posts. Write one search for each, using your own category and the competitor people leave:

• Questions: "what email marketing" OR "which email marketing", the way a person asks friends.
• Rival names: "alternative to mailchimp" or "switching from mailchimp".
• Asks for help: "any recommendations" OR "looking for a" plus your category.

Quotes keep a phrase together, OR means any one of them, and a minus sign drops a word. X's own operator docs list the rest. Our X advanced search builder writes these from a form.

Step 2: Test each search and count the real asks

A search sounds good until you read its results. We ran all three through Weir on 26 October 2026, 10 posts each, in English, with reposts left out.

Then we read all 30 posts and sorted them by type:

Here is what each search really returned:

• "Alternative to mailchimp" was mostly makers. Half the posts launched or listed a rival product, and three discussed one viral launch.
• "Looking for a" drowned in hiring. Seven of ten were job ads or freelancers, even with -hiring -job in the query.
• The question search found two people asking which tool to use. The rest were promos and tips.

So the question search wins for leads. "Alternative to" is still useful, as a free feed of who is launching against your rival.

Step 3: Tighten the search before you automate it

Every word that keeps showing up in the noise belongs in an exclusion. From our 30 posts:

• Job posts used "intern", "apply" and "portfolio", so add -intern -apply -portfolio.
• A designer selling services wrote "Booking new clients", so add -booking.
• Media links slipped through. -filter:links didn't drop posts with a video, so read those twice.

Keep each change small, then search again by hand. A filter that is too tight hides the one buyer a week you wanted.

Step 4: Turn the search into a daily monitor

A Weir monitor runs your search on a schedule and keeps only posts it hasn't seen. It sends them to a webhook, and a Slack, Discord or Telegram webhook URL works directly.

Create the webhook first. For Slack, paste an incoming webhook URL:

curl -s https://api.weirapp.io/v1/webhooks \
  -H "Authorization: Bearer $WEIR_API_KEY" -H "Content-Type: application/json" \
  -d '{"name": "Buyers channel", "url": "https://hooks.slack.com/services/..."}'

Discord takes a channel webhook URL. Telegram takes your bot's sendMessage URL with the chat id on the end.

Then point a daily monitor at it, with your search as query:

curl -s https://api.weirapp.io/v1/monitors \
  -H "Authorization: Bearer $WEIR_API_KEY" -H "Content-Type: application/json" \
  -d '{"name": "Email tool buyers", "schedule": "daily", "webhookId": "<webhook id>",
       "target": {"kind": "search", "sources": ["x"],
         "query": "(\"what email marketing\" OR \"which email marketing\") -filter:links lang:en"}}'

Weir sends each delivery to the chat as a short message: the monitor's name, how many posts are new, and up to five with their links. POST /v1/webhooks/{id}/test sends a test message first, free.

Prefer to ask your agent? With Weir connected to Claude, ChatGPT or Cursor, paste:

Search X for "what email marketing" OR "which email marketing", English, latest 10.
For each post, tell me if it's someone choosing a tool. Show counts only, no names.

Step 5: Reply like a person, never by bot

Find buyers with code, then answer them by hand. X's developer guidelines allow automated replies "Only if user engaged first," and list "Auto-replies to random users, bulk DMs, uninvited @mentions" as prohibited.

A person asking "what tool do you use?" wants options, not a pitch. Name two or three tools, yours included, and say you work on it.

Our Twitter lead generation guide covers outreach rules and a second category in more depth.

What does a daily customer search cost?

Each monitor run costs 1 credit, plus 1 for each new post. A post it already sent you costs nothing again.

Our question search found 10 posts in about 10 weeks, so about 5 new posts a month:

Daily~35

Hourly~725

Daily fits easily in Weir's 5,000 free monthly credits. The free tier allows one monitor and one webhook, so put all your phrases in one query of up to 500 characters.

Hourly runs and more monitors need any $5 pack, which adds 25,000 credits that never expire. See pricing for the larger packs.

When not to use Weir

• One search a day by hand is enough. X's search box is free.
• You want a tool that replies or DMs. Weir is read-only, and X's rules ban that outreach.
• You need alerts within minutes. Monitors run hourly at best.
• Your buyers aren't on X. Search Reddit or your niche forums first.

Weir reads public posts only and isn't licensed by X, so access can change. Our acceptable use policy bans building profiles of individuals.

FAQ

How do I find customers on Twitter?

Search X for the questions buyers ask, like "what email marketing tool" or "which CRM", on the Latest tab. Read each match and reply by hand with honest options. A daily monitor can send new matches to Slack, Discord or Telegram.

What should I search on Twitter to find clients?

Phrases people use when choosing: "what [category] do you use", "which [category]", and "switching from [rival]". In our test, "looking for a" mostly found job ads, and "alternative to" mostly found competing launches.

Can I get alerts when someone asks for a recommendation on X?

X has no keyword alerts of its own. A scheduled search does the job: Weir's monitors run daily on the free tier and post new matches to a chat webhook. See Twitter keyword alerts for other routes.

Is it okay to DM people who tweet about a competitor?

Not with automation. X's developer guidelines allow automated DMs "Only after user DMs you first." A single, hand-written reply to a public question is the safer move.
