Combine organic growth with paid promotion on X. Open this repo in Amp, Cursor, or VS Code and manage X (Twitter) ad campaigns with AI — promote tweets, target by trending topics, and amplify your brand's voice at pay-per-usage pricing (~$0.01/post).
X is where conversations shape markets. Product launches trend, CEOs build audiences, and brand crises unfold in real time. The platform's real-time nature creates advertising opportunities that don't exist anywhere else — you can promote content about a trending topic within minutes.
In 2025, X eliminated the $5,000/month Pro tier and moved to pay-per-usage pricing (~$0.01/post). This makes X Ads accessible to startups, solo founders, and SMBs for the first time. You can run meaningful campaigns for $100-500/month.
The best X Ads strategy isn't just paid — it's organic + paid together. Build your audience with valuable tweets, identify your best-performing content, then promote the winners. The AI agent can monitor trends, craft tweets, and manage the promotion pipeline.
Best for: Real-time marketing, B2B thought leadership, news/media, personal branding, SaaS founders, event promotion, trending topic newsjacking.

You: I'm a SaaS founder. I tweet regularly but want to amplify my best content. How?
Agent: The best X Ads strategy is the organic-to-paid flywheel:
Step 1: Identify winners. Let me analyze your last 30 days of tweets...
Your top 5 tweets by engagement:
- "We hit $1M ARR. Here's exactly what we spent on marketing to get there:" — 847 likes, 234 retweets
- Thread: "7 cold email templates that actually got replies from VPs" — 1,203 likes
- "Hot take: Your landing page doesn't need a video. It needs a better headline" — 432 likes
- "Just shipped: AI-powered analytics. Here's what it found in our data" — 318 likes
- "We're hiring a senior engineer. No leetcode. Here's our interview process:" — 567 likes
Step 2: Promote winners. Tweets #1 and #2 have proven organic resonance. Promoting them will reach 10-50x more people at $0.01-0.03 per engagement.
Step 3: Target the right audience.
- Followers of: @paborenstein, @dhaborenstein, @lennyrachitsky, @aaborenstein
- Interests: SaaS, Startups, Marketing
- Geo: US, UK, Canada
Budget: $25/day for 7 days = $175 total. Expected reach: 150,000-300,000 impressions.
You: Promote tweet #1 and #2. $25/day each.
Agent: Done. Both tweets now promoted with follower-look-alike targeting. I've set up Website Cards for both linking to your landing page. Remember: promoted ads on X can't contain URLs in the text body — use the Website Card instead.
You: A major competitor just had a data breach. Should we do anything on X?
Agent: This is a delicate opportunity. Here's my recommendation:
Do NOT:
- ❌ Directly attack the competitor (looks predatory)
- ❌ Mention the breach by name (legal risk)
- ❌ Use any hashtags related to the breach
Instead, do this:
- ✅ Post a helpful thread about security best practices: "We take data security seriously. Here are the 5 steps every SaaS company should take to protect customer data"
- ✅ Promote it to followers of the competitor's account
- ✅ Position your brand as the responsible alternative
The implied comparison is more powerful than a direct attack. People who follow your competitor are seeing breach coverage and your security-focused content in the same feed.
Timing: Post within the next 4-6 hours while it's trending, promote for 3 days.
Want me to draft the thread?
You: I want to grow my X following from 2,000 to 10,000. Can promoted posts help?
Agent: Yes, but followers campaigns work differently than engagement campaigns. Here's the strategy:
Campaign type: Followers objective Budget: $15/day ($450/month) Expected cost per follower: $1.50-3.00 Expected growth: 150-300 new followers/month from paid + organic boost
Targeting:
- Followers of accounts your ideal followers also follow
- Interests aligned with your content topics
- Exclude existing followers
The multiplier effect: Promoted tweets that gain followers also boost your organic reach. Every new follower sees your future organic tweets, creating a compounding effect.
Creative tip: Your promoted tweet should showcase your expertise, not ask for follows. "Here's how I grew our SaaS from $0 to $1M ARR in 18 months (thread)" outperforms "Follow me for SaaS growth tips."
You: Start with $15/day. Promote my best thread from last month.
Agent: Created. One important note: X Ads have strict content rules for promoted posts:
- Max 1 emoji total
- No ✅ (green checkmark emoji is banned)
- No URLs in tweet text (use Website Card)
- No hashtags in ad copy
I've verified your thread complies. Campaign is live.
You: We're hosting a virtual conference in 3 weeks. How do I promote it on X?
Agent: X is the best platform for event promotion — people check X to see what events industry leaders are attending. Here's a phased approach:
Phase 1: Awareness (3 weeks out) — $200 budget
- Promote the announcement tweet with event details + speaker lineup
- Target: Industry professionals, followers of speaker accounts
- Include a Website Card linking to registration
Phase 2: Speaker Spotlights (2 weeks out) — $150 budget
- Individual tweets highlighting each speaker with a pull quote
- Promote to each speaker's follower base
- Encourage speakers to retweet (free amplification)
Phase 3: Urgency (1 week out) — $100 budget
- "500 spots left — register now" with countdown
- Retarget people who clicked previous promoted tweets but didn't register
Phase 4: Live (Day of) — $50 budget
- Promote the live-tweet thread in real time
- Target people who engaged with any previous phase
Total budget: $500. Expected registrations from X: 200-400 (assuming $1.25-2.50 per registration).
You: Can I target followers of my competitors on X?
Agent: Yes — this is one of X's most powerful targeting features. You can target people who follow specific accounts (look-alikes of those followers, actually).
For your CRM product, I'd recommend targeting followers of:
Direct competitors:
- @HubSpot, @Salesforce, @Pipedrive, @monday, @notion
Industry influencers:
- @jaborenstein (SaaS founder), @aaronlevie (Box CEO)
- Relevant SaaS newsletter authors
Industry publications:
- @SaaStr, @ProductHunt, @TechCrunch
Pro tip: Create separate ad groups for competitor followers vs influencer followers. Competitor followers are further along the buyer journey — use direct product messaging. Influencer followers are earlier — use thought leadership content.
Audience Messaging @HubSpot followers "Outgrew HubSpot's free tier? Here's a CRM that scales with you" @SaaStr followers "We analyzed 500 SaaS companies' sales processes. Here's what the top 10% do differently" Want me to set this up?
- Organic first, paid second. Never promote content that flopped organically. If it didn't resonate with your existing audience, paid amplification just means more people ignore it.
- Pay-per-usage is a game changer. At ~$0.01 per post, you can test many content variations cheaply. Promote 10 tweets at $5 each, find the winner, then scale it.
- No URLs in promoted tweet text. X Ads policy prohibits URLs in ad copy. Use Website Cards instead — they render with a rich preview image and CTA button.
- Max 1 emoji, no ✅. X's quality policy limits promoted posts to 1 emoji maximum. The green checkmark (✅) is specifically banned. No hashtags either.
- Website Cards drive 2x more clicks. Always use the Website Card format instead of a plain tweet + link. The large preview image and CTA button dramatically improve click rates.
- Thread promotion works. Promote the first tweet in a thread — when users click, they see the entire thread. This works well for thought leadership and storytelling.
- Target competitor followers. X is the only major platform where you can target followers of specific accounts. Use this for competitive conquesting.
Yes — this repo. It pre-configures the Synter MCP server for X Ads management via OAuth 1.0a. Works with Amp, Cursor, VS Code, and Claude Desktop.
X moved to pay-per-usage pricing in 2025. Promoted posts cost ~$0.01 each. CPC typically ranges from $0.50-2.00 depending on targeting. You can run meaningful campaigns for $100-500/month.
Yes. The agent can draft tweets optimized for X's format (concise, opinionated, value-driven) and ensure they comply with X's promoted content policies (no URLs, max 1 emoji, no hashtags).
Yes. X Ads API requires OAuth 1.0a (not OAuth 2.0). The Synter MCP server handles this automatically — you don't need to manage OAuth keys.
Yes. Promote the first tweet in a thread, and when users click, they see the full thread. This is effective for long-form content like data analyses, how-to guides, and founder stories.
For B2B thought leadership, real-time marketing, and personal branding, X is unmatched. It's not the platform for ecommerce product ads (use Meta/TikTok), but for building authority and reaching professionals, X delivers.
