Outbound Copywriting
Test and rewrite CTAs for cold emails. Soft ask vs. hard ask vs. curiosity vs. value-first. The close of every email matters. Free Claude skill.
[cta-optimize]The Problem
"Would you be open to a 30-minute call next Tuesday at 2pm?" That CTA has killed more cold emails than bad subject lines ever will. It asks for too much, too specifically, too soon.
The CTA is the last thing your prospect reads. It determines whether they reply, ignore, or feel pressured. Most reps default to asking for a meeting because that's what they've been trained to do. But the goal of a cold email isn't a meeting — it's a reply. The meeting comes after the conversation starts.
The right CTA depends on the prospect's stage, the strength of your value prop, and the psychological approach that matches your audience. One-size-fits-all CTAs leave reply rates on the table.
What It Does
CTA Optimizer generates multiple CTA variants for any cold email, organized by psychological approach. It rewrites your existing CTA or generates new ones from scratch, giving you options to test across campaigns.
Every output includes:
Example
[cta-optimize] Optimize this CTA for a cold email to VP Marketing: "Would you be open to a 15-minute call to discuss how we can help with your outbound?"1. “Worth a look?” — Minimal commitment, easy yes/no
2. “Relevant to what you're building right now?” — Shows you understand their situation
3. “Happy to share how — just say the word.” — Puts them in control
4. “Curious — are you running outbound from HubSpot sequences or something else?” — Opens a conversation without asking for a meeting
5. “Any chance you've looked at this approach before?” — Implies there's something to learn
6. “I put together a 2-minute breakdown of how [similar company] runs this. Want me to send it over?” — Offers value, earns the reply
7. “Happy to share the framework we used with [customer] — no call needed.” — Removes the meeting barrier
8. “15 minutes to show you how this works — worth it?” — Clear ask but framed around value
9. “Can I send you 3 times that work this week?” — Assumes interest, drives scheduling
Recommendation: For cold outreach to VP Marketing, start with a soft ask (#2) or value-first (#6). VPs are meeting-fatigued. Earn the reply first, pitch the meeting in your response.

Add the skill instructions
Paste the skill prompt into your Project instructions. This teaches Claude the skill.
Start using it
Type `[cta-optimize]` followed by your current CTA or a description of the email and audience. The skill generates multiple CTA variants organized by approach.
Use Cases
Run "soft ask" vs. "value-first" CTAs in the same campaign to learn which approach your audience prefers.
Email 1 gets a soft ask. Email 2 gets a curiosity CTA. Email 3 gets a direct ask. The sequence builds naturally toward commitment.
If a campaign has decent open rates but low reply rates, the CTA is usually the problem. Swap it out without rewriting the whole email.
Enterprise deals need softer CTAs — you're starting a relationship. SMB deals can handle direct asks — the buying cycle is shorter.
Use the approach labels and analysis to teach your team why certain CTAs work better than others. The output is a CTA copywriting lesson in itself.
Skill Stack
Write the email first, then optimize the CTA separately for maximum impact.
Each email in a sequence should have a different CTA. Use this skill to vary the asks.
Design proper split tests around CTA variations to find what converts.
Optimize both ends of the email — subject line for opens, CTA for replies.
