Building Email Drip Campaigns With AI in 5 Minutes
Use the /email-sequence skill to create, personalize, and send product launch email campaigns via the Resend API.
The Old Way vs. The OpenClaudia Way
Building a product launch email sequence traditionally means: sign up for Mailchimp or ConvertKit ($30–100/month), design templates, write copy for each email, set up automation rules, configure timing, and hit send. With OpenClaudia, it's one command.
Prerequisites
You'll need a Resend API key (free tier: 3,000 emails/month). Add it to your environment:
# ~/.claude/.env.global or .env
RESEND_API_KEY=re_your_key_here
Create Your Sequence
> /email-sequence --type product-launch
Claude will ask you a few questions:
- What's your product name and one-line description?
- Who's the target audience?
- What's the key benefit or differentiator?
- How many emails in the sequence? (default: 5)
Then it generates a complete drip sequence: welcome email, value proposition, social proof, urgency/scarcity, and final CTA. Each email includes subject line, preview text, and HTML body.
Review and Send
Before sending, Claude shows you each email for approval. You can edit any part — tweak a subject line, adjust the CTA, change the tone. Once you approve, emails are sent via the Resend API with proper headers, tracking, and unsubscribe links.
Pair With Subject Line Testing
Want to A/B test your subject lines? Chain it with the /email-subject-lines skill:
> /email-subject-lines "Product launch for developer tool"
✓ Generated 10 subject line variants with predicted open rates
Pick the best performers and plug them into your sequence. All from the terminal, all in under 5 minutes.
