You don't need decades to become an email marketing expert.
1 Research
See what real brands send before you write a word.
We're a B2B SaaS. What does a product-launch announcement email from good SaaS brands look like structurally: hero, sections, CTA placement, length? Real examples please.
2 Benchmark
Know what's common, not what a blog post claims.
Our startup sends exactly three emails: a welcome, a payment receipt, and a monthly newsletter. Based on what real companies send, what lifecycle moments are we missing, and which one should we add first?
3 Plan
Build your email plan from real examples, not a template.
Based on real BFCM emails from real brands, what should our send calendar look like: how many emails, what sequence of angles?
4 Write
Paste your current email. Get fixes backed by real examples.
Here's the welcome email we send. Compare it against [Competitor A] and [Competitor B]'s welcome emails. What are they doing that we're not, and what's the one change I should make first?

Common questions
Is Curcuma free?
Yes, Curcuma is free enough for everyday email research and writing.
Which agents work?

What kind of emails does Curcuma have?
Real marketing emails from over 4,300 brands: welcome emails, cart reminders, newsletters, banking offers, SaaS onboarding, and many more.
Does Curcuma have full email sequences?
Yes. Your agent pulls real emails for each stage, welcome, cart abandonment, winback, and builds the plan from those.
What does my AI agent get from Curcuma that it doesn't already have?
