Questions, answered
Do I really own the emails I design?
Yes. Every email you create is yours — export clean, production-ready HTML and send it from Letters, Klaviyo, Resend, Mailchimp, or anywhere else. We never lock your work in.
How is this cheaper than an agency?
Agencies bill retainers (often $3,000+/month) for a designer’s time. Letters uses AI to do the first 90% instantly, so you pay for software, not hours — from $19/month for unlimited emails.
What’s the difference between Pro and Studio?
Pro is unlimited design for one brand — you export and send wherever you like. Studio adds built-in sending (50k emails/month), a dedicated IP, custom domains, the transactional API, and room for multiple brands and teammates.
Can I change or cancel my plan anytime?
Anytime, from your account settings. Upgrades are prorated; downgrades and cancellations take effect at the end of your current billing period. No phone calls, no retention gauntlet.
Is there a free trial?
The Free plan is free forever (5 emails/month). Paid plans include a 14-day trial with no credit card required — design real emails and see the quality before you pay.
What if I send more than 50,000 emails a month?
Our Scale plan handles high volume with custom pricing, SSO, audit logs, an SLA, and a dedicated contact. Get in touch and we’ll size it with you.
