AI writing
A first draft in seconds
Say what is new, or let it pick something from your website. It writes in your tone and links only to real pages on your site.
Email marketing that writes itself
Sunnyletter learns your business from your website, drafts your newsletters and welcome emails, and sends them when you approve.
Free for up to 1,000 subscribers. No credit card required.
Everything you need to keep customers coming back
Newsletters, welcome emails, signup forms and reports, with the writing done for you.
Autopilot
A newsletter every week, on its own
Choose weekly, fortnightly or monthly. A fresh draft arrives for you to approve, or sends itself after 48 hours.
Import
Bring your list from Mailchimp
Connect with an API key and bring over contacts, names and tags. People who unsubscribed stay unsubscribed.
Welcome emails
Greet every new subscriber
A three-email welcome series, written for you and spread over their first week. Included on every plan.
Signup forms
Grow your list from your website
Share a hosted signup page or paste a form into your site. Confirmation emails keep typos off your list.
Reports
See what people read
Opens, clicks on each link and unsubscribes for every campaign, without the clutter.
Up and running in three steps
Most people send their first newsletter on the day they sign up.
1
Add your website
Sunnyletter reads it and builds your brand profile: what you sell, who your customers are and how you sound.
2
Bring your contacts
Import from Mailchimp or a CSV file, or start fresh with a signup form on your website.
3
Approve and send
Review the draft, change anything you like, then send it now or schedule it for later.
Built to be trusted with your customers
Your newsletter carries your name, so Sunnyletter is careful with what it writes and who it writes to.
Only what's true
Drafts come from your own website and profile. No invented discounts, dates or reviews, and every link goes to a real page.
Your list stays private
The AI never sees your contacts. We never sell your list or email it for any other purpose.
Unsubscribes are respected
One-click unsubscribe in every email. Bounced addresses are removed, and a re-import can never resubscribe anyone.
Choose the plan that's right for you
Pay only for subscribed contacts. Every plan includes AI writing, autopilot, welcome emails, signup forms and Mailchimp import.

Frequently asked questions
Will the AI make things up about my business?
It writes only from your brand profile and the pages on your website, and it can only link to pages that exist there. It is told never to invent prices, discounts, dates or reviews. Nothing is sent until you approve it, unless you turn on automatic sending.
Can I bring my list over from Mailchimp?
Yes. Paste a Mailchimp API key, choose your audience, and your contacts come across with their names and tags. Anyone who unsubscribed or bounced in Mailchimp stays that way here, and importing them again can never resubscribe them.
Who counts toward my plan?
Only subscribed contacts. People who unsubscribed, bounced or never confirmed their signup are kept for your records, but they never count toward your plan.
Do I need my own domain or any technical setup?
No. You can start sending right away from our shared sending address. You'll add your postal address and a reply-to email, because anti-spam laws require both in marketing email.
Does the AI see my subscribers?
No. To write, it uses your brand profile and your public website. Your contact list stays in Sunnyletter and is never sent to the AI.
Can I cancel anytime?
Yes. Plans are monthly with no contract, and the Free plan stays free for up to 1,000 subscribers.
