The problem

Mailchimp and friends bill you by contact count and talk to you like a marketer. The price climbs every month, and you still stare at a blank campaign wondering what to write.

SendMerlin is one flat price with an AI that knows your shop. It suggests the next month of campaigns, drafts them in your tone, and tells you what happened in three human sentences.

What you get

A marketing brain, working for you.

What should I send?

Merlin reads your brand and the retail calendar, from Black Week to Dzień Matki, and proposes your next four weeks of campaigns. One click turns an idea into a draft.

Campaigns that write themselves

Subject lines, preheaders, and body content drop straight into the builder. Improve, shorten, or translate any block until it sounds like you.

Results in plain language

"214 opened, 19 clicked your offer, mostly on mobile in the evening. Next time: shorter subject." No dashboards to decode.

Merlin checks before you send

Broken links, image-only emails, missing alt text, spammy phrasing, subject length. Every campaign gets a once-over before it flies.

English and Polish, one click

Duplicate any campaign into the other language, with the subject and content localized rather than translated word for word.

Your own sending domain

Campaigns go out from news.yourshop.com, not a shared blast address. Merlin gives you the exact DNS records and verifies them for you.

How it works

From website to sent campaign in three steps.

01

Show Merlin your website

Paste your address. Merlin reads it and fills in your brand profile: what you sell, your tone, your languages.

02

Pick an idea, approve the draft

Choose from suggested campaigns. Merlin drafts the subject and content; you edit until it sounds like you. Nothing sends without your approval.

03

Send and actually understand

Your report is three human sentences and one clear tip for next time, not a wall of charts.

Why switch

Flat price. Your domain. Your data in the EU.

Most email tools charge by contact count, so the bill grows even when your sending doesn't. SendMerlin charges one flat price and includes the things the ladder locks away.

No contact-count ladder2,500 subscribers cost $29, flat. The same list on Mailchimp runs $45 to $75 a month, and keeps climbing as your list grows.

GDPR done properlyDouble opt-in by default, one-click unsubscribe in every email, and consent records you can show an auditor.

Your own sending domainSending from your domain builds your reputation instead of a shared pool's. Guided DNS setup is included on every plan.

EU and Polish firstYour data stays in the EU. Campaigns speak English and Polish, and the calendar knows Mikołajki from Black Week.

FAQ

Questions, answered.

Do I need marketing experience?

No. SendMerlin is built for owners, not marketers. It tells you what to send, writes the first draft, checks it before sending, and explains the results in plain sentences.

What does the AI actually do?

Four things: it proposes campaign ideas from your brand and the retail calendar, drafts subjects and content into the builder, reviews every campaign before it goes out, and turns reports into plain language. You approve everything; nothing sends itself.

Can I send in both English and Polish?

Yes. One click duplicates any campaign into the other language, with the subject and content localized. The campaign calendar also knows Polish retail moments like Mikołajki and Dzień Matki.

Is SendMerlin GDPR compliant?

Double opt-in is on by default, every email carries a one-click unsubscribe, consent records are stored for you, and your data is hosted in the EU.

Why do I send from my own domain?

Deliverability and trust. Emails from news.yourshop.com build your own sender reputation instead of sharing one with strangers. Merlin gives you the exact DNS records to add and verifies them for you.

What happens after the free trial?

The trial gives you full features for 14 days with up to 250 subscribers. After that you pick Starter at $29 or Growth at $59 per month. Both are flat prices; your bill doesn't grow with every new contact.
