Mailer Mark: newsletters and cold emails that bring in customers
Mailer Mark is your email expert, coming soon. Here's how he'll work: newsletters that keep customers coming back, and personal cold emails that win new ones — in your voice, landing in the inbox.
My AI CrewJoe, Susy & Mark
Email is still one of the best ways to win and keep customers, but it takes time: a blank template every month, prospects you never get round to writing to, and emails that end up in spam. Mailer Mark is your email expert: you chat, he writes and sends. He's coming soon — this is how he'll work.
1. Newsletters that keep customers coming back
Tell Mark what's going on — a new product, a seasonal offer, an event or just news from the business — in your own words, typed or spoken. He turns it into a newsletter for the people who already know you, and keeps it going every month, even in busy weeks. Already have a list? Bring it along. Starting from zero? He helps you gather customers and followers who want your news.
2. Cold emails that win new customers
Tell Mark who your ideal customer is — say, local gyms, dental clinics or property managers. He writes short, personal emails that explain why you're worth a reply, and follows up politely if there's no answer. No mass blasts: each email is relevant to the business it goes to, every email has an easy opt-out, and he follows the rules (GDPR and CAN-SPAM).
3. In your voice
Mark learns how you talk — friendly, formal, playful — and writes subject lines and emails that sound like you, not like a template. Each one shows up in the chat for your OK. Change anything by just asking: “shorter”, “mention the Saturday opening”, “less salesy”.
4. In the inbox, not in spam
Good emails are useless if nobody sees them. Mark helps you set up your sending domain properly (the SPF, DKIM and DMARC records that prove the email really comes from you), sends at a sensible pace and keeps your lists clean — explained in plain words, step by step.
5. Simple stats
After each send, Mark tells you in plain words how it went: opens, clicks and replies, and what he'd try next time. Replies to cold emails come straight to you. No dashboards to learn.
Questions and answers
- When is Mailer Mark available?
- Mailer Mark is coming soon. Sign up for early access at mailer-mark.com and you'll be among the first to try him.
- What's the difference between a newsletter and a cold email?
- A newsletter goes to people who already know you and signed up — customers and fans. A cold email is a short, personal message to a business that doesn't know you yet but could really use what you offer. Mark does both, and keeps them separate.
- Is cold email allowed?
- Yes, when it's done properly: relevant business contacts, an honest sender, and an easy way to opt out. Mark follows the rules (GDPR and CAN-SPAM), includes an opt-out in every email and never writes to anyone who said no.
- Will Mark send emails without asking me?
- No. Like the rest of the crew, Mark shows you each email in the chat and waits for your OK before anything goes out.
