The short version
Mailchimp is one of the best-known email tools in the world, with more than 11 million customers, a free plan and over 300 integrations. mDOS does email and text marketing too, and adds a sales pipeline, cold email and LinkedIn outreach, your website, bookings and an online shop, at one price per site with every feature included. If you only need newsletters, Mailchimp is hard to beat on price. If email is one part of how you win customers, mDOS keeps it all in one place, with an AI team (Beta) and our marketing team on live chat.
How our software compares
This compares our software’s features only. Our AI agents and our partner Marketing Experts come on top, and no single tool here includes them. Every mDOS line is live today unless it says Beta. Every Mailchimp line comes from Mailchimp’s own website; “Not listed” means we couldn’t find it there. Checked on 9 Oct 2026; sources are listed below.
And on top of the software: AI agents that do the legwork, and vetted Marketing Experts running it with you. No single tool compared here includes them.
Where mDOS is stronger
- Fixed pricing: one price per site with every feature included, where Mailchimp prices by contacts and charges extra for text credits.
- A sales side Mailchimp doesn’t describe: a pipeline from enquiry to signed, plus cold email and LinkedIn outreach. Mailchimp says it isn’t a platform for cold emailing.
- Marketing tools included in every plan: SEO, AI search, social media, Google Business Profile, paid ads, artwork, digital PR (Beta) and visitor intelligence. Run them yourself, with the AI team (Beta), or let our marketing team run them on the Managed plan.
- A real marketing team on live chat on every plan, and on the Managed plan they run your marketing for you.
- Vetted Marketing Experts on the Managed plan: a Certified Partner Agency (such as Founding Partner Mr Digital) runs your marketing for you, under a retainer contracted and invoiced by that partner.
Where Mailchimp is stronger
- A free plan with no time limit, for up to 250 contacts.
- Scale and track record: more than 11 million customers, by its own count.
- A larger marketplace, with more than 300 integrations.
- A deep set of email-specific AI features, such as send-time optimisation and predictive segmentation, on mature sending infrastructure.

Moving from Mailchimp at your own pace
You don’t have to switch everything at once. Keep Mailchimp sending while we bring your contacts, tags and consent records across, then move your campaigns over when you’re ready. We agree a switching plan with you.
More than an email marketing tool
Unlike Mailchimp, mDOS isn’t only an email marketing tool. You get The Platform, The AI Agents and The Marketing Experts, working as one, at one price per site.
World-leading software
Not just an email marketing tool: your website, bookings, customer records, marketing and team tools in one system.
Tireless AI agents
AI agents draft campaigns, review replies and follow-ups for you to approve, and spot problems early. Nothing goes out without your approval.
Real experts driving it
