Email and LinkedIn steps
Plan a first email, LinkedIn steps and follow-ups with waits between each one, written once and personalised for every contact.
Sends from your mailbox
Messages go from your own connected mailbox, so replies come straight back to you.
Safe sending pace
Daily limits and natural timing protect your mailbox from being flagged as spam.
Stops when they reply
Replies and bounces are spotted, and the sequence stops for that person straight away.
Clicks and replies tracked
See opens, clicks and replies for every step, with opt-outs honoured.
Linked to your pipeline
Contacts, companies and deals stay in your CRM, and you can see which campaigns led to revenue.
Every feature, in detail
Everything below comes with every plan, at one price per site, with no add-ons or per-user fees.
Make it yours. Let it do the legwork.
Work three ways: do it yourself, ask your AI teammate, or let them draft it and take over. A draft lands as a normal item you can edit, not a block of text to copy and paste.

Your inbox, your pace
Send from your own inbox or a verified alias, with your own daily cap, warm-up and sending times.

Stops when they reply
A sequence stops the moment someone replies, bounces are caught, and opt-outs are always honoured.
Arun drafts it, you take over
Do it yourself: build sequences in the campaign builder.
Ask Arun: Arun builds and runs your outreach from your own inbox.
Or take over the draft: it lands as a campaign in the normal builder, with each send held for review if you choose.

YOUR AI TEAM, ON OUTREACH
It writes, checks and watches your sequences
It works around the clock once you switch it on. Nothing goes out without your approval.
Messages written for you
Drafts and refines each step’s copy for the person and company you’re writing to.
Checked before they send
Reviews each message waiting for approval for personalisation, tone and compliance.
Sequence health
Flags rising bounces, falling replies or stalled steps so you can fix them early.
Set up by real people, supported by AI. An mDOS Expert Partner connects your mailboxes and sets safe sending limits with you and is a call away, while the AI team drafts and checks messages and you approve them.
Switch at your own pace
Start one new sequence in mDOS while your current outreach tool runs out its contract. We bring your contacts and companies across and agree a tailored switching plan, so no campaign stops mid-flow.
Three things no one else brings together
Sequences are only as good as the messages in them. mDOS gives you the sending tool, AI agents that write and check every step, and experts to set it up safely.

World-leading software
Email and LinkedIn sequences that send at a safe pace from your own accounts and stop the moment someone replies.

Tireless AI agents
AI agents draft each step for the person you’re writing to, check every message for tone and compliance before you approve it, and flag rising bounces early.

Real experts driving it
An mDOS Expert Partner connects your mailboxes and sets safe sending limits with you, and partner marketers can help you plan the message behind each sequence.
Keep the tools that work for you. Replace the ones that don't.
Keep your CRM and website. mDOS adds the outreach, ads and reporting, and keeps your records in step.
