Cold Emails That Feel Warm and Personal

AI researches each prospect and crafts individually tailored messages. You review every email before it sends to protect your reputation.


Why this matters

Generic cold emails get less than 1% response rates and damage sender reputation. Personalized outreach works dramatically better but takes 15-20 minutes per email to research the prospect, find a relevant hook, and compose a natural-sounding message. This makes quality outreach at scale impossible for most teams.


How MultiMail solves this

MultiMail's AI agent researches each prospect, finds personalization angles, and drafts individually crafted cold emails that feel hand-written. With gated_all oversight, sales reviews every element — recipient, subject, body — before any email sends, preventing wrong-person or wrong-company errors that damage sender reputation.

1

Research the Prospect

Your AI agent gathers context about each prospect — company, role, recent activity, public content, and potential needs — to find genuine personalization angles.

2

Craft Individual Messages

Using send_email, the agent drafts a unique email for each prospect that references specific, relevant details. No templates — each message feels individually written.

3

Human Reviews Everything

With gated_all oversight, every element is reviewed: Is this the right person? Is the company research accurate? Does the message tone match our brand? Sales approves before any email sends.

4

Track Engagement

The agent monitors check_inbox for replies and tracks which personalization approaches generate the highest response rates.


Try it with your agent

Pick your platform, copy the prompt, and paste it to your AI agent — it sets up MultiMail and builds the whole flow. Nothing to fill in.

1. Read https://multimail.dev/llms.txt, connect the MultiMail MCP server, create a free inbox, and set up a verified sender. 2. In HubSpot, trigger this workflow from a contact-based Workflow when a contact enters a cold outreach list, reaches a lifecycle stage like Lead, or has a custom outreach_ready property set to true; use HubSpot’s workflow webhook action or CRM API access to pass the contact and company fields to me. 3. For each contact, review their HubSpot contact record, company record, recent notes, website, role, industry, and any visible buying signal, then create a concise personalization hook and draft a natural first-touch cold email with a specific subject line. 4. Schedule a short follow-up sequence only for contacts who do not reply: one polite bump after 3 business days and one value-led follow-up after 7 business days, stopping if HubSpot shows a reply, meeting booked, unsubscribe, or disqualification. 5. Run MultiMail in gated_send mode so every recipient, subject, body, and scheduled follow-up waits for human approval before sending; ask me only for the HubSpot connection, sending-domain approval, and brand voice to go live.

What you get

5-10x Higher Response Rates

Deeply personalized emails that reference specific, relevant details consistently outperform template-based outreach by 5-10x.

Reputation Protection

Gated all oversight means every email is reviewed before sending. Wrong-person errors, factual mistakes, and off-brand messaging are caught before they damage your sender reputation.

Scale Without Sacrificing Quality

AI handles the time-intensive research and drafting. Sales reps review in seconds what would take 15 minutes to create from scratch.

Compliance Built In

Every cold email includes required CAN-SPAM elements. The AI agent handles unsubscribe links, physical address requirements, and opt-out processing.


Recommended oversight mode

Recommended
gated_all
Cold outreach carries the highest reputation risk of any email type. Wrong-person errors, inaccurate company research, or tone-deaf messaging can permanently damage your sender reputation and brand. Gated all ensures human review of every element before delivery.

Common questions

Why gated_all instead of gated_send?
Cold outreach requires reviewing the recipient as much as the content. Gated all lets sales verify that the AI targeted the right person at the right company before sending. A great email sent to the wrong person is worse than no email at all.
How does the AI find personalization angles?
Your AI agent researches prospects using public data — conference talks, blog posts, LinkedIn activity, company announcements. It identifies genuine connection points that make the email feel hand-written rather than templated.
How do we handle GDPR and CAN-SPAM compliance?
MultiMail includes unsubscribe links and honors opt-out requests automatically. For GDPR compliance, your AI agent should verify legitimate interest basis before outreach. For CASL (Canada), explicit consent may be required. The compliance tags in your contact records help the agent enforce these rules.
What response rate should we expect?
Well-researched, personalized cold emails typically see 8-15% response rates compared to 1-2% for template-based outreach. The key is genuine personalization — not just inserting a company name into a template, but referencing specific, relevant details about the prospect's work.
