Cold email automation with AI
AI writes personalized cold emails from your brief, sends them via your own SMTP, and replies to every response — 24 hours a day.
Your own SMTP
Connect Gmail, Outlook, or any SMTP. Emails come from you, not a shared server — protecting your sender reputation.
28-day automatic warmup
Orbitra runs a gradual warmup before your first outreach email, building sender trust step by step.
AI reply agent
When prospects reply, the AI reads the context and responds automatically in your tone, toward your goal.
Open tracking
Track email opens with a 1×1 pixel. See which prospects engaged and when, per campaign.
The 28-day warmup — built in, automatic
Email providers flag accounts that suddenly start sending 60 cold emails/day from a fresh address. Orbitra's warmup system ramps up gradually over 28 days, teaching email providers to trust your sender address before full outreach volume begins.
Ramp start
Days 1–7
20 emails/day
Building trust
Days 8–14
35 emails/day
Mid-warmup
Days 15–21
50 emails/day
Full send
Days 22–28
65 emails/day
Daily limits are enforced automatically. Orbitra never exceeds your configured limit, and you can reset the daily counter manually from the account settings.
How the AI writes cold emails
Before launching a campaign, you write a brief: your product or service, the pain point you solve, your ICP (ideal customer), common objections, and the goal of the campaign (e.g. "book a 30-min call"). Orbitra's AI uses this brief to write every email from scratch — not a template with variables, but a real email calibrated for each lead.
Sharp, direct opener
Addresses the lead's pain point in the first sentence — no fluff, no 'hope this email finds you well'.
No AI clichés, ever
Forbidden phrases are enforced automatically. If the AI writes something generic, it's rejected and regenerated.
Signed as you
Every email is signed with your name and job title from your profile — not a tool signature.
Tone calibrated for email
Slightly more formal than LinkedIn DMs, always conversational — never corporate, never pushy.
Follow-ups that vary
Each follow-up in the same thread uses a different angle — never the same copy pasted twice.
Brief-driven, not template-driven
The AI generates each message from scratch using your campaign brief — not a template with {{variables}}.
The AI reply agent for cold email
When a prospect replies — whether positively, with an objection, or just a question — Orbitra's AI agent reads the full conversation context and replies appropriately. It never sends the same follow-up script twice. It adapts based on what the prospect said.
The reply happens with a random 10–60 minute delay to simulate natural human behavior. You can set each lead to Automatic (AI sends without review), Guided (AI drafts, you approve), or Manual (you reply yourself).
Open tracking
Every email includes a 1×1 pixel that fires when the email is opened. Orbitra records the first open timestamp per lead and updates campaign open rate metrics in real time.
Known limitations
- • Gmail prefetches images — tracking may fire before the user opens
- • Proton Mail blocks tracking pixels — opens from Proton users won't register
- • Open rate is a directional metric, not a precise count
