Cold email campaigns.
Free forever — no catches.
Campaigner sends every campaign through your own Microsoft 365 or Gmail account — rotating across your mailboxes, pacing to limits your provider actually tolerates, with unsubscribe and CAN-SPAM compliance enforced by the product. No shared IPs, so nobody else's spam can wreck your deliverability.
No shared SMTP fleet. No shared sending IPs. Your domain, your reputation.
How it works
Three steps to your first campaign.
Connect your mailboxes
Sign in with Microsoft 365 (Gmail to follow). OAuth only — we never see your password. Set a daily cap, a Reply-To, and a signature per mailbox.
Bring your contacts
Import a CSV with a template, column mapping, dedupe, and an error report. Add custom fields, tags, and groups. Your do-not-contact list is enforced from the first send.
Launch, and let it pace itself
The campaign rotates across your mailboxes inside your budgets and sending windows, with randomized gaps between sends. It auto-pauses if bounces spike.
Why your own mailbox
The model is the product. Everything else follows from it.
No shared IPs, ever
We don't operate a shared SMTP fleet, so another customer's spam can never poison your deliverability. On a shared-IP ESP, it can.
Native by default
It looks native because it is — a normal message from your account. It lands in your Sent Items, threads properly, and replies come to your inbox.
Paced to your provider
Microsoft 365 publishes ~10,000 recipients/day and Google Workspace ~2,000 — but the safe working volume is far lower. Conservative caps ship by default, with randomized intervals, timezone windows, and quiet hours.
Rotation, not cap-raising
Scale by adding mailboxes with per-mailbox budgets — the sanctioned way. Raise a cap and the product warns you loudly.
Bounce spike? Auto-pause
NDR scanning detects bounces and pauses the campaign before it hurts you.
Your own database
A dedicated database per customer — not a shared multi-tenant table with a customer_id column. Your data is physically separate.
Everything in Campaigner
The whole toolkit — included on every plan, free and paid. Tiers change the limits, not the features.
Sending & deliverability
- ✓Multi-mailbox sending — connect several accounts; campaigns rotate recipients across them with per-mailbox budgets.
- ✓Custom Reply-To per mailbox and per campaign — send from many, collect replies in one place.
- ✓Human-like pacing — randomized send intervals, hourly and daily caps.
- ✓Timezone-aware windows, quiet hours, and weekend/holiday skip.
- ✓Mailbox warm-up — included on every plan, so new mailboxes ramp up safely and build sending reputation.
- ✓NDR bounce detection that auto-pauses a campaign on a bounce spike.
- ✓Plain-text "personal" mode — no HTML, no pixel — for the best cold deliverability.
Contacts & lists
- ✓Contact management with custom fields, tags, groups, and saved segments.
- ✓CSV import with a downloadable template, column mapping, dedupe, and an error report.
- ✓Per-contact activity timeline — every send, open, click, reply, and bounce.
- ✓Do-not-contact domain list — skip existing clients, competitors, or anyone you choose.
- ✓Authoritative suppression list, checked before every single send and surviving re-imports.
Campaigns & content
- ✓Template editor with a starter library and one-click cloning.
- ✓Merge fields with fallbacks —
Hi {{FirstName|there}}— plus reusable snippets and signatures. - ✓Meeting-link merge field — drop your Calendly or Bookings link into any message.
- ✓Test send before launch — required, so nothing goes out unrendered.
- ✓Attachments per campaign, with deliverability warnings for cold outreach.
Analytics & team
- ✓Campaign reports — sent, opens, clicks, bounces, replies, unsubscribes, with a per-mailbox breakdown.
- ✓Account dashboard — deliverability health, sends this month, list growth.
- ✓Multi-user roles — Owner, Admin, Editor, Viewer.
- ✓Notifications for campaign done, mailbox disconnected, import complete, and health warnings.
- ✓Audit log of sends, suppressions, imports, and mailbox connections.
The compliance is the product.
Built in, not bolted on — because with cold outreach it's the part that costs you your domain if you get it wrong.
- ✓Visible unsubscribe in every marketing email, with suppression that takes effect immediately.
- ✓RFC 8058 one-click unsubscribe (
List-Unsubscribe+List-Unsubscribe-Post) — required by the Google/Yahoo bulk-sender rules, and honored in seconds rather than the mandated two days. - ✓CAN-SPAM physical address auto-injected into the footer — the product blocks a send without a compliant footer.
- ✓Consent source and timestamp recorded on every contact, for GDPR and CASL readiness.
- ✓Per-contact data export and a right-to-erasure flow that keeps a suppressed email hash — so an erased person can never be re-imported and re-emailed.
- ✓The suppression list is authoritative and permanent — checked before every single send, and it survives re-imports.
A do-not-contact is forever. Re-import the same list tomorrow and we still won't email them.
Start free. Scale when you're ready.
Every plan includes the complete Campaigner toolkit. Paid plans just raise the limits — more contacts, mailboxes, sends, and users. The features never sit behind a paywall.
Annual billing is 10× the monthly price — two months free.

Start on the Free Forever plan — no credit card required. Create your account →
Why start free? Because the sending happens through your own mailbox — we don't run a shared SMTP fleet, so the free plan costs us almost nothing to offer, forever. It's the complete product, not a trial. Paid plans don't unlock features — they raise the volume limits (contacts, mailboxes, sends, and users) for teams that outgrow the free tier. Some advanced add-ons listed under "After launch" may be paid when they arrive.
After launch
These are planned, not built, and not promised for a date. They are not part of the product today.
