Most teams never touch these. If you do, no minimum, billed against the same Stripe subscription.
Add workspaces past the included count. Each gets its own mailboxes, leads, settings, branding.
Done via our sister product ColdRelay — fresh-domain Google Workspace mailboxes, fully warmed before they hit your dashboard.
Soft-paused at quota by default. Opt-in to overage at any time — billed against current period.
For high-volume SMTP senders. Includes IP warmup and reverse-DNS setup. Generally not needed — most teams do better on Gmail.
We move your campaigns, leads, mailboxes, and webhooks from Instantly / SmartLead / Lemlist. Live in <48h.
99.99% uptime SLA, 1h-response paging, named SRE, signed MSA. Bundled with Agency tier on annual.
Instantly's market is the single-SDR running their personal pipeline. Ours is the agency running ten clients. The $149 floor filters out the noisy end of the market — which is why deliverability stays good and support stays fast. If you're not running outbound for $5k+/mo in fees, you probably want Instantly.
Soft pause by default. Active campaigns stop accepting new lead enrolments, but no email mid-sequence is dropped. You'll get a 90% / 100% notification and can opt-in to overage (at $0.30 / $0.20 / $0.10 per 1k depending on tier) or upgrade in-app.
If you opt-in to overage and never check back, we cap automatic overage at 20% of your plan quota — beyond that you must approve manually.
Yes, on Pro and Agency. Set ANTHROPIC_API_KEY in workspace settings and we use it for every draft — your spend, your rate limit. AI drafts then go from "metered against your plan" to "unmetered". Useful if you draft > 5k replies / month or want bring-your-own-model compliance.
You sit between us and your end-client. We charge you the platform fee ($50/sub-workspace/mo flat). You charge your client whatever you want — $499, $1,200, whatever. Their card runs on your connected Stripe account. We never see or hold your client's money; we never appear on their statement.
It's the same model Substack uses for paid newsletters. Full agency walkthrough →
No. 14-day full-feature trial, no card. If the trial doesn't convince you, the product won't.
Yes. Downgrade prorates immediately and we credit the difference to your next invoice. Pause keeps your data + mailboxes warm without sending for up to 60 days at $20/mo — common for seasonal businesses.
Mailboxes opt-in per-mailbox. Once enrolled, they cross-send with other mailboxes in the same tier band — Gold pairs with Silver+, Bronze pairs with Bronze + Silver, etc. Recipient mailboxes auto-mark-read, move spam → inbox, and reply ~30% of the time.
Quarantine triggers: any spam complaint, sustained bounce rate above 3%, manual flag from another customer. Quarantined mailboxes still send their campaigns but don't pair with anyone else until they're 7 days clean. Full warmup architecture →
SOC 2 Type II report: yes, available under NDA on every tier. HIPAA: no, we don't handle PHI by design — cold email isn't a healthcare workload. Signed DPA + custom MSA: included on Agency, available as add-on for Pro.
30-day money-back on first invoice, no questions. After that we'll refund unused months on annual cancellations within the first 90 days if you tell us it isn't working.
14 days, every feature, no card. If it doesn't convert your shop in two weeks, walk away — we'll even export your sequences to whatever you switch back to.
