Connectors, AI-generated peer chats, per-ESP reputation scoring and a placement test you can re-run anytime. Tour the surface that shows up inside your workspace.
OAuth for Gmail + Microsoft 365. App password or full SMTP/IMAP for everything else. We detect the provider from your email's MX records and pre-fill the rest.
Native Gmail API integration with daily quotas of up to 2 000 sends per inbox. Watch reputation rise inside the same dashboard Google's Postmaster Tools speaks to.
Microsoft Graph API with push subscriptions for real-time delivery confirmation. SNDS / JMRP signals pulled in automatically once your tenant is connected.
Self-hosted Postfix, Mailcow, Mailu, cPanel, Plesk, Zoho — anything that speaks SMTP. Optional IMAP for full reply + folder-move behavior. Credentials envelope-encrypted with the DEK rotated quarterly.
Gmail can be green while Microsoft is red. We separate the scores so you see the gap before it shows up in your reply rate.
Separate dials for Gmail, Microsoft, Yahoo, Apple and Other. Each one updates daily from real seed-list placement and observed reply rates.
Every score plotted on a 30-day curve so you can correlate dips with template changes, ramp speed adjustments or DNS edits.
One ESP starts trending down while the others stay steady — we flag the gap and recommend the exact ramp + content tweak that closes it.
Generic warmup tools spam each other with the same paragraph. We generate full multilingual threads, reply to them, mark them as important, and move them out of Spam — the signals ESPs actually grade.
Claude Haiku + GPT-4o-mini collaborate per conversation, validated against a deliverability rubric so the content never trips a spam filter.
Real mailboxes we operate on Gmail, Outlook, Hotmail, Yahoo, Apple, AOL, Yandex, Mail.ru, Zoho, ProtonMail, GMX, Fastmail, Mailbox.org, Hey and Tutanota. Run a placement test in 60 seconds.
Pick the topics that match your real outreach (B2B SaaS, recruiting, agencies) and one or more of 9 languages. The generator stays on-brand without manual template work.
Standard ramp (5 → 50 over 9 days) for fresh inboxes. Custom ramp if you've already started elsewhere — draw your own curve in the editor.
Send only during the hours real people send. Weekends optional. Configurable per-mailbox so your APAC inboxes don't ping at 4am UTC.
Group your mailboxes — the scheduler rotates sends across the group so no single inbox ever crosses its daily cap, even during heavy ramp days.
The first thing most inboxes need is correct DNS. Our free tools generate the exact records, and the app's deliverability page tells you when one regresses.
Pick your ESP, hit copy, paste into DNS. SPF gets de-duped + lookup-cap warnings. DMARC has plain-English explanations of `p=`, `rua` and `pct`.
Every connected mailbox triggers a re-audit of its sender domain. SPF too long? DKIM missing? DMARC `none`? The dashboard tells you which one and links to the fix.
How many inboxes do you need to send X emails per day? The free calculator answers in seconds — and shows the matching domain count so you don't over-rotate.
Available on Pro and Max plans. Webhook subscriptions on Max for live reputation snapshots.
List mailboxes, pause/resume warmup, fetch the latest reputation snapshot, kick off a placement test. Per-tenant API key with role-scoped permissions.
Subscribe to reputation drops, blacklist hits, ramp milestones, or placement-test completions. Signed payloads with timestamp + nonce — replay-resistant.
Standard JSON, predictable status codes, OpenAPI 3.1 schema. Drop our endpoints into Zapier, n8n, Make or your homegrown internal automation.
Hetzner Cloud in Falkenstein, Germany. Our own /29 IP block. Optional dedicated IP on Max so your reputation is never mixed with another tenant's.
OAuth refresh tokens and SMTP passwords are envelope-encrypted with a Vault-managed KEK and a per-record DEK rotated quarterly. Nothing leaves the EU in plain text.
Every state-changing action lands in an append-only audit log, replicated to write-once storage. Right-to-export + right-to-delete out of the box.
