Huge Email Industry Dominance:
Power Features Built for Scale

Tuned specifically to deliver clean email campaigns, rotate accounts, draft with AI, and whitelist your domain—with no per-seat SaaS tax.

BYO Mailbox & ESP Rotation

Connect multiple Microsoft 365 and Gmail mailboxes via secure local OAuth PKCE. Rotate sending across 8 HTTPS API adapters (Postmark, SendGrid, Mailgun, Brevo, Resend, SparkPost, MailerSend, and SMTP2GO).

Spam Shield Sending Pacing

Paces mailboxes independently, sending one message then waiting a random 45-120 seconds to look organic to spam filters. Protects new accounts automatically with daily Warmup limit ramps.

BYO-AI HTML Email Studio

Paste your OpenAI, Anthropic, or Google Gemini API key to draft high-converting newsletters or campaigns. Smart modules can automatically improve copy, inline CSS, or fix broken markup.

Sequences & Signal Triggers

Create automated timed follow-up steps that automatically pause when recipients unsubscribe. Enroll lists automatically using trigger signals (job changes, hiring spikes, or site going live).

Domain Health & Repair List

Run client-side recipient repairs to fix domain spelling errors (e.g. `gmail.con` to `.com`) and eliminate duplicates. Audit SPF, DMARC, and MX records via DNS-over-HTTPS before sending.

Reply-To Plus Tagging

Assign individual plus-addresses (`replies+tag@yourdomain.com`) as custom Reply-To headers to identify replies and bounces programmatically—without altering your validated sender address.

SOCKS Proxy SMTP Verification

Clean email lists via real-time SMTP handshakes (HELO checks) using SOCKS proxy server integration. Validate 100,000 email addresses for just $5.00 of proxy bandwidth, preventing list decay.

The BYO Economics

Dismantling the SaaS Markup

Traditional email tools charge massive premiums on email volume and validation. Here is the actual math when you Bring Your Own infrastructure.

BYO Mailbox Economics

Connect standard Microsoft or Google consumer accounts to scale your outreach:

  • M365 Business (Domain) $5.00/mo (10k/day)
  • Personal/Business Gmail Free to connect
No Send Caps: Mailchimp caps how many times you can email your list (e.g. 10x-12x list size/mo). With us, send as many times as you want!

Email Validation Rip-Off

Verifying cold lists is essential to protect domain health. Stop paying inflated per-credit charges:
