Deliverability and inbox warmup

Set up your domain first

Before any cold sending, configure SPF, DKIM, and DMARC DNS records for your sending domain (your email provider documents the exact records). Without them, even perfect emails go to spam.

Warmup

Enable warmup per mailbox in Dashboard → Email Accounts. Warmed mailboxes exchange friendly traffic on a schedule that builds sender reputation. Give a brand-new mailbox 2–3 weeks of warmup before meaningful volume.

The rules that keep you safe

• Keep daily limits realistic: 20–30/day for new mailboxes, ramping to 50–100 over weeks.
• Verify every list before sending (target < 2% bounce rate).
• Rotate across multiple mailboxes rather than maxing out one.
• Personalized, plain-looking emails (which agents write by default) outperform image-heavy templates in both replies and inbox placement.
• Every email carries a one-click unsubscribe automatically — never remove it.

Reading the dashboard

Dashboard → Deliverability shows health per mailbox and per domain: sent, bounces, opens, replies. A falling open rate or rising bounce rate on one mailbox means: pause it, lower its limit, re-verify the list, and let warmup run.
