For cold outreach

New domains burn fast. Ramp before you launch.

A fresh domain with no sending reputation and a thousand-contact sequence is how outreach domains die. SenderSignal ramps each new domain with real engagement, tests placement before you hit send, and watches for listings while the campaign is in flight.

The outreach playbook

Every new domain follows the same safe path.

DNS done right on day one

Guided setup generates SPF, DKIM and DMARC and can publish records straight to Cloudflare, GoDaddy, Name.com or Dynadot, for the sending domain and the tracking domain alike. Broken auth is the fastest route to the spam folder; fix it before the first send.

Automated ramp with real engagement

Inbox Boost sends jittered daily volumes inside your timezone's sending windows (weekdays-only if you want), earning genuine opens, clicks and replies across a seed network. Entry schedules ramp to 250 a day; top-tier schedules reach 3, 000.

Placement test before every sequence

Send a test from your own SMTP to seeds across Gmail, Workspace, M365, Yahoo, Zoho and AOL and see the folder it lands in, Primary, Promotions or Spam, plus per-seed auth results. If it lands in Spam, you fix that before a thousand prospects confirm it.

Catch listings mid-campaign

48 blacklist and reputation sources, rechecked as often as every 15 minutes on the top tier, with score-drop alerts to email, Slack or a signed webhook. Pause the sequence while the domain is still salvageable.

  • Bounce-rate auto-pause stops a ramp before a bad list kills the domain
  • Extra assets and Inbox Boost slots à la carte, scale domain by domain
  • Bulk import the whole domain fleet; every asset gets an initial scan immediately
  • Manual rescan any domain right before a launch for a fresh all-clear

Plan your ramp

From fresh domain to sending volume.

Drag the slider to your target daily volume and see which ramp stage gets you there.

500 emails/day
Entry schedule (to 250/day)

Tops out at 250/day. For 500/day you want a higher tier.

Top-tier schedule (to 3,000/day)

Reaches your target at stage 4 of 10.

Stage volumes follow your plan's ramp schedule with natural day-to-day variation, inside your sending window, with an automatic pause if bounces rise. Top-tier bars are illustrative spacing within the real 100 to 3,000/day range.

Questions

Cold outreach questions, answered.

How long before a brand-new domain is ready for campaigns?
Inbox Boost runs an automated ramp: jittered daily volumes inside sending windows you set (with a weekdays-only option), climbing to 250 emails a day on entry schedules and up to 3, 000 a day on the top tier. The engagement is real, opens, clicks and replies across a seed network, and the content is AI-written for your vertical.
What stops a bad list from torching the domain mid-ramp?
Bounce-rate auto-pause. If bounces spike, the ramp stops automatically instead of grinding the domain’s reputation down while you sleep. Restart when the list is cleaned.
Can I check where my emails actually land before a big sequence?
Yes, inbox placement tests send from your own SMTP (presets for Gmail, M365, Yahoo and Zoho) to seed inboxes across Gmail, Google Workspace, M365, Yahoo, Zoho and AOL. You get folder-level results, Primary, Promotions, Spam, plus per-seed SPF, DKIM and DMARC outcomes. Tests are credit-metered, so you pay per run.
Cold outreach means lots of small domains. Does that get expensive?
Your first domain is free with no card, and extra assets and Inbox Boost slots are à la carte, so a fleet of small outreach domains scales by the domain, not by forcing you up a plan tier. Bulk import gets the whole list scanned in one go.
A domain got listed while a campaign was in flight. When would I have known?
On the top tier, scheduled rechecks run every 15 minutes across 48 blacklist and reputation sources, and a score-drop alert fires to email, Slack or a signed webhook. That is the difference between pausing a sequence at step two and burning the domain by step six.
