New domain launch

Your new domain has zero reputation. Receivers assume the worst.

Mailbox providers distrust fresh domains by default, and a first campaign sent cold can bury you in Spam before you have a history to argue with. Launch the way the big senders do: correct DNS on day one, an automated ramp, and placement proof before real volume.

The launch playbook

Five steps from fresh registration to first campaign.

Step 1

Publish authentication on day one

Guided DNS generates SPF, DKIM and DMARC for your setup, live-verifies each record, and publishes in one click to Cloudflare, GoDaddy, Name.com or Dynadot. Correct auth from the first message is the cheapest reputation you will ever earn.

Step 2

Let Inbox Boost build the history

The automated ramp sends jittered daily volumes inside your sending windows and timezone, weekdays-only if you prefer, with AI-written per-vertical content. A seed network answers with real opens, clicks and replies, and a bounce-rate guard auto-pauses the ramp if anything looks off. Entry schedules ramp to 250 a day; the top tier to 3,000.

Step 3

Test placement before real campaigns

Send placement tests from your own SMTP to seeds across Gmail, Workspace, M365, Yahoo, Zoho and AOL. You get folder-level results, Primary, Promotions, Spam or missing, plus per-seed SPF, DKIM and DMARC, and you can re-check as the ramp progresses.

Step 4

Monitor from day one

The domain gets its full scan across 48 blacklist and reputation sources the moment you add it, then scheduled rechecks from daily to every 15 minutes by plan. The 0-100 score and trend history show the reputation curve as it builds, and Google Postmaster charts Gmail's own view.

Step 5

Wire alerts before you need them

Route score drops, new listings and auth failures to email, Slack or an HMAC-signed webhook, with rules, routing and cooldowns. A young domain has no reputation cushion, so you want to hear about a regression the moment it happens.

  • Start on the free tier: first domain, no card required
  • Use a sending subdomain and monitor it as its own asset with its own score
  • Re-run placement tests at each ramp milestone to see the curve bend
  • Deliverability checks included in the 30-day trial: SPF, DKIM, DMARC, PTR, TLS and MX, hourly by default

Plan your ramp

How fast can this domain get to volume?

Drag the slider to your target daily volume and see where the plan schedules take you.

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

New domain questions, answered.

How long until my new domain is ready to send for real?
Honestly: it depends on your volume goals. Inbox Boost ramp schedules run on plan-based day counts, entry schedules ramp to 250 messages per day and the top tier to 3,000 per day. A domain that needs to send a few hundred a day is ready sooner than one that needs thousands. Placement tests are the readiness check: when your mail lands in Primary across providers, you are ready.
Can I skip the ramp and just start sending?
You can, nothing stops you. But run a placement test first: fresh domains with zero history usually land in Spam or go missing at major providers, and that test tends to make the case for ramping better than we can. Digging a new domain out of a bad first impression is slower than building the reputation properly.
Do I need a subdomain strategy?
Usually, yes. Keeping campaign mail on a dedicated sending subdomain (for example mail.yourbrand.com) isolates its reputation from your root domain. SenderSignal monitors domains and subdomains as separate assets, each with its own score and trend history, and guided DNS sets up each one correctly.
What does Inbox Boost actually do?
First it gets DNS right: generate SPF, DKIM and DMARC, live-verify, and publish in one click to Cloudflare, GoDaddy, Name.com or Dynadot. Then an automated ramp sends AI-written, per-vertical content on jittered daily volumes within your sending windows and timezone (weekdays-only if you want), and a seed network supplies real engagement: opens, clicks and replies. If bounce rates climb, the ramp auto-pauses. Usage draws on monthly credits.
How do I know the ramp is working?
Watch the signals, not the promises. Your 0-100 reputation score with trend history shows the trajectory, the Google Postmaster integration charts Gmail domain reputation and spam rate in-app, and credit-metered placement tests show folder-level results across Gmail, Workspace, M365, Yahoo, Zoho and AOL, with re-checks supported as the ramp progresses.
