Quick answer
What is cold email infrastructure?
Cold email infrastructure is the sending layer underneath any outbound campaign: the mailboxes you send from, the warmup that builds their reputation, the DNS records (SPF, DKIM, DMARC) that authenticate them, and the deliverability monitoring that keeps you out of spam. Done badly, it tanks every campaign no matter how good the copy. Scrupp handles it for you: grab pre-warmed inboxes that are ready to send, or connect your own Gmail and Outlook in one click — then auto-warmup, sending limits, and a 24/7 deliverability agent run in the background. No separate domain registrar, no warmup subscription, no DNS spreadsheet.
Features
Everything between “new domain” and “first reply”
The plumbing that decides whether your emails get seen — inboxes, warmup, authentication, and monitoring, all in one place.
Pre-warmed inboxes
Ready-to-send mailboxes that are already warmed — from $9.99 with $0 setup. Skip the weeks of warming a brand-new domain before you can send.
One-click Gmail & Outlook
Connect your existing Google Workspace or Microsoft 365 mailboxes with OAuth — no IMAP settings, no app passwords. They become sending inboxes instantly.
Automatic warmup
Every inbox warms itself on autopilot, ramping volume gradually to build reputation. New domains can opt into fast-start to begin sending sooner.
24/7 deliverability agent
Continuously checks SPF, DKIM, and DMARC plus seed-inbox placement, and rolls it into one health score — so you catch problems before they sink a campaign.
Spread sends across multiple mailboxes with per-inbox daily caps that respect each one’s warmup stage — scale volume without burning a domain.
SPF, DKIM, and DMARC are set up and verified for you — no copy-pasting DNS records or guessing whether authentication actually passed.
Why it’s different
One subscription, not five
Most teams pay separately for a domain registrar, mailboxes, a warmup tool, a verifier, and a sender. Scrupp folds infrastructure into the same plan as scraping, enrichment, and sending.
- Domain registrar — separate bill
- Mailbox provider — separate bill
- Warmup tool — separate bill
- Email verifier — separate bill
- Sending tool — separate bill
- Pre-warmed inboxes from $9.99
- Warmup & deliverability included
- Scraping & enrichment in the same plan
- Campaigns & AI inbox in the same plan
- One login, one bill, one workflow

Domains, DNS, warmup, and sending limits are handled by default and shown to you as confirmation that they’re set up — never as required input on the critical path. You can open “Advanced” to fine-tune any of it, but you never have to.
FAQ
Common questions
What are pre-warmed inboxes?
They’re mailboxes that have already gone through a warmup period, so they have sending reputation from day one. Instead of waiting weeks before a fresh domain can safely send cold email, you start with inboxes that are ready to go — from $9.99 with no setup fee.
Can I use my own Gmail or Outlook?
Yes. Connect Google Workspace or Microsoft 365 mailboxes in one click with OAuth — no IMAP configuration or app passwords. Once connected, they become sending inboxes with warmup and deliverability monitoring applied automatically.
Do I have to set up SPF, DKIM, and DMARC myself?
No. Authentication is set up and verified for you, and the deliverability agent keeps checking it 24/7. You see a single health score rather than a pile of DNS records to debug.
How is this different from Instantly or Smartlead?
Those tools sell sending and warmup, then you bolt on a separate scraper, enrichment, and verifier. Scrupp gives you the inboxes, warmup, and deliverability plus B2B lead scraping, phone enrichment, and a unified inbox in one subscription. Deliverability monitoring is included rather than a paid add-on.
How many inboxes do I need?
It depends on your daily volume. Each inbox sends a safe capped number per day, so teams spread volume across several mailboxes with automatic rotation. Start with a few and add more as your campaigns scale — limits ramp with warmup so you never over-send.
