Verified Case Study — B2B SaaS Founder

The SaaS founder who burned their
domain and what we did next.

A bootstrapped B2B SaaS founder ran two self-managed Instantly.ai campaigns without proper domain warm-up. The primary domain was blacklisted across Gmail, Outlook and Yahoo. Deligatr rebuilt the full infrastructure from scratch. 24 demo calls booked in month 3. $340K in pipeline within 90 days.

The right infrastructure was all that was missing. The ICP was good. The offer was strong. The domain was not. Deligatr fixed the one thing standing between this founder and a pipeline that worked.

What went wrong

Two failed DIY campaigns. One blacklisted domain. Zero emails reaching inboxes.

Self-managed cold email tools work when configured correctly. Most SaaS founders configure them incorrectly. Sending from a primary domain without proper warm-up, DMARC, or deliverability monitoring triggers spam filters fast. Recovery takes months. Sometimes it never fully happens.

The founder had the right ICP, the right offer, and a genuine problem to solve. None of that matters when your emails land in spam.

The primary domain was blacklisted across Gmail, Outlook and Yahoo after two poorly configured Instantly.ai campaigns without proper domain warm-up or DMARC setup.

Emails sent from the primary domain were going directly to spam for all recipients, including existing customers and investor communications.

The founder was six weeks away from a critical enterprise sales cycle and had no functional way to reach prospects by email.

LinkedIn had never been used for outbound. There was no alternative channel and no outreach infrastructure of any kind.

Investor pressure to demonstrate repeatable lead generation before the next funding conversation was increasing.

The three mistakes that blacklist domains and how Deligatr prevents them

Why DIY cold email destroys SaaS founder domains

01

Mistake: sending from primary domain

Every SaaS company needs their primary domain for product emails, investor comms and customer support. Sending cold outreach from it puts all of that at risk if blacklisting occurs. Deligatr builds separate outreach domains for every client.

02

Mistake: skipping the warm-up

New domains need 21 days of gradual, authentic sending before bulk outreach begins. Skipping this causes inbox providers to flag the domain as suspicious immediately. Deligatr runs a full warm-up protocol on every domain before a single campaign email sends.

03

Deligatr fix: full DMARC stack and monitoring

SPF, DKIM and DMARC configured on every outreach domain. Deliverability monitored daily across Gmail, Outlook and Yahoo. If a domain score drops, Deligatr rotates capacity to other domains immediately. The primary domain stays clean forever.

The Rebuild

From blacklisted domain to $340K pipeline in 90 days

The exact steps Deligatr took to recover full outbound capability from a completely blacklisted starting point, while keeping the primary domain protected.

Build
Week 1

Domain triage and isolation

Deligatr confirmed the primary domain had no viable recovery path within the required six-week timeframe before the enterprise sales cycle. Decision made to build three separate outreach domains with zero brand association to the main domain, keeping it fully isolated and protected from any further risk.

Build
Weeks 1 to 297% deliverability by Week 3

Full infrastructure rebuild

Three new outreach domains registered and warmed across nine inboxes over 21 days. Full SPF, DKIM and DMARC stack configured on every domain. Deliverability tested across Gmail, Outlook and Yahoo before any campaign sending began. Deliverability score reached 97% by end of week 3.

Build
Week 39 warm LinkedIn conversations

LinkedIn pivot during email warm-up

While email domains warmed, LinkedIn was activated targeting VP Product and Head of People at the defined enterprise ICP. Connection-first sequences generated nine warm conversations before email even went live, giving the founder active pipeline to work while infrastructure finished warming.

Build
Week 4

Email live across three ICP segments

Four-touch sequences targeting three segments simultaneously: HR tech buyers at 200 to 1,000 employee companies, COOs at Series B plus SaaS, and ops leaders at fast-growth companies with recent headcount spikes. All copy insight-led, referencing specific growth signals for each prospect.

FAQ

Questions SaaS founders ask before starting

The most common questions from B2B SaaS founders evaluating managed outbound, especially those who have already tried self-managed tools.

What happens when a SaaS founder burns their email domain with cold outreach?
When a primary domain gets blacklisted through poorly configured cold email campaigns, emails go to spam across Gmail, Outlook and Yahoo regardless of content quality. Recovery can take months and is never guaranteed. The fastest solution is building separate outreach domains with proper warm-up protocols, keeping the primary domain completely isolated. Deligatr did exactly this for the SaaS founder in this case study, restoring deliverability to 97% within three weeks.
How many demo calls did the SaaS founder book with Deligatr?
The SaaS founder booked 24 qualified demo calls in month 3 of their Deligatr campaign. Month 1 was infrastructure rebuild and domain recovery. Month 2 delivered 14 demo calls as new domains warmed and sequences were optimised. Month 3 scaled to 24 as LinkedIn was added alongside the rebuilt email infrastructure.
How do you fix a burned email domain for SaaS outreach?
Fixing a burned primary domain requires three steps. First, stop all sending from the affected domain immediately. Second, build separate outreach-specific domains that mirror your brand but carry no sending history. Third, warm these domains gradually over 21 days with low-volume authentic sending before running any cold outreach campaigns. Deligatr handles all three steps as part of the managed onboarding process.
Why did the SaaS founder choose the Deligatr Growth plan on quarterly billing?
The founder chose the Deligatr Growth plan at $4,500 per month, billed quarterly at $13,500 per quarter. Quarterly billing reduces the effective monthly rate compared to month-to-month, making it the better option for founders with a six-month outbound commitment in mind. The Growth plan includes up to 12,000 targeted prospects per month, three LinkedIn accounts managed simultaneously, and full DeliHub CRM integration with pipeline automation.
What pipeline did the SaaS founder generate with Deligatr?
$340,000 in qualified pipeline was generated within 90 days of the campaign going live. This included two enterprise deals in late-stage negotiation by end of month 3. The SaaS founder used this pipeline data in an investor update for the first time, demonstrating repeatable lead generation to their board.
