Deliverability‑First Growth: More Landings Before More Leads
Every time someone tells me they “need more leads,” my first question is: “How many of your existing emails actually land?” Not open, not click—land. If you’re burning 30–40% of your sends in spam, another lead source won’t save you. It will just waste money faster. Deliverability is not a Folderly problem. It’s a growth problem.

Deliverability‑First Growth: More Landings Before More Leads
Most teams try to fix the pipeline by “getting more leads.” If 30–40% of your emails don’t land, you’re scaling a leak. This is how I think about deliverability as a growth lever, not a technical chore.
1. The invisible tax on your pipeline
Deliverability is a quiet tax:
You don’t see the people who never got your message
You only see “low replies” and “low open rates”
If 30% of your emails don’t land:
Your CAC is instantly higher
Your test cycles are slower
Your team loses confidence in outbound
You’re not doing “bad outbound.” You’re doing invisible outbound.
2. The growth equation nobody writes down
Most teams think in terms of:
Replies = Leads = Meetings = Revenue
But the real equation is:
Revenue = (Delivered × Opened × Replied × Qualified × Closed)
Deliverability is the first multiplier. If that number is broken, the rest of your funnel math is a lie.
3. The “Deliverability‑First” stack in plain English
If I had to make one simple stack for any team, it would be:
Healthy domains
Multiple sending domains
Proper DNS (SPF, DKIM, DMARC)
Human‑like sending volumes
Warm‑up & reputation guardrails
Gradual ramp‑up on new domains
Daily caps per inbox
Alerts when bounce or spam signals spike
Clean lists, always
No buying giant lists
Real‑time validation on form fills
Regular pruning of dead or inactive contacts
Message patterns ISPs actually like
Short, plain emails
Low link / image usage in first touch
No spammy subject line tricks
None of this is sexy. All of this is cheaper than burning a domain (and your funnel) every quarter.
4. Deliverability as a product decision
Here’s the part most people miss: deliverability isn’t just about your emails. It’s about your promises.
If your messaging forces you into:
Overhyped claims
Misaligned targeting
Aggressive follow‑up
…you will inevitably get more spam complaints, which will kill your domain.
The more your product actually delivers:
The fewer people mark you as spam
The more positive engagement you generate
The better your long‑term reputation with inbox providers
Better product → better word of mouth → better deliverability. That loop is real.
5. A simple “deliverability health” scoreboard
Instead of obsessing over open rate, I’d track:
Bounce rate: keep it under ~2%
Spam complaint rate: keep it below 0.1%
Inbox placement tests: what % of tests land in primary / promotions vs spam
Domain “lifespan”: how long can a domain stay healthy at current volumes
And I’d review it weekly, not when the damage is already done.
6. Putting it into practice in 30 days
A 30‑day deliverability‑first sprint could look like:
Week 1: Audit domains, DNS, sending patterns
Week 2: Clean lists, kill bad data sources
Week 3: Rewrite templates to be shorter, simpler, and more honest
Week 4: Set up monitoring + new sending rules
You don’t need perfect. You need to stop paying an invisible tax forever.
7. Deliverability checklist for founders
Before you ask for “more leads,” ask:
Do we know our real deliverability across main domains?
Are bounce and complaint rates monitored weekly?
Are we pruning low‑engagement contacts regularly?
Does our product actually support the promises in our email copy?
If inbox providers could “review” us like users, would we pass?
Once these boxes are ticked, then go buy more traffic.
