How most cold emailers clean their lead lists:

1. Export their contact list
2. Upload it to a verification tool
3. Wait
4. Download the results
5. Re-import the clean list
6. Suppress the bounces

That's 2+ hours per week.

8 hours per month.

Almost 100 hours per year.

On something that should take 0 minutes.

And don't get me started if you do crazy sales volume.

I switched to Bouncer AutoClean since it came out.

It: 

1. Connects to your CRM.
2. Verifies new contacts every hour.
3. Reverifies existing ones automatically.
4. Suppresses undeliverable emails on its own.

I haven't touched a verification CSV since.

And my bounce rate has been as low as ever.

Automate the boring stuff.

Spend your time on what actually makes you money.

Landing 1.2M+ cold emails/month in the inbox at Grow Surely

I check 6 things before sending any sales email campaign.

(Skipping even one can destroy your deliverability)

1. DNS setup → MxToolBox

SPF, DKIM, DMARC must be perfect.

If anything is in red, I let the domain warm up for longer.

No exceptions.

2. Domain reputation → Cisco Talos

If a domain's reputation isn't perfect, nothing is sent from it.

3. Email verification → Bouncer

Every email gets verified before it touches a campaign.

It also identifies spam traps, breached addresses, and complainers.

Invalid/untrusted emails = bounces = reputation damage.

4. Copy readability → Hemingway Editor

Grade 7 reading level or below.

If a 14-year-old can't understand it, simplify it.

5. Mailbox warm-up → Instantly.ai

Every mailbox needs at least 14 days of warm up.

I also always leave backup inboxes to warm up for longer.

6. Sequencing → Instantly.ai

Randomized times. Random intervals.

Predictable patterns trigger spam filters.

That's it.

6 checks. <15 minutes. Every campaign.

I track a metric that most cold emailers ignore.

It's not reply rate.

It's not open rate.

It's lead-to-valid-email rate.

Here's what I mean:

You build a list of 1,000 leads.

You run them through an email finder.

Only 400 come back with valid emails.

That's a 40% lead-to-valid-email rate.

Which means 60% of your research was wasted.

I used to deal with this every week.

Hours spent building lists.

Half the leads had no usable contact info.

It was the most frustrating bottleneck in my workflow.

Then I switched how I source leads.

I start with Prospeo.io 

And it's not just for enrichment.

But for the entire list build.

Here's why it changes everything:

→ 280M+ contacts with pre-verified emails
→ I filter by ICP before I ever export
→ Every email is verified at the source
→ My lead-to-valid-email rate went from 40% to 90%+

That means from 1,000 leads, I get 900+ valid emails.

Not 400.

Same effort. More than double the output.

Here's what that looks like in practice:
Old workflow:

→ Scrape leads from 3 different tools
→ Cross-reference in Clay
→ Run emails through a verifier
→ Lose 50-60% of the list
→ 4 hours of work for 400 usable leads

New workflow:

→ Build the list directly in Prospeo
→ Enrich for personalization
→ Push to Instantly.ai
→ few minutes for 900+ usable leads

The best campaigns don't start with better copy.

They start with better data.

If you're losing half your list before you even send, fix the source.

You don't need to hire more people.

You just need better AI tools.

Most B2B founders think scaling means adding headcount.

More SDRs, more researchers, more coordinators.

But here's what happens:

- Higher payroll costs.
- Training nightmares.
- Inconsistent results.

And you're still not hitting your targets.

There's a better way.

AI can do the work of 5 people for the cost of 1.

1. It researches prospects faster than any human.
2. Finds verified emails in seconds.
3. Personalizes outreach at a massive scale.

Never takes a sick day or asks for a raise.

The difference?

Some of our clients used to have teams of 8 doing manual outreach.

Now they just have us, using the right AI tools.

Better results, 80% lower costs.

Because smart founders don't just work harder.

They replace repetitive tasks with intelligent automation.

Check the infographic below for 10 AI tools that can replace entire departments.

P.S. What's the first role you'd replace with AI?

Co-Founder @ Grow Surely ($1.5M ARR) | Helped 100+ B2B companies scale with outbound

This mistake is ruining your outbound strategy

(and draining your motivation)

Focusing on outcomes instead of the process.

- “We need 10 new clients ASAP.”
- “We need an extra 20K MRR next month.”
- “We want a 20% increase in calls booked.”

Those are solid objectives. You need them.

But you can’t leave the meeting without a plan.

Objectives → Action Plan → Execution

Without a clear roadmap, you’ll:

Try every new ‘hack’ you read about.

Jump between tactics without tracking anything.

End up not knowing which part is actually broken:

Offer, messaging, or something else.

So here’s my advice if your goal is to get new clients:

Break it down.

For example, if your goal is to get 10 clients:

- Send 10,000 emails
- Aim for a 2.5% reply rate
- Convert 20% of replies into calls
- Convert 20% of calls into clients
- Get 10 clients

Map the steps.

Execute the plan.

Track everything.

And if you need the right frameworks, I’m here to help.

This is the future of B2B sales.

P.S. Which part of your GTM strategy takes the most manual work?

I asked 40+ CEOs which cold emails they respond to.

Here's what came up the most:

- Emails that understand their pain points
- Emails that show success with similar clients
- Emails that give relevant examples

So, for your next cold email, ask:

- Which pain point does this email address?
- Which similar clients have we worked with?
- Does this example match their pain point?

You’ll get more and better meetings.

Follow for more.

Everyone talks about "personalization" in cold email.

(But they're doing it all wrong)

They personalize the message.

But ignore who they're messaging.

Real personalization starts before you write a single word.

It starts with who you're targeting.

I used to obsess over perfect email copy.

While sending it to terrible prospects.

Then I flipped my approach.

I started personalizing my prospect list first.

Here's how:

Step 1: Cast a wide net

- Use basic filters in Clay.
- Industry, company size, location.
- Don't overthink this part.

Step 2: Let AI qualify every company

- AI visits each company website/description.
- Asks one question: "Do they fit my ICP?"
- Simple yes or no answer.

Step 3: Keep only the "yes" companies

- Filter out everything else.
- Now you have a laser-focused company list.

Step 4: Find the right contacts

- Job titles, seniority, experience.
- The people who actually make decisions.

Step 5: Score, enrich, and validate

- Clay lets you enrich with any data point.
- Build variables for meaningful personalization.
- Get creative here.
- This creates the foundation for emails that convert.

Remember: 

The best email copy can't save bad targeting.

But good targeting can save average copy.

How to create hyper-targeted lead lists with Clay

1 in 3 prospects never see your emails.

Here’s how to fix it in 60 seconds:

Your email tool flags catch-all domains as “risky” and tells you to skip them.

But here’s the truth:

You’re losing 30% of your TAM.

Because 1/3 of your dream clients use catch-all emails.

And you’re ignoring them.

Here’s what happens when you skip catch-all emails:

- You delete prospects who would’ve replied.
- ⁠You shrink your lead pool before hitting “send.”
- You leave money on the table for competitors.

Now don’t forget:

We still need to keep bounce rate as low as possible.

This is why I use Icypeas:

- Verifies catch-all emails
- Reaches real people others skip.
- Reduces bounces to <1%
- Protects sender reputation.

The math is simple:

More verified emails = More replies = More closed deals.

Especially critical for small teams.

You can’t afford to miss 30% of your TAM.

What's working for SaaS cold email in 2026:

(We sent 1M+ emails to figure this out)

No demos. No sales calls.

Just driving free trial signups directly.

Here's what we're seeing:

The best-performing emails are embarrassingly simple.

One sentence of value. One CTA. No links.

"We built a tool that does X. It's free. Reply YES and I'll send you the link."

That's it.

Your product needs to do the selling.

Not your sales team.

And if you don't have a free version to offer cold traffic?

You're making it 10x harder than it needs to be.

The buying decision happens inside the product.

Not on a call.

P.S. Still think cold email doesn't work for SaaS?
