The most dangerous DNS mistakes aren’t the obvious ones.

They’re the ones quietly damaging your email deliverability in the background:

• Incorrect SPF records
• Outdated DKIM keys
• Missing DMARC policies
• Forgotten or conflicting DNS entries

One weak record can affect your entire sending reputation.

Your domain is only as strong as its weakest configuration.

Your SPF record has a limit most people don't know about.

Maximum 10 DNS lookups. Exceed it → SPF fails → your emails get flagged.

Every service you add (Mailchimp, HubSpot, Salesforce…) counts toward that limit.

Cold email isn't dead.

Bad cold email is dead.

And there's a massive difference.

AI made it easier to send more emails.
Lazy senders flooded inboxes with generic templates.
Gmail got smarter. Filters got stricter.
Bad emails stopped landing.

And everyone concluded cold email was dead.

Wrong. They just got filtered out.

The best sales teams don't send 10,000 emails a week.
They send 200.
Carefully crafted. Perfectly targeted.
Verified list. Flawless sender reputation.

And they book more meetings than the ones sending 10,000.

Cold email in 2026 rewards one thing.

Respect.

The ones who get this right aren't complaining.
They're closing deals. 🥷

AI won't kill email marketing. It'll make it 10x more powerful.

And 10x more demanding.

More volume. Smarter filters. Reputation more critical than ever.

AI amplifies what already exists. The good… and the bad.

A clean list is still the only real foundation. 🥷

Most people think lead generation is a volume game.

More scraping.
More emails.
More sequences.

Wrong.

Here's what actually happens when your list is dirty :

→ 1 out of 5 addresses doesn't exist
→ Every bounce damages your sender reputation
→ Gmail and Outlook start filtering your emails
→ Even your good emails stop landing

You don't have a volume problem.
You have a quality problem.

The best growth teams in 2026 verify every address before importing it into their ESP.

Before the sequence.
Before the campaign.
Before hitting send.

Invalid addresses removed.
Spam traps eliminated.
Bounce rate below 0.1%.

You don't change your strategy.
You change your foundation.
And your results do the rest.

You spent hours writing the perfect email.

Great subject line. Strong copy. Clear CTA.

It went straight to spam.

All that work. Zero impact.
This is what poor deliverability costs you.

Everyone talks about subject lines, design,
segmentation.

Almost nobody talks about the infrastructure that gets
all of it delivered.

Deliverability is the foundation.
Without it, everything else is pointless.

#EmailDeliverability

[MailTester.Ninja 🎯 @MailTesterNinja]

You hit "Send."

Perfect copy. Perfect offer. Perfect timing.
And you just made the biggest mistake of your email strategy.

Because your list isn't clean.
→ Dead addresses
→ Spam traps
→ Invalid domains

Invisible to the eye. Devastating for your reputation.
Bounce rate explodes. Gmail takes note. Sender reputation drops.

Your next emails even the good ones land in spam.

You never see it coming. It happens in silence.

A clean list doesn't guarantee success.

But a dirty list guarantees failure.
Verify before you send.

The SPF / DKIM / DMARC trio explained simply
If you send professional emails, this thread is for you.

SPF → whitelist of your sending servers

DKIM → cryptographic signature of your emails

DMARC → policy if SPF or DKIM fail

All together = a trusted email infrastructure.

SPF, DKIM, DMARC.

Three acronyms 90% of marketers know by name.
And 10% actually know how to configure.

The gap between the two ? Emails that never arrive.

#EmailMarketing

[MailTester.Ninja 🎯 @MailTesterNinja]

DKIM = a digital signature inside every email you
send.

It proves the email genuinely comes from you and
wasn't altered in transit.

Without DKIM :
■ Less trust from recipient servers
■ Phishing risk associated with your domain
■ Degraded deliverability

How do you end up on a blacklist ?

→ Too many spam complaints
→ An unusual sending spike
→ A poorly cleaned email list
→ A compromised old IP

Most of the time it's not a mistake. It's negligence.
