I stopped worrying about how to "save" money and focused on how I could make money.
been learning ever since
Grok Bot tip: before you send a cold campaign, have it play the spam filter. Run these 7 checks on every draft, see what lost points, then fix everything in one pass:
- Over 150 words
- Above a 4th-grade reading level
- A link, image, signature or tracking pixel
- free, guarantee, act now or $$$
- "book a call" instead of a soft ask
- An unsubscribe link where a reply-no PS should go
- A subject line over 4 words, or bait
Prompt 5 in the article scores every draft out of 100:
F*ck YES... I made a Grok Bot prompt that turns 1 cold email into 256 different emails
the shift: inbox providers stop seeing the SAME email thousands of times, and your meaning stays put
here's the 3 step guide:
step 1: give Grok Bot your 2 best drafts and spin every sentence 3-4 ways, in the format Instantly or Smartlead reads
step 2: never spin names, prices, numbers or proof, and keep every version under 150 words
step 3: have it read 10 samples as full emails and flag anything that breaks your rules
4 sentences x 4 variants = 256 emails
The full prompt is number 6 in the article:
Never put an unsubscribe link in a cold email
Put the opt-out in the PS
Ex: "PS reply no if this isn't relevant"
Every "no" still counts as a reply, and replies tell Google your emails are relevant. Then check your sending tool isn't sneaking an unsubscribe header in too
Most founders think their infrastructure is why their cold email lands in spam.
We've served 2,000+ B2B companies on Inframail, and it's usually the offer.
10 things I check before I'd ever blame the infra:
1) The offer, before the DNS records
A bad offer can ruin your deliverability and your domains.
Your offer matters more than anything.
2) Sell what it puts in their pocket
Nobody cares about getting listed on Forbes.
They care that PR can lift their close rate 20 to 40% because buyers finally trust them.
3) Buy .com or .co domains
A .com walks in wearing a suit. The cheap .xyz walks in wearing flip-flops and swim trunks.
4) Make the first line about them
"My name is John and we specialize in XYZ."
Nobody cares. Say how you help them.
5) Match the email to your landing page and LinkedIn
> people look you up before they reply
> I do it too
> no website and I'm out
> no LinkedIn and it feels risky
6) Test 7 to 10 angles every single time
Sometimes one variation beats the rest by three, four, five times.
That one cuts how many leads you need for a positive reply.
7) Drop the fake personalization
"Go tigers" because they went to that college doesn't work anymore.
People get it now.
8) Use odd numbers on purpose
"21 days" reads shorter than "3 weeks" in an inbox.
9) Give it 3 to 5 versions before you call it
Most campaigns take 3 to 5 iterations before one works.
10) Add the one line that says what they get
Ethan, one of our customers, emails homeowners. He went from half a percent to 2% replies after adding "I have an offer for you."
Then look at the infra.
(save this)
it's been a little over a month that I've been running Inframail out of London now
in celebration of my saas hitting 6 figure months
here's a day in the life
This is what Inframail taught us about how to get your first paying users:
1) the founder does the selling. Aman built Inframail and I sold it. He bet me that if I got us to 2K MRR, I'd keep all of it.
2) go where a tool like yours already has users. Our first customers came straight out of the Facebook group of a tool we connect to.
3) simple cold emails. Plain text, under 150 words, written so a 4th grader gets it. Links and images wait until they reply.
4) work backwards from your goal. 20,000 emails at a 1% reply rate is 200 replies. 20% positive is 40. 8 book a call. 1 closes.
5) most people won't reply and that's just the game. I decide if an offer works after 10,000 sends, not 500.
6) pick one niche. "B2B companies" is way too wide for one email to land with anyone. Ours was agencies already sending on Instantly or Smartlead.
7) I remove anyone who says not interested. Keep emailing them and you land in spam, then on a blacklist, then your domains are burned.
8) we took the payment on the call. Demo the product, then they pay right there. Our close rate on those calls ran 60 to 80%.
9) I track the numbers. New signups, CAC, LTV, churn and MRR are the ones I watch.
10) we sell the annual plan up front. People churn after 3, 4, 5 months on average, so the annual is what stops your month resetting to zero.
The wave of bans on the Azure tenants suck
Inframail's backend uses Azure but we do not touch tenants because they're risky
As we've seen this past week
Inframail has not been affected - if you're falsely using that in your marketing. Shame on you.
I can’t even comprehend that Adam Robinson passed away…
On the verge of tears when I heard what the fuck
Bootstrapped saas legend. I can’t believe this
the best piece of cold email advice we picked up running Inframail is the "hot dog stand"
a lot of campaigns die for the same reason:
the list
you can have the perfect copy and the perfect offer, then scrape a random list in mass and send everyone the same email
so nobody replies, and the infrastructure gets the blame
that's why I treat data like a hot dog stand: sell to people walking out of a restaurant and they're full. sell to hungry people at a football game and you can charge five times more
before every campaign I check:
- one industry
- one headcount range
- one location
- a database built for that niche (Store Leads for ecom, Outscraper for local businesses on Google Maps, Crunchbase for SaaS)
- verified right before the send, never months before
- MillionVerifier for the list, Listmint for the catch-alls
- the words that industry actually uses
- B2B. I only know a couple of people who make B2C cold email work
data should be the most expensive part of your cold email setup. it's your audience, so treat it with respect
just pick a business vertical
plumbers
roofers
chiropractors
home remodelers in Arizona
PR agencies
write one offer in their language. a plumber hears "rank when someone searches plumbing in your area", not "backlinks"
then send cold email to only them, every day, from domains named after their niche
and your marketing and your SOPs only ever have to fit one kind of client
