  1. Warming up email accounts
  1. Getting the right email accounts
  1. Making sure your domains are setup the right away
  1. Lead Verification
  1. Sending volume per day
  1. Using Spintax
  1. What not to put in your cold emails.
  1. Open Rate & Link Tracking
  1. Email signatures
  1. Sending cold emails that just don't suck
1. Warming Up Email Accounts
You will be using some sort of sending software (Smartlead, Instantly, etc.) to send REAL LOOKING cold emails back and forth.
Warming essentially means sending real looking emails to other email accounts so they build up activity and a track record of not spamming people.

Inside of Smartlead & Instantly, they put your accounts inside a warmup pool with other peoples accounts to do this.
Below are the warmup settings we use for all clients across the boardπŸ‘‡:
  • Total number of warm up emails per day β†’ 35
  • Daily Rampup β†’ 4 per day
  • Randomize number of warmup emails sent per day β†’ 25-35
  • Reply Rate β†’ 35%
Now, lets go over what each of these settings do:
Total number of warmup per day - This is the total number of warmup emails each account will send per day.
Daily Rampup - This is a MUST! -You can't just create an email account and max out the volume, you need to scale it over time.
Randomize number of warm up emails sent per day - This one is simple, no human sends the same amount of emails every single day, but there will be an approximate range. This randomizes it so it looks natural and real.
Reply Rate - Another simple one, when you send emails a certain amount will get replied to, this is the average amount, it makes the emails look more human.
The warm up period should ALWAYS be 2 weeks.
Meaning:
If you buy, connect, and start your warm up for your email accounts on August 1st, the soonest you can begin sending in August 15th
Lastly, DO NOT TURN OFF WARMUP ONCE YOU BEGIN SENDING!
Warmup should stay on forever and will send in congruence to your cold emails (Don't worry it won't affect you volume)
2. Getting The Right Email Accounts
In 2023/2024 EVERY email provider cracked down heavily on cold email (Gmail, Outlook, Zoho).
You have to be light on your feet, always able to adapt if you want to succeed in cold email.
The three major public infrastructure providers:
1
Google
Google recently started cracking down on cold email, and is starting to make it harder and more expensive to use GSuite.
2
Microsoft
Microsoft is really the only recent option left. In the the future, they will inevitably also impose stricter restrictions, and will require some sort of new circumvention.
3
Zoho
Zoho is just a flat out NO. Do not use it. You will get banned SO quickly. They don't like cold email
The other option β€”> Private Infrastructure
These are very similar to public infrastructure and have servers that essentially do what Outlook and Gmail servers do. However, they can be more unreliable at times depending on which option you choose.

1. Superwave β€” This is by FAR the most reliable private infrastructure option but its also the most expensive (Around $15k/year USD)
2. Mailscale β€” This is probably the cheapest option but also the least reliable ($220 for 200 accounts/month | many have had deliverability issues)
3. Making Sure Your Domains Are Setup The Right Way.
When you start cold email, you're going to need domains for your email accounts.
NEVER USE YOUR CORE COMPANY DOMAIN
Always buy secondary sending domains which all look similar to your core domain
For example:
Lets say your company's name is β€” cold.com
In order to send 2,000 emails per day you need 50 email accounts that will come from 25 domains.
These domains need to be variations of email.com, likeπŸ‘‡
  1. gocold.com
  1. wearecold.com
  1. thecold.com
  1. heycold.com
  1. coldhq.com
  1. hicold.com
  1. hqcold.com
  1. & so on.
Key Things To Remember:
  1. Never use number or symbols in your domain names
  1. EX) the-cold-agency.com
  1. EX) thecoldagency12.com
  1. Preferably always use .com domain endings
  1. .com and .co domains are $12 per year, they aren't expensive. However, at scale you'll eventually run out of domains you can buy, so you'll need to use .biz & .info , DO NOT BUY ANY DOMAINS WITH ANY OTHER ENDINGS.
  1. Forward all your secondary domains to your main domain
  1. Lets say you buy 25 domains. You're not going to make a website for all 25 of them. Obviously you have to have a website though. So what do we do? We forward all your secondary domains to your main domain so when a prospect pastes your domain in Google they get taken to your main domain's website.
  1. DNS Records
  1. This only applies if you are using outlook, as the other providers do this automatically.
  1. There are 3 main DNS records you need to make sure are applied:
  1. DMARC
  1. SPF
  1. DKIM
You really don't need to understand the intricacies behind why these records exist, and are important, but incase you do, below is a more easily digestible explanation.
SPF, DKIM, and DMARC are like a security team for your emails. They work together to make sure your emails are seen as trustworthy.
  • SPF tells mail servers which senders are allowed to send emails from your domain, reducing the chance of your emails being mistaken for spam.
  • DKIM adds a digital signature to your emails, assuring receivers that the emails haven’t been tampered with and are genuinely from you.
  • DMARC sets the rules for how receivers should handle your emails if they don’t pass SPF or DKIM checks, and it reports back to you about any issues.
4. Lead Verification.
Lead verification is a non-negotiable when it comes to cold email. Without it, you're asking for deliverability issues.
Once you scrape a lead list from whatever platform (Apollo, Lusha, Snov.io, etc), you will 100% have invalid leads.
Businesses go out of business, employees leave their positions, others replace them & this all causes a whole lot of invalid data.
Luckily for us cold emailers β€” their are tools that can help us validate our leads.
To do this, use https://millionverifier.com - $258 for 500k credits.
This is what is known as an SMTP checker, you don't need to understand it to run cold emails, but to put it simply, it will send a request to a mailserver and ask "does this email address exist".
5. Sending Volume
Sending volume plays a huge part in your deliverability because you can't abuse it.
At the time of writing this guide, an average email account can send about 40 cold emails per day.
That number is NOT including the warm up emails that it is also doing.
Just like you warm up emails, you're supposed to scale your outreach emails.
The industry standard is that you start off with ~5 a day and then scale to say 10, 20, 30, and then to 40.
The less you send, the safer, this number DOES NOT INCLUDE WARMUP.
Currently for clients we send 30-40 emails per day and 35 warmup emails per day, with no issues.
6. Spintax
Spintax short for, spinning syntax is a popular message alternator that most of the cold email sending softwares like Smartlead & Instantly support.
Spintax looks like this:
<Hey|Howdy|Hi|Hello|What's up> {{first_name}} this is <Kareem|Daniel> from <73 Media|73 Outbound>. <We're|We are> a <Lead Generation|lead gen> <agency|company|firm> that <specializes|excels> at <cold email|outbound email|email marketing>.
If you inputted something like that into Smartlead or Instantly, your emails would look like this:
  1. What's up Bob this is Kareem from 73 Media. We're a Lead Generation firm that specializes at outbound email.
  1. Hey Julia this is Daniel from 73 Outbound. We are a lead gen company that excels at email marketing.
  1. Howdy Rob this is Kareem from 73 Media. We're a Lead Generation firm that specializes at cold email.
  1. Howdy Alice this is Kareem from 73 Outbound. We are a lead gen firm that excels at cold email.
  1. What's up Bob this is Daniel from Forge Media. We're a Lead Generation firm that excels at email marketing.
  1. Howdy Diana this is Kareem from 73 Outbound. We are a lead gen agency that excels at email marketing.
  1. Howdy Diana this is Daniel from 73 Media. We're a lead gen company that specializes at outbound email.
  1. Hello Ivan this is Daniel from 73 Outbound. We are a Lead Generation agency that specializes at cold email.
  1. Hey Julia this is Kareem from 73 Media. We are a Lead Generation firm that excels at cold email.
  1. Hi Alice this is Daniel from 73 Outbound. We are a lead gen firm that excels at cold email.
Words that stay the same:
  • This is
  • from
  • that
  • at
Everything else is constantly changing, making it a lot harder to detect you're doing cold email.
7. What NOT To Put In Your Cold Emails
There aren't many guidelines on what you SHOULD NOT put in your cold emails, but here are the most popular ones.
  1. Never include links in your first email.
Don't say something like:
Hey {{name}} this is Kareem from Forge (https://the73media.com) - how's it going?
That will KILL your deliverability
2. Refrain from uploading images or files in your first email.
Just like the links, images or files could potentially be malicious, so you cant be sharing those at scale.
3. Refrain from fancy email signatures:
Doing something like this:
Very clearly breaks the two rules above I just mentioned. Fancy email signatures have images & links in them.
8. Open Rate Tracking
For those of you who don't know, open rate tracking works by placing a 1Γ—1 pixel into your cold email that fires off when displayed in an email.
The concept is, its basically a hidden piece of code, which only runs when someone opens that email.
And obviously, when they open that email that is counted towards the open rate, which in turn makes it work.
But, just like the slide before this one, I mentioned that you should ideally keep the images & URLs out of the emails.
This is the same thing.
You should be DISABLING the open rate tracking feature of your sending tool to maximize deliverability.
Usually what we do is, we will launch a campaign with the open rate tracking enabled.
We will let it run for a day or two, to collect open rates to determine how relevant our subject line & preview text is to our audience, and then we will immediately disable it.
None of our campaigns that have been running for over a week ever have open rate tracking enabled.
To be 100% transparent β€” these vanity metrics like open rate, response rate, etc. are all just noise. The gold standard metric that you should be tracking above all is:
Call booking rate (emails sent / calls booked).
9. Email Signatures
You should be including an email signature in all of your emails.
Both Smartlead & Instantly support automatic signature appending, so as long as you have that setup you should have those softwares automatically place the email signature for you.
When you include an email signature, you not only improve your deliverability, but also make your email seem more trustworthy.
The thing is, the secret to a good email signature is to KEEP IT SIMPLE.
Don't do something crazy like the one earlier in the document.
Just do something like:
Kindest Regards,
Kareem Shaban
Founder of 73 Media
kareem@the73media.com | xxx xxx xxxx (number)
Super simple, no styles, no nothing, just regular text.
10. Sending Cold Emails That Don't Suck
You could do all of the above completely correctly, but if your cold emails are just bad, people will simply mark you as spam β€” and that will KILL your deliverability.
But people don't just go out of their way to mark emails as spam. For them to do that, your email has to just be outright horrible.
A bad email is an email that is:
  1. Irrelevant to the lead
  1. Seems deceptive and or rude
  1. Poor follow up sequences / follow up sequences that are too long
  1. Follow ups after prospect expresses disinterest.
  1. etc.
One of the worse things you can do in cold email is send emails to irrelevant prospects.
Lets say you want to work with local businesses.
And you write a script and call out restaurants.
And then you start sending that script out to all sorts of local businesses, and not just restaurants.
Imagine owning an HVAC company, and all of a sudden you're getting an email targeted at restaurant owners.
You're probably going to mark that as spam.
The other points are just as important.
The key thing to remember is although we've covered a lot of content thus far in the document, cold email is actually very simple.
All it comes down to is:
Provide a relevant offer, to the relevant person, at the relevant time with relevant proof.
If you offer a cure to cancer, to someone with cancer, and you've cured cancer thousands of times before, what do you think they're going to say?
Let me talk to my wife about it? No.
They're going to say lets get started.
