The art of cold email is an indispensable skill in B2B sales.
Cold email campaigns in B2B sales are a top channel for creating leads which is why it’s so important to address any of the reasons why an email wouldn’t make it to a prospect’s inbox. Enter cold email deliverability.
We’ve all been there. You write a beautiful, highly personalized email. You hit send and a few seconds later you get a notification that your email bounced. Heartbreaking.
The truth is, no matter how well-written or relevant your email is, a prospect will never see it if it doesn’t pass the right technical checks.
In this article, we’ll define email deliverability and cover the basics of improving your deliverability rate.

What is cold email deliverability?
In short, cold email deliverability is the likelihood your cold message arrives in someone else’s inbox.
For example, an email service provider (ESP) like Gmail or Outlook will take into account your emailing behavior.
If you’re sending hundreds of emails one day and none the next, it could put your deliverability at risk. If an ESP marks your activity as suspicious, your email could end up in the promotions or spam folder, if it arrives at all.
To help clarify this process, let’s break down the biggest factors affecting cold email deliverability: identification and reputation.
The first is identification.
To make it to their destination, emails need to pass through an authentication protocol. This process confirms it’s really you sending the emails.
To assure an ESP your email is authentic you’ll need to configure three technical records.
Sender Policy Framework (SPF)
This email authentication method determines whether an email was forged by confirming the IP address with the domain administrator from where it came.
DomainKeys Identified Email (DKIM)
This authentication method is a more advanced version of the SPF that confirms your email wasn’t messed with.
DKIM attaches a kind of digital signature from the original domain. This signature can be cross-checked for verification in the Domain Name System (DNS), a decentralized naming system that turns domain names into IP addresses.
Domain Message Authentication Reporting & Conformance (DMARC)
DMARC is an extension of the two previous authentication systems.
It’s a policy written in the DNS that determines whether your email will be checked by SPR or DKIM and what to do should an outgoing message not pass either test.
DMARC is one of the principal mechanisms for preventing email spoofing, a kind of attack where the address of an email is forged to impersonate a recognized organization or domain.
ESPs and internet service providers (ISP) keep tabs on your emailing habits. Naturally, what you send and how it’s received create a sender reputation.
This reputation is calculated and represented in a Sender Score.
What is Sender Score? Sender Score is a number that reflects the health and trustworthiness of your email. Basically, how inboxes view the emails coming from your IP address.
Based on a scale from 0-100, Sender Score analyzes your email program across a field of metrics including the number of spam complaints and whether or not you’re on any industry blacklists.
According to the official Sender Score website, you’ll want to keep your score above 70.
Best practices to improve cold email deliverability
There are many factors that can affect cold email deliverability. Let’s run through some of the best practices you can carry out to ensure your email finds its mark.
1) Warm up your new email account
If you’re using a new account, it’s good practice to warm it up before activating larger campaigns.
Immediately sending hundreds of emails with a new account is a quick way to be flagged as a spammer.
Keep a close eye on sending limits. It’s not likely you’ll hit them on Gmail, for example, nor is it recommended, but in any case where you need to launch a bigger campaign from the start, try to split the load across several email accounts.
Otherwise, cultivate some good faith in your IP address by first sending a few emails to colleagues who’ll respond.
2) Organize your prospect list
Sending emails en mass to expired, incorrect, or unresponsive email addresses is another way to get flagged as spam by an ESP.
Before you launch a campaign, double-check the validity of the addresses on your prospect list. There are a couple of ways to approach this
First, you’ll want to verify the address is valid. You can do this with one of the many paid and free email verification tools or by comparing it with other addresses at the same company.
Second, qualify your leads with a sales qualification method or process. Identifying if a prospect is the right person to contact will increase the chances of engagement and your email reaching their inbox.
Personalization is a difference-maker in cold email.
Studies claim emails with a personalized subject line are 50% more likely to be opened.
Personalizing your emails with the name of the contact or organization or even some interesting fact about the prospect that gives you a reason to contact them can do wonders for deliverability and engagement.
That little bit of research for each prospect is worth the small amount of trouble, especially once you scale your email campaigns.
It may take some work, but the result is a more natural, bespoke email that will build favor with both the ESP and prospect.
4) Avoid excessive gifs, images, or attachments
In the spirit of appearing more “human,” it’s a good idea once in a while to lighten things up with a funny gif or image.
However, too many will hurt your email deliverability. The same goes for fonts and links.
An ESP will see an email with different colored fonts and images as spam.
Attachments also put your email at risk. Offering value in the form of a whitepaper or report is standard practice. Unfortunately, those attachments can act as a trojan horse for malware and are prime targets for spam filters.
Use them sparingly when you do at all.
5) Optimize the copy and CTA
Your prospects are busy people with little time to read a long email.
In addition to avoiding spammy words like exclusive, click here, or act now, which may trigger a spam filter, keep your email copy concise, personalized, and highly relevant.
To increase responses – and goodwill with an ESP – be sure to optimize your CTA as well.
Closing an email with a straightforward question that elicits even a negative response is forward progress. An answer helps you qualify leads as well as show the ESP that you’re getting engagement out of your campaigns.
6) Use an unsubscribe link
Not every prospect is a winner.
To ensure you don’t overstay your welcome and risk them marking the email as spam, include an unsubscribe link.
It may seem counterproductive in a cold email to give a lead an easy way out, but in terms of deliverability, there’s no evidence to suggest an unsubscribe link will hurt you.
Besides, including one has the added benefit of having a contact help clean up your prospect list for you.
Make it visible enough to be seen but not command too much attention. The email signature or header are good places to leave one.
Email’s popularity is still growing so it’s no surprise it remains the go-to channel of outreach for sales professionals. It’s critical to take the necessary steps to make sure cold email deliverability is high.
You can’t engage a prospect if you can’t reach them. The extra effort in implementing these practices will go a long way to delivering a good experience for your prospects and protecting your reputation.
