But first, let’s understand…


Email Outreach: Then v/s Now


25 years ago, email wasn’t even a thing. Though the email was invented in the 1970s, it became popular in the late 1990s. Since then, emails have transformed communication.


The Old World


Businesses adopted a company-focused approach rather than a customer-focused approach while sending emails. It was marked by:

❌ Standard and impersonal company sales pitch with no relevance to customers' needs

❌ The same copy-pasted template sent to 1000s of people

❌ No tailoring to individual customers’ interests and personal details


While it might have worked in the 90s, with the growing amount of messaging platforms and social media distractions, this approach is failing.

How do you compete against elaborate algorithms that tailor content to each user, when you send the same standard message to everyone.


It makes people feel like an entry on a spreadsheet. As a result, this type of email marketing brings little to no results now.


The New World


Enter EMAIL PERSONALIZATION. And the way of communication transformed completely. Contemporary email marketing then became all about:


✅ Customer-focused approach with relevant value propositions

✅ Shift from mere ‘selling’ to long-term relationship building

✅ Personalized content tailored for the interests of each customer


And with personalization, Emails were back as one of the most important strategies for finding prospects and business growth.


Now, you already know how important email personalization is for lead generation and customer acquisition. But… the question is how to start!


Begin by collecting and assimilating data for personalizing your emails.


To personalize cold outreaches through emails, you need to know exactly WHO your customers are. Start by defining your target prospect persona, that’d help you segment the emails and personalize them better.

What Fields Can You Personalize in Emails?

Everything, we say!

  • Subject Lines / Titles

Titles are the most important element of any email, deciding whether your email will be opened or not. It's the first lines a prospect will read from you. You can Personalize the subject line by:

  • Asking a question

  • Their name

  • Their company’s name

  • Relevant Industry News

  • Recent Achievements (a "Congrats FirstName!" does the job 😉)

  • Recent Activity on Social Media (people interacted with, posts they’ve commented on)

TIP: Use your prospect’s name in the subject line to yield 26% higher open rates.

  • Salutations

That Dear Sir/Madam ,Greetings , To Whom it may concern can seriously hurt your email outreach campaign 😔. The goal is to be human. Personalize salutations with:

  • "Hi First Name" and "Hello First Name"

  • No salutation and use "First Name" only

  • Common interests (like: Fellow Jedi Warrior)

TIP: the closer you get to a real in person salutation the better the results.

  • Preview Text / also called "preheader"

The ultimate CTA to open your emails is the short email snippet your prospect sees. It's what appears on their as notification on mobile or desktop screens on the inbox. It affects whether to open the mail or trash it. Personalize the preview text with:

  • Reference to a Point of Contact (someone both of you know)

  • An interesting hook relevant to their company or industry (news, stocks, etc.)

  • Recent action they took or official announcement

TIP: The preheader's length should be 40-130 characters to optimize for mobile and desktop. Use your first lines wisely.

  • Sender’s Name and Address

The From name and email address is something most people overlook. Make sure your email is set up with your name so it appears on the prospect's inbox.


People want to connect with real people. Not no-reply@…, info@…, contact@… — So, avoid those email addresses unless it contains purely one-directional communication.

  • Email Body Copy

Now, when you have hooked your prospect with the title and blurb, amp it up by an interesting email copy. Customize it by including details like:

  • Name (while asking a question or leading to an action)

  • Recent activity

  • Industry news

  • Content they might be interested in that would deliver immediate value to their work

  • CTA Button Copy (with the action you want them to take)

TIP: Make it about THEM, not YOU.
