Dynamic Emails: Create Personalized Email Campaigns That Convert

‘Dynamic Emails‘ are the future of cold email marketing.

As an email marketer, you must have felt the need to send differently personalized emails to different prospects in a single campaign.

Emails that differ in content from prospect to prospect based on the different data elements in prospect information are what we at smartreach.io define as Dynamic Emails.

TL;DR

• What are Dynamic Emails? Emails that change parts of the content using conditional logic (e.g., location, role).
• Efficiency boost: One campaign can send dozens of personalized versions without manual editing.
• Syntax example: {% if location == 'Mumbai' %}…{% endif %} or {% case tech %}…{% endcase %}.
• Best for: Sales outreach, recruiting, localized marketing — wherever personalization matters.
• Why it works: Higher engagement & open rates vs. static merge-tag emails.

Why do you need dynamic emails in your email campaign?

Merge tags have introduced personalisation to marketing emails at scale.

But with the overuse of merge tags in templated emails, recipients can now see if an email sent is via an automated process or if it is sent personally.

Dynamic emails take personalization to a whole new dimension by building context in every email.

Having context built into your email body and subject line does wonders, as your prospects have no way to tell if you are using a templated email as the email you send can sound as if it is sent personally to them.

How to use dynamic emails in the email campaign?

To create dynamic emails, you will need the prospect information first in your SmartReach.io account.

You can use conditional statements like if, if else if , and case, within your email body to reach out to a large group of prospects and send different paragraphs of text based on the prospect’s data.

Let’s see the syntax and then check a few examples of how to use these in your emails:

if  — 

{% if location == ‘Hyderabad’ %} We are looking for Frontend engineers with experience in Angular Frameworks in Hyderabad. {% endif %}

if else if —

{% if location == ‘Hyderabad’ %} We are looking for Web Frontend engineers with experience in Angular Frameworks in Hyderabad. {% elseif location == ‘Mumbai’ %} We are looking for PHP developers within Mumbai. {% else %} We are looking for software engineers with experience in web technologies. Are you interested in working for a company that offers a healthy work-life balance? {%endif %}

case — 

{% case location %} {% when ‘Hyderabad’ %} Our team is looking for Web Frontend Engineers with experience in Hyderabad. {% when ‘Mumbai’ %} Our team is looking for PHP developers in Mumbai. {% else %} We are looking for software engineers with experience in web technologies. Are you interested to work for a company that offers a healthy work-life balance? {% endcase %}

Example of a dynamic cold email

Here is an example of a dynamic email in action inside SmartReach.io.

In the above example, you can observe that without knowing the “technology” on which the prospect is working, the email would have been generalized such that they are looking for engineers from different skill sets at different locations

By introducing conditional merge-tags, we can now add context i.e if the prospect has experience in one technology we are saying that we are looking for python developers, or PHP developers or any engineers with particular skill set and if you would be interested to work in these locations.
