Best Email Marketing Practices Followed by Top Agencies in India


Email marketing continues to be one of the most effective ways to communicate with customers, nurture leads, and drive repeat sales. Despite the rise of social media and paid ads, email remains unmatched when it comes to ROI, customer retention, and personalized communication.

So what’s the secret to making it work? The answer lies in adopting the best practices followed by every top-tier email marketing company in India. Whether you’re a growing eCommerce brand, SaaS provider, or service-based business, applying these strategies can transform your email campaigns from average to high-performing.

In this article, we break down the key email marketing tactics used by India’s leading agencies and show how DI Infotech, a trusted email marketing company in India, delivers powerful results using these exact methods.


1. Audience Segmentation for Personalization

The best agencies never send the same email to everyone. They segment audiences based on:

  • Purchase history

  • User behavior

  • Email engagement

  • Geographic location

  • Customer lifecycle stage

Why it works:
Personalized emails generate 6x more transactions. Tailored subject lines and content significantly increase open and click-through rates.

DI Infotech’s approach:
They use segmentation to send:

  • Product-specific offers

  • Reminder emails to inactive users

  • Location-based promotions

  • Behavioral re-engagement campaigns


2. Clean and Verified Email Lists

Top agencies prioritize list hygiene. This means:

  • Removing inactive subscribers

  • Verifying emails before import

  • Avoiding purchased email lists

  • Regularly cleaning bounced or unengaged users

Why it matters:
Bad email hygiene leads to low deliverability, poor sender reputation, and blacklisting.

DI Infotech ensures all email lists are permission-based and cleaned every quarter to maintain 97%+ deliverability.


3. Automation for Lifecycle Campaigns

Automation is key to scaling email marketing.

Leading agencies set up workflows for:

  • Welcome series

  • Abandoned cart reminders

  • Post-purchase follow-ups

  • Product recommendations

  • Birthday or loyalty campaigns

Benefits:

  • Save time

  • Increase efficiency

  • Improve engagement

  • Nurture leads into customers

DI Infotech uses tools like Klaviyo, Mailchimp, and Sendinblue to build high-converting automation flows that run 24/7.


4. A/B Testing for Continuous Improvement

No good email campaign is launched blindly. The best agencies use A/B testing to compare:

  • Subject lines

  • Call-to-action (CTA) buttons

  • Image vs. no image

  • Email send time

  • Layout formats (single column vs. multi)

Results:
Testing helps find what resonates with your audience, boosting open rates and conversion rates over time.

At DI Infotech, every major campaign includes 1–2 variable tests to optimize results over multiple sends.


5. Strong Subject Lines and Preheaders

The first thing people see is your subject line. Top-performing agencies craft:

  • Short, clear, benefit-driven subject lines

  • Use of personalization tokens (e.g., name, location)

  • Curiosity and urgency without clickbait

  • Preheaders that complement the subject

Example:
Subject: “Lakshit, you left this in your cart!”
Preheader: “We saved it for you—get 10% off if you complete your purchase today.”

DI Infotech trains its copywriters to write subject lines that earn clicks, not get ignored.


6. Mobile-Optimized Responsive Design

Over 60% of emails are opened on mobile devices. Leading agencies ensure:

  • Responsive email templates

  • CTA buttons are thumb-friendly

  • Images load fast

  • Text is readable without zoom

  • Short paragraphs and bullet points for scannability

DI Infotech’s designers create mobile-first templates that work across devices, browsers, and email apps.


7. Visual Hierarchy and Clean Layout

The best emails:

  • Use a clear visual hierarchy (logo → image → headline → CTA)

  • Avoid too much text or clutter

  • Use brand colors and fonts consistently

  • Include white space for readability

  • Place the CTA early and often

DI Infotech follows a clean, structured layout so readers are guided directly to the action button—be it “Shop Now,” “Book a Demo,” or “Read More.”


8. Personalization Beyond the Name

Top email marketing agencies personalize:

  • Subject lines

  • Product recommendations

  • Email body copy

  • Dynamic offers

  • Time and frequency of emails

Why it works:
Emails with personalized content see 41% higher click rates and 29% higher open rates.

DI Infotech uses behavioral and transactional data to send hyper-relevant emails at the right time.


9. Clear and Compelling CTAs

Emails should have one clear objective. Top agencies use:

  • Bold CTA buttons

  • Action-focused language (“Grab Your Offer,” “Get Started”)

  • High contrast design for visibility

  • Minimal distractions around the CTA

DI Infotech ensures all CTAs are tested for clicks, tracked via UTM parameters, and optimized across campaigns.


10. Compliance with Privacy Regulations

With GDPR, CAN-SPAM, and India's DPDP Act (2023) in effect, ethical agencies:

  • Include easy-to-find unsubscribe links

  • Avoid misleading subject lines

  • Send only to opted-in users

  • Store data securely and with consent

DI Infotech is fully compliant with global data privacy laws, ensuring your brand’s reputation and legal safety.
