Email and WhatsApp marketing is the use of consent-based emails, newsletters and WhatsApp messages, broadcasts and automated flows to welcome new contacts, nurture leads, send reminders and bring customers back to buy again. PageOnTop is a Coimbatore agency that plans, writes, sets up and measures these campaigns, with AI for speed and people for voice and care.
Written by the PageOnTop team, Coimbatore · Updated November 2026What is email and WhatsApp marketing, and why does it bring the best return?
Email and WhatsApp marketing is messaging people who agreed to hear from you, with useful updates, offers and reminders, so you can bring them back to buy without paying for every visit.
Ads rent attention. A list you own keeps it. Email and WhatsApp reach people on screens they check every day, at a cost far below buying the same customer again.
We start with consent and clean data, then build the key messages: a welcome, a first-purchase offer, abandoned cart and browse reminders, order updates, review requests, birthday and festival offers, and win-back messages. Each is written to be short, clear and useful, with one action.
It lifts everything else. It adds repeat sales to your store, gets more from every lead of lead generation, connects with marketing automation and gives paid campaigns a stronger finish.
AI inboxes and assistants now sort your messages.
Email providers and AI assistants now summarise, sort and filter messages by usefulness and trust. Clear subject lines, honest content, permission, good sending practice and fast replies help your messages reach the inbox and be read.
Inboxes are getting smarter. Gmail and AI assistants decide what is shown, summarised or hidden. Messages that people open and reply to get seen. Spammy ones do not.
This is how we make messaging work for people and for inboxes:
- Clear permission and consentOpt-in forms, honest sign-up promises and easy opt-outs that protect your sender reputation.
- Clean, segmented listsContacts grouped by interest, location and behaviour, so every message is relevant.
- Proper sender setupSPF, DKIM and DMARC for email, and an approved, verified WhatsApp Business setup.
- Clear subject lines and contentHonest, specific subject lines and short messages with one clear action.
- Approved WhatsApp templatesTemplates that follow WhatsApp rules, used only for people who opted in.
- Fast replies and human handoverQuick answers to replies, with a person ready for questions that need care.

- You want repeat orders and reviews on autopilot

questions.
What is email and WhatsApp marketing?
It is the use of consent-based emails and WhatsApp messages, broadcasts and automated flows to welcome contacts, nurture leads, send reminders and bring customers back to buy.
Is WhatsApp marketing allowed?
Yes, when people have opted in and you use WhatsApp Business with approved templates. We set up consent and templates correctly, and avoid anything that risks your number.
Can you use my existing contact list?
Only if those contacts gave permission. We review your list, clean it and set up proper consent for new sign-ups.
How often should I send messages?
It depends on your customers. Many brands do well with one or two emails a week and WhatsApp messages only for useful updates and key offers. We test and adjust.
Which is better, email or WhatsApp?
Both work, in different ways. Email suits content and longer messages. WhatsApp suits quick updates and conversations. We combine them around each customer’s journey.
Can you automate follow-ups?
Yes. We set up welcome, abandoned cart, order update, review request and win-back flows, linked to your CRM or store through marketing automation.
Do you write the messages?
Yes. Our team writes emails and WhatsApp messages in your brand voice, in English or Tamil, and you approve them before sending.
What does email and WhatsApp marketing cost?
It depends on list size, message volume, tools and the work needed. After a free audit we give a clear quote, with tool costs shown separately.
