Most advice on email campaigns is written for American or European audiences. India has its own rhythms: one time zone, a festival calendar that shifts every year, dozens of languages and a heavily mobile audience. These nine tips are built around those realities.
1. Plan around the Indian calendar, not the Western one
Black Friday has a following among online shoppers, but India’s biggest spending period runs from Navratri through Dussehra to Diwali. Because these festivals follow the lunar calendar, the dates move each year (Diwali is on 8 November in 2026 and 29 October in 2027), so build your campaign calendar each year rather than copying last year’s. Add Republic Day (26 January), Holi, Independence Day (15 August) and Raksha Bandhan, plus regional festivals for relevant segments.
2. Start festive campaigns early
Inboxes get crowded in the final week before Diwali. A teaser two to three weeks ahead, an early-access offer for loyal customers, then the main sale and a last-chance reminder spreads your message across the season instead of competing on the busiest day.
3. Send at the right time in IST
With a single time zone (IST, UTC+5:30) and no daylight saving, you can target one local time nationwide. Test a morning send against an evening one, since many people check personal email on their phones after work. Our FAQ on the best time to send a newsletter explains how to run the test. If you also sell abroad, create a separate segment for overseas customers and schedule for their time zone.
4. Write in your customer’s language
If you have captured a language preference, use it. A Hindi subject line for a Hindi-speaking segment, or a Tamil version for customers in Tamil Nadu, signals that you understand your audience. Keep each version native rather than machine-translated, and make sure the landing page matches. Our article on multilingual email marketing covers the details.
5. Make the subject line do the work
On a phone, you have only a few words before the subject is cut off. Put the benefit first (“Free delivery ends tonight” rather than “Our newsletter for October”) and use the preheader to add context. See how to write the ideal subject line.
6. Design light
Many subscribers read on mid-range Android phones and mobile data. Use a responsive template, compress your images, and always include live text so the message makes sense even if images do not load. One clear, thumb-sized button works better than five competing links.
7. Personalise beyond the first name
Use personalisation for things that change the offer: the customer’s city for delivery promises, their last category viewed, or their COD versus prepaid history. Segment with list segmentation so each group receives something relevant.
8. Protect your sender reputation
Authenticate your domain with SPF, DKIM and DMARC, include a visible one-click unsubscribe, and never send to bought lists. Beyond deliverability, the Digital Personal Data Protection Act 2023 requires valid consent for marketing; read how to get permission before your next import.
9. Measure by segment
Open rates are less reliable than they were because some mail apps pre-load images, so give more weight to clicks, conversions and unsubscribes. Mailpro’s campaign statistics let you compare segments side by side: language versions, city tiers, or festival versus non-festival sends.
Bonus: follow up by SMS where it helps
For a sale ending tonight, a short SMS to non-openers can recover sales email alone would miss. Remember that Indian promotional SMS requires DLT-registered headers and templates; see SMS marketing in India.
