Deliverability Best Practices for Indian Brands in 2026

What changed

According to Vedam Vision, the Indian email landscape has seen a notable rise in baseline deliverability rates to 92.5%, bolstered by modernized infrastructure. However, this technical improvement has created a false sense of security for many local brands.

Vedam Vision reports that mailbox providers are now applying more rigorous, privacy-centric filtering that penalizes brands relying on legacy list-building tactics. The focus has shifted from simple delivery to active, permission-based engagement, forcing a 30-day turnaround for brands to audit and rectify their sender reputation.

Why it matters for email marketers

For practitioners, this means the 'spray and pray' era is officially dead. If your deliverability strategy is still just SPF, DKIM, and DMARC, you are already behind. The real-world impact is that your 'delivered' metrics are increasingly decoupled from 'inbox' metrics; you might see high delivery rates while your actual revenue-driving emails are being silently routed to the promotions or spam tabs.

This shift forces a hard look at list health and automation budgets. If you aren't aggressively sunsetting inactive subscribers, you are actively poisoning your domain reputation. Marketers must pivot from volume-based KPIs to engagement-weighted reporting, or risk seeing their ROI evaporate as mailbox providers prioritize user-trust signals over technical compliance.

What to do about it

1. 1Audit your last 30 days of engagement data and immediately sunset any subscriber who hasn't opened an email in six months.
2. 2Implement a one-click unsubscribe header to reduce spam complaints, which are now the primary driver of domain blacklisting.
3. 3Run a 30-day re-engagement campaign specifically for your 'at-risk' segment before purging them from your primary sending list.
4. 4Review your Google Postmaster Tools data to identify specific spikes in spam complaints that correlate with recent campaign launches.
