When launching a new email domain in India — whether for sales, cold outreach, or marketing automation — it’s critical to warm it up properly. Without warm-up, ISPs like Gmail and Outlook may flag your emails as spam. In this guide, we’ll cover step-by-step instructions for warming up a new email domain in India, tools you can use, and compliance tips (including Indian spam and privacy norms).
Why Email Warm-Up Matters
- Improves Deliverability: Ensures your emails land in the inbox, not spam.
- Protects Domain Reputation: ISPs track sending behavior. A poor start damages long-term reputation.
- Supports Scale: Proper warm-up lets you move from 10 emails/day → 1,000+ emails/day without penalty.
- Regulatory Safety: With India’s anti-spam rules tightening, compliance protects both sender and recipient.
Warming Up a New Domain
Step 1 — Register & Authenticate Your Domain
- Buy your new domain from a reliable registrar (GoDaddy, Namecheap, BigRock).
- Set up DNS records: SPF, DKIM, DMARC.
- Add branded mailbox (e.g., hello@yourbrand.in).
Step 2 — Set Up a Warm-Up Tool
- Use tools like Lemwarm, Warmup Inbox, MailFlow, or Instantly.ai.
- These simulate email exchanges with real inboxes, improving sender reputation.
- Many offer Indian payment support (via Razorpay/UPI).
Step 3 — Start With Low Volume
- Send only 10–20 emails/day for the first week.
- Focus on sending to warm contacts (friends, team members).
- Encourage replies — positive engagement boosts trust.
Step 4 — Gradually Increase Sending Volume
- Week 2: 50–100/day
- Week 3: 200–300/day
- Week 4: 500+/day (only if reply rate remains healthy).
Week | Daily Emails | Strategy |
---|---|---|
1 | 10–20 | Send to known contacts |
2 | 50–100 | Mix in warm-up tool exchanges |
3 | 200–300 | Start outreach campaigns |
4 | 500+ | Scale with automation safely |
Step 5 — Monitor Deliverability
- Track open rates, bounce rates, and spam complaints.
- Use Postmaster Tools (Gmail) and MXToolbox for diagnostics.
Tips for Indian Businesses
- Always use a business domain (yourbrand.in), not Gmail/Yahoo free IDs.
- Add a professional signature with Indian contact info (CIN, GST if applicable).
- Follow India’s TRAI/DoT anti-spam regulations — avoid deceptive subject lines.
- Segment email lists to target tier-1 vs tier-2 cities differently.
