Email marketing has the highest ROI of any marketing channel — ₹42 return for every ₹1 spent on average. But most businesses either don't use it at all, or send random newsletters that nobody reads.
The secret is automated sequences — emails that go out automatically based on what your subscriber does. Set them up once, and they work for you 24/7.
Here are the 5 sequences every business needs, with subject line templates you can use right now.
Your welcome sequence is the most important one you'll ever write. People are most engaged right after signing up — open rates can be 4x higher than normal emails. Use this window to introduce yourself, deliver your lead magnet, and set expectations.
Recommended length: 3–5 emails over 7 days
Most people aren't ready to buy when they first sign up. A nurture sequence keeps you top of mind, builds authority, and warms leads up over time before you make an offer.
Recommended length: 4–6 emails over 2–3 weeks
Someone filled in your contact form or added to cart but didn't complete. This sequence follows up automatically and recovers a significant portion of lost leads. For e-commerce, abandoned cart emails recover on average 15% of lost sales.
Recommended length: 3 emails over 3 days
The sale isn't the end — it's the beginning. A post-purchase sequence thanks the customer, sets expectations, delivers value, and plants the seed for repeat business or referrals.
Recommended length: 3–4 emails over 2 weeks
Subscribers who haven't opened in 90+ days are hurting your deliverability. Send a re-engagement sequence to either win them back or clean them from your list. A smaller, engaged list always outperforms a large, cold one.
Recommended length: 2–3 emails over 1 week
Average return for every ₹1 spent on email marketing — the highest ROI of any marketing channel.
