Quick Answer
Email marketing is using permission-based email to promote products, nurture leads and keep customers buying, through one-off campaigns such as newsletters and offers, and automated flows such as welcome series, cart reminders and win-back emails. SMSGatewayHub's email marketing service gives Indian businesses unlimited campaigns, an HTML editor, fast Excel or CSV imports, personalisation, automatic unsubscribe handling and real-time reports on Pay As You Go pricing.
Which email marketing campaigns and automations should you run?
Broadcast campaigns go to a list or segment on a date you choose. Automated flows send themselves when a subscriber does something. Most growing businesses run both.
| Campaign or flow | Type | Trigger | Goal |
|---|
| Newsletter | Broadcast | Weekly or monthly schedule | Stay top of mind with content, tips and updates |
| Offer and launch campaign | Broadcast | Sale, festival or new product | Drive orders from your whole list or a segment |
| Welcome series | Automated | New sign-up or first purchase | Introduce your brand and earn the first or second order |
| Abandoned cart or browse | Automated | Items left in cart or product viewed | Recover orders while intent is fresh |
| Post-purchase follow-up | Automated | Order delivered | Usage tips, review requests and cross-sell |
| Renewal and reminder | Automated | Plan, subscription or service due date | Keep customers from lapsing |
| Win-back and re-engagement | Automated | No opens, clicks or orders for a set period | Bring customers back or clean them off the list |
| Event and webinar sequence | Automated | Registration | Confirmation, reminders and replay follow-up |

What changed for email marketers?
Mailbox providers now enforce rules for anyone sending in bulk, and the way campaigns are measured has shifted too.
Authentication is mandatory
Gmail, Yahoo and Outlook require bulk senders to authenticate with SPF and DKIM and publish a DMARC policy aligned with the From domain. Mail that fails can now be rejected outright. Domain setup on bulk email
One-click unsubscribe
Marketing emails must carry a one-click unsubscribe header and a visible link, and requests must be honoured within two days.
Spam complaints under 0.3%
Keep complaints well below 0.1% and never reach 0.3%. Sending only to people who asked for your emails, and removing inactive contacts, is the surest way to stay there.
Clicks matter more than opens
Some mail apps preload images for privacy, which inflates open rates. Judge campaigns on clicks, conversions and revenue, and use opens only as a rough trend.

| Post-purchase | After delivery: how to get the most from the product | One week later: review request | Later: a related product or refill reminder |
| Win-back | "We miss you" with what is new since the last visit | A time-limited return offer | Final email asking whether they still want to hear from you; remove if no response |

| Conversions and revenue | Orders, sign-ups or bookings each email produced | Use tagged links or unique codes and match them in your store or CRM |
| Unsubscribe rate | Whether frequency and relevance are right | Segment more and send less to people who rarely engage |

Email marketing vs bulk email: which do you need?
Email marketing is about results from your subscribers: which campaigns to send, which flows to automate and how to measure revenue. Bulk email is the sending infrastructure underneath: authenticated domains, high-volume delivery, transactional email and the API. If you mainly want newsletters, offers and automated sequences, start here; if you mainly need OTPs, invoices or statements sent from your application, start with bulk email and check bulk email pricing.
Email works best next to faster channels. Use email for rich, long-form content, then send a short reminder by bulk SMS or WhatsApp when timing matters, all from one SMSGatewayHub account. Developers can wire everything together with the Email API & SMTP section of our developer docs.
Frequently Asked Questions
What is email marketing?
Email marketing is using permission-based email to promote products, nurture leads and retain customers. It covers one-off campaigns such as newsletters and offers, and automated flows such as welcome series, cart reminders and win-back emails. SMSGatewayHub provides an email marketing service for Indian businesses with personalisation and real-time reports.
What is the difference between email marketing and bulk email?
Email marketing is the strategy and campaigns you send to subscribers to drive sales and loyalty. Bulk email is the high-volume sending service underneath, which also covers transactional email such as OTPs and invoices. SMSGatewayHub offers both from one account.
What is email marketing automation?
Automation sends emails by itself when a subscriber does something, such as signing up, abandoning a cart or going quiet for a while. You set the trigger, the delay and the content once, and every new subscriber receives the right sequence at the right time.
What do Gmail and Yahoo require from email marketers?
Bulk senders must authenticate their domain with SPF and DKIM, publish a DMARC policy aligned with the From domain, offer one-click unsubscribe and honour it within two days, and keep spam complaints below 0.3%. SMSGatewayHub provides the DNS records for your sending domain and handles unsubscribes automatically.
How many contacts can I import?
SMSGatewayHub lets you import more than 100,000 contacts in about 10 minutes from Excel files or any database export in CSV format. You can then segment them and personalise every campaign with their fields.
Which email marketing metrics should I track?
Focus on clicks, conversions and revenue per campaign, and watch bounce, unsubscribe and spam complaint rates to protect deliverability. Treat open rates as a rough trend, because some mail apps preload images and inflate them.
How much does email marketing cost with SMSGatewayHub?
SMSGatewayHub uses Pay As You Go pricing for email, so you pay for the volume you send without a long contract. Exact rates depend on volume; see https://www.smsgatewayhub.com/bulk-email-pricing or call sales on 1800 102 1822.
