SMTP technology is revolutionizing email marketing by making it easier to create automated drip campaigns that engage subscribers, nurture leads, and drive conversions. Learn how to leverage SMTP for creating high-performing email workflows that resonate with your audience and boost ROI.
Why Drip Campaigns Outperform Promotional Emails
Recent research by Omnisend shows that automated drip campaigns achieve two times better results than traditional promotional campaigns. This emphasizes the importance of delivering the right message at the right time to the right audience. Using SMTP for these campaigns ensures reliable, fast, and secure delivery of every email, maximizing the impact of your marketing efforts.
Instead of blasting subscribers with irrelevant sales pitches, email marketers can use SMTP-powered drip campaigns to:
- Re-engage lost customers.
- Upsell and cross-sell products effectively.
- Foster consistent communication with their audience.
What is a Drip Campaign?
A drip campaign is an automated series of pre-written emails sent to subscribers over a period of time. These emails are “dripped” out based on triggers and predetermined schedules, making them perfect for nurturing leads and encouraging conversions. SMTP enhances this process by ensuring that each email is delivered reliably, regardless of the volume.
Benefits of Using SMTP for Drip Campaigns:
- High Deliverability: SMTP ensures your emails land in the inbox, not the spam folder.
- Consistency: Every recipient receives emails in a timely and systematic manner.
- Scalability: Handle large email volumes with ease during peak campaigns.

How Many Emails Should Be in a Drip Campaign?
There’s no universal rule, but drip campaigns typically include 4 to 11 emails sent over several days. The optimal number depends on the campaign type:
- Welcome Campaigns: 3-5 emails over one week.
- Abandoned Cart Campaigns: 2-3 emails over three days.
- Win-Back Campaigns: 6-8 emails over three months.
Examples of Effective Drip Campaigns

- Email 1: Welcome and introduce your offerings.
