How to Build an Email List That Converts in 2025

Email marketing continues to deliver the highest ROI of any digital marketing channel. For every dollar spent on email marketing, businesses see an average return of $42 — a figure that makes email indispensable for any serious marketing strategy.

Building Your Email List

A quality email list is the foundation of successful email marketing. Focus on organic list building through website sign-ups, in-store registrations, and content downloads. Purchased lists are not only ineffective — they can damage your sender reputation.

Email Deliverability

Getting your emails into the inbox — not the spam folder — requires attention to sender reputation, authentication (SPF, DKIM, DMARC), content quality, and list hygiene. Regular monitoring and optimization keep your deliverability high.

SMTP Configuration

Proper SMTP setup ensures reliable email delivery. Configure your SMTP host, port, authentication credentials, and encryption settings correctly. Connect Pulse manages SMTP configuration through an intuitive admin interface.

HTML vs Plain Text Emails

While beautifully designed HTML emails look professional, plain text emails often outperform them in engagement. Plain text feels personal and bypasses spam filters more easily. The best approach is sending both — HTML for visual appeal with a plain text fallback. For important communications like account alerts or payment receipts, plain text is almost always the better choice.
