Plain Text vs. HTML Emails: When to Use Each

Getting Started

The first step is understanding where you stand today. Run a baseline audit of your current performance, identify your top three opportunities, and build a plan to capture them. The best plans are simple, specific, and time-bound — avoid 50-page strategy documents that nobody reads.

Building Momentum

Start with quick wins to build internal confidence and stakeholder buy-in. Look for high-impact, low-effort improvements: fixing broken pages, improving your top landing pages, or optimizing your best-performing ad campaigns. Early wins create the momentum needed for bigger initiatives.

Scaling What Works

Once you find what works, systematize it. Create templates, document processes, and build playbooks that let your team replicate success. The goal is to make good marketing repeatable, not dependent on any single person or flash of inspiration.

Sustaining Growth

Long-term growth requires consistent investment in both proven channels and experimentation. Allocate 70% of your budget to what works, 20% to scaling adjacent opportunities, and 10% to testing completely new approaches. This balance sustains growth while keeping you ahead of market shifts.

Deliverability and Performance

Even the best email content is worthless if it doesn't reach the inbox. Monitor your sender reputation, authenticate your domain with SPF, DKIM, and DMARC records, and avoid spam trigger words in your subject lines. Test emails across different clients and devices before sending. Track key metrics including open rates, click rates, unsubscribe rates, and conversion rates. Benchmark your performance against industry averages and continuously optimize based on what the data tells you.

Building a High-Quality Email List

Your email list is one of your most valuable marketing assets. Focus on attracting subscribers who genuinely want to hear from you by offering compelling lead magnets like templates, checklists, calculators, or exclusive research. Use double opt-in to ensure list quality and reduce spam complaints. Regularly clean your list by removing inactive subscribers who haven't engaged in six months or more. Segment your list based on behavior, preferences, and purchase history to deliver more relevant content.
