Ready to optimize your email marketing strategy and drive better results? Asking industry experts the right questions is the most direct route to breakthrough performance. I’m here to walk you through a list of questions you can use when hiring a new email marketing strategist, or if you want to take more control of your own email marketing efforts.
1. What’s the Most Costly Mistake in Email Marketing?
The bottom line: The biggest (and most expensive) error is failing to use and maintain your list actively. Ignoring email marketing wastes existing assets, and sending irrelevant, untested, or non-personalized content can tank deliverability and ROI.
- Don’t let your list go dormant—engage regularly with useful, targeted content.
- Comply with regulations (CAN-SPAM), never buy lists, and always use clear unsubscribe options.
- Test emails on all major devices and email clients to ensure a seamless experience.
- Personalize campaigns using data segmentation for higher engagement and conversion rates.
- Scrubbing your list and re-engaging inactive subscribers is a must.
2. What Drives Email Deliverability?
Actionable takeaway: High deliverability starts with engaged subscribers and reputable sending practices.
- Use a trusted email service provider with a strong sender reputation.
- Maintain a clean, up-to-date list—remove bounces and inactive contacts regularly.
- Segment your audience for relevant content; focus on maximizing open rates and reducing spam complaints.
- Be consistent with “from” names and email addresses.
- Always get permission; never send unsolicited emails.

3. Images vs. No Images: What’s Best for Engagement?
Expert consensus: Use images strategically to boost engagement, but never at the expense of accessibility or clarity.
- Images can set the mood and support your message—just don’t rely on them for essential CTAs.
- Optimize for mobile: include alt text, compress images, and preview emails with images disabled.
- Test plain text versus image-rich campaigns—sometimes simple wins.
- Balance visual elements with concise, actionable copy.
4. Double Opt-In: Worth the Effort?
Direct answer: Double opt-in (or confirmed opt-in) is the gold standard for building a clean, engaged list—despite the extra step for subscribers.
- Reduces risk of spam complaints and ensures higher long-term engagement.
- Creates a robust record of consent, protecting you from compliance issues.
- Pair double opt-in with a value-packed welcome email for best results.
- For special cases, consider social opt-in or one-click registration, but monitor list quality closely.
5. How Can You Grow Your Email List (the Right Way)?
Practical steps: Start by leveraging your existing customer base, then expand with integrated content and smart automation.
- Promote signups across every channel—website, social media, events, email signatures, and at point-of-sale.
- Offer valuable incentives (like exclusive content or discounts) to encourage subscriptions.
- Integrate with your CRM and e-commerce tools to automate list building.
- Make signup forms frictionless and visible throughout your site.
- Encourage viral sharing with “forward to a friend” and social buttons inside your campaigns.
6. Email List Hygiene: Why Does It Matter?
Key insight: Regular list cleaning (removing inactive and invalid emails) is essential for strong deliverability and campaign performance.
- Identify and remove subscribers who haven’t engaged in 6+ months.
- Use re-engagement campaigns before purging to try and win back lapsed contacts.
- Eliminate spam traps and hard bounces to improve your sender reputation.
7. Mastering A/B Testing for Email Campaigns
Action point: A/B testing (split testing) is your best friend for optimizing open rates, conversions, and overall subscriber engagement.
- Test subject lines, sender names, content layouts, CTAs, and send times.
- Start with one variable at a time to isolate what’s driving results.
- Monitor key metrics and iterate—never stop testing.
