How Poor Email Marketing Can Hurt Your Brand

• Not following Gmail and Yahoo’s new sender requirements for bulk senders.

Expert Advice:

? Use email verification tools like Clearout.io to remove invalid emails.

Data: A HubSpot survey found that 69% of consumers unsubscribe from emails due to too many irrelevant messages.

Why It Happens:

• Sending too many emails without value.
• Generic or misleading subject lines.
• Poorly designed email templates with broken links or low-quality images.

Expert Advice:

? Personalize emails using recipient names and past interactions.

? Maintain consistent branding across emails (logo, colors, tone).

? Ensure all links and images work before sending.

3. High Unsubscribe & Complaint Rates

Impact: High unsubscribe rates signal to email providers that your emails are unwanted, affecting future campaigns.

Data: A study by Intuit Mailchimp shows that the average unsubscribe rate is 0.26%, but poor campaigns can exceed 1%.

Impact: Violating email laws can result in hefty fines and legal actions.

Data: The CAN-SPAM Act fines can reach up to $50,120 per violation for misleading subject lines or sending unsolicited emails.

Why It Happens:

• Sending marketing emails without consent.
• Not including a physical address in emails.
• Buying email lists instead of building organic ones.

Expert Advice:

? Obtain explicit permission before sending emails.

?If you are doing a cold outreach, make sure you approach a highly targetted list and verified list with relevant content if you don't want to get marked as SPAM!

? Always include a your details to establish trust and a one-click opt-out option.

? Follow GDPR rules by allowing users to manage their data preferences.

5. Low Engagement & Wasted Marketing Budget

Impact: Poorly targeted emails lead to low open rates, click-through rates (CTR), and ROI.

Data: The average email open rate is 21.5%, but bad email marketing can bring it below 10% (Campaign Monitor).

Why It Happens:

• Generic, non-personalized emails that don’t resonate.
• Ignoring email timing (sending at the wrong time zones).
• Failing to analyze past campaign performance.

Expert Advice:

? Use A/B testing to optimize subject lines and content.

? Send emails at the right time (Tuesdays & Thursdays perform best).

? Track performance using tools like Google Analytics and email automation platforms.
