Email Marketing Best Practices - How to Send Emails That Actually Work

Email inboxes are noisier than ever. With billions of emails sent daily, it's not enough to simply hit Send and hope for the best. To get opens, clicks, and conversions, your emails must be intentional, targeted, and engaging.

This guide shares updated, action-ready best practices that help South African SMEs and nonprofits cut through the clutter and get results using BulkMail.

1. Build and Maintain a Clean Subscriber List

A successful email campaign begins with a healthy list. It's not about how many people you send to — it's about who you're sending to and how they got there. Focus on building trust and compliance from the start.

• Always collect emails through explicit opt-in (never buy lists)
• Use double opt-in to validate addresses and protect deliverability
• Regularly remove inactive subscribers to protect your sender reputation
• Add opt-in forms throughout your site — homepage, footer, blog, popups, hello bars

POPIA requires consent — so make sure every email you send has a valid subscription trail.

2. Automate With Purpose

Email automation allows you to stay consistent without doing everything manually. With the right setup, you can nurture leads, onboard subscribers, and re-engage contacts — all on autopilot.

• Set up welcome emails that send within 24 hours
• Use drip sequences to nurture leads over time
• Create segment-specific automations (e.g. donors, volunteers, customers)
• Schedule birthday, anniversary, and re-engagement campaigns

Automation keeps your email marketing consistent, scalable, and timely.

3. Keep Messages Short, Sharp, and Relevant

Attention spans are shrinking, especially in email. The quicker you get to the point, the more likely your readers are to engage. Brevity paired with clarity wins every time.

• Stick to one topic per email
• Use short paragraphs and clear subheadings
• Highlight the value to the reader in the first sentence
• Always include a strong, visible call-to-action (CTA)

Emails under 125 words tend to perform best for engagement.

4. Craft Subject Lines That Spark Interest

The subject line is your first impression — and it determines whether your email gets opened or ignored. Make it compelling, concise, and relevant.

• Use 4–6 words max
• Avoid spam triggers like "Free" or "Act Now"
• Personalise if relevant (e.g. region or role)
• Preview text should reinforce the subject

Test subject line formats:

• Benefit: "Grow Your List in 3 Steps"
• Curiosity: "You Probably Missed This Email Trick"
• Urgency: "Last Chance to Register Today"

5. Personalise Everything You Can

Generic emails get ignored. Personalised emails get read. Whether it’s using a name or segmenting by interest, adding a human touch boosts performance.

• Use first names when possible
• Reference previous actions (e.g. "Thanks for attending our webinar")
• Tailor content to list segments: interests, location, behaviour

Personalisation boosts open and click rates. BulkMail allows easy use of custom fields.

6. Be Consistent, But Not Annoying

Consistency builds trust, but too many emails can push subscribers away. Find your rhythm and respect your audience’s inbox.

• Start with 1 email per week
• Give subscribers options to change frequency
• Set expectations in the welcome email
• Monitor unsubscribes after each send

Balance is key. Too frequent = fatigue. Too rare = forgotten.

7. Optimise for Mobile First

Most emails are opened on smartphones. If your layout doesn’t work on mobile, you’ve already lost the click. Prioritise mobile-friendly formatting from the start.

• Use responsive templates
• Avoid tiny fonts (14pt+ recommended)
• Use buttons, not links, for CTAs
• Compress images for faster loading
• Include a plain text version

More than 60% of BulkMail opens happen on mobile devices.

8. Test, Measure, and Improve

The best email marketers don’t guess — they test. Track performance and adjust your campaigns for continuous improvement.

• A/B test subject lines, send times, CTAs
• Track open, click, bounce, and unsubscribe rates
• Use UTM links to track traffic in Google Analytics
• Make data-driven decisions for your next campaign

Testing turns email marketing from guesswork into strategy.

9. Stay Out of the Spam Folder

Even great content won’t help if your emails never reach the inbox. Avoiding spam filters is a blend of technical setup and smart writing.

• Authenticate your domain (SPF, DKIM)
• Avoid spammy language and ALL CAPS
• Include a working unsubscribe link
• Use a reputable sending IP (like BulkMail's)
• Don’t embed forms or attachments

Poor practices will damage your reputation and delivery rates.

10. Always Include a Clear Call to Action

Every email should drive a single, specific action. Tell your readers what to do next — and make it impossible to miss.

• Use a single, visible CTA per email
• Make it action-oriented: "Download Now", "Book a Demo", "Support Local Kids"
• Place it above the fold
• Use contrasting button colours

Every email should drive an outcome — whether it's clicks, donations, registrations, or replies.

Final Word: Email Still Works — If You Work It

Email marketing remains one of the most powerful and affordable tools to reach, convert, and retain customers. But it only works when executed strategically.

With a POPIA-compliant list, automation flows, great copy, and ongoing testing, your BulkMail campaigns can consistently drive real results for your organisation.
