How to Fix Low Open Rates in Your Campaigns

Are your email campaigns getting few opens? Do you send an email and only a small fraction of your audience opens it? This article explains how to fix low open rates in your campaigns—step by step, simply, for Nigerian, Kenyan, Ghanaian, Ugandan, and South African audiences.

We’ll cover definitions, root causes, many fixes (how‑to), pros and cons, comparisons with other metrics, examples, tools, a summary table, FAQs, and more. By the end, you will know exactly what to try to raise your open rates.

Let’s begin.

Understanding Email Open Rate: Definition and Importance

1.What Is Email Open Rate?

Email open rate is the percentage of delivered emails that get opened by the recipient.

Formula:

• Delivered emails = emails that didn’t bounce or get blocked

• Open events = when a user’s email client signals that the message was opened (often via a tracking pixel)

So if you deliver 1,000 emails and 150 people open, your open rate is 15%.

.2 Why Open Rate Matters for Email Campaigns

If your emails are not being opened, no matter how great your content is, people won’t see it. Open rate is a key metric because:

• It shows if your subject line, sender name, or preheader are compelling

• It indicates how interested or trusting your audience is

• It affects deliverability: poor open rates can lead to your emails being flagged as spam

• It helps you optimize your future campaigns

.3 Related Metrics to Watch

Open rate works with other metrics. Some related metrics:

• Click‑through rate (CTR): The percentage of opened emails in which recipients click a link

• Conversion rate: Percentage of those clicks that lead to the goal (sale, download)

• Bounce rate: Percentage of emails that could not be delivered

• Unsubscribe rate: Percentage of recipients who leave your list

To fully fix low open rates, you also need to consider these metrics.

Why Your Open Rates Might Be Low: Common Causes

Before fixing low open rates, you must know the possible causes. Here are the most common issues:

.1 Poor Subject Lines / Unengaging Preheaders

Your subject line and preheader are the first things the reader sees. If they are boring, vague, or spammy, people will skip opening the email.

2.Sender Name or Email Address Not Trusted

If your sender name is random (e.g. [email protected] or “NoReply”) or not familiar, recipients may ignore or delete.

.3 List Quality Problems

• Many inactive subscribers

• Many fake or invalid email addresses

• People who joined long ago and forgot why

.4 Lack of Segmentation / Relevance

If you send the same email to all your list members regardless of interest, many will find it irrelevant and not open.

.5 Frequency Issues: Too Often or Too Rare

• Sending too often irritates people => they ignore

• Sending too rarely makes people forget about you

.6 Deliverability & Spam Filter Issues

If your domain is not authenticated, or you have a poor reputation, many emails may land in spam instead of the main inbox.

.7 Weak Preview / Preheader Text

If the preheader doesn’t support the subject, or is missing, people may not be tempted to open.

.8 Timing Mistakes

If you send emails when people are asleep, at work, or during low activity periods, they may miss or ignore.

.9 Email Design / Format Problems

Big images, heavy file sizes, broken code, or non‑mobile design can cause email clients to suppress opens or hide content.

.10 Trust and Engagement Deficit

If people don’t feel connected to your brand—if past emails have been boring or too salesy—they may stop opening.

Recognizing which of these causes affect your campaigns is the first step.

How to Fix Low Open Rates: 25 Proven Tactics

Here is a rich list of actionable steps you can take to fix low open rates. Not all will apply at once; pick the ones most relevant and test them.

---

.1 Craft Irresistible, Curiosity‑Driven Subject Lines

Your subject line must make people curious enough to click “Open.”

Tips:

• Use curiosity: “You won’t believe this result…”

• Use questions: “Are you making this mistake?”

• Use numbers: “5 ways to save ₦5,000 this week”

• Use urgency or scarcity: “Only 3 spots left”

• Use personalization: “Tosin, here’s your guide”

• Example before: “Weekly newsletter”

After tweak: “Tosin, 3 study hacks you must try today”

---

.2 Avoid Spam Triggers in Subject Lines

Certain words or patterns trigger spam filters or reduce trust. Avoid:

• ALL CAPS

• Too many exclamation marks “!!!”

• Redundant “FREE FREE”, “BUY NOW”

• Excessive emojis

• Characters like $ ** $$

Keep subject lines clean, natural, and not overly promotional.

---

3. Use a Recognizable and Trusted Sender Name / Email

People open emails from names they recognize or trust. Use:

• Your real name or a team name (e.g. “Aisha from StudyHub”)

• Brand name + real name (e.g. “StudyHub Nigeria”)

• Avoid “NoReply” or random strings

Make sure your email address is from your domain (e.g. [email protected]), not generic Gmail or Hotmail.

---

.4 Add Strong Preheader / Preview Text

The preheader is the sentence or two that appears next to or under the subject in inboxes. It complements the subject.

Examples:

• Subject: “Tunde, your plan is here”
  Preheader: “See how to boost your income this month”

• Subject: “Last chance to join”
  Preheader: “Registration closes at midnight tonight”

Always fill preheader text; don’t leave default “View in browser” phrases.

---

.5 Clean and Prune Your Email List Regularly

A smaller but engaged list is better than a large, inactive one.

Steps:

1. Identify subscribers who haven’t opened in 3–6 months

2. Send a re‑engagement email: “We miss you — would you like to keep hearing from us?”

3. If they don’t respond, remove them

4. Remove bounces, invalid emails

This improves your overall open rate and protects deliverability.

---

.6 Segment Subscribers by Interest and Behavior

Do not treat all your subscribers the same. Segment them by:

• Location or city (Lagos, Abuja, Accra, Nairobi)

• Interests or categories (tech, health, side hustle)

• Engagement level (active vs passive)

• Source (social media, blog, ad)

When you send more targeted emails, readers perceive relevance and are likelier to open.

---

.7 Personalize Subject Lines and Content

Personalization increases open probability.

• Use first name: “Maryam, your update is here”

• Use dynamic content: show different subject lines based on location

• Reference a past action: “Because you downloaded our guide”

Ensure personalization feels natural, not forced.

---

.8 Test Subject Lines (A/B Testing)

Always test variations to see what works best.

• Split your list into two small parts

• Try subject line A vs subject line B

• See which gets more opens

• Use the winner for the rest of the list

Over time, you learn what style your audience prefers.

---

.9 Optimize Send Time Based on Audience Behavior

Timing influences whether your email is noticed or buried.

• In Nigeria, early morning (6–9am) or evening (7–10pm) often works

• On weekends, mid‑morning may be good

• Use your analytics: test different send times and track performance

Don’t assume one time fits all—test for your audience.

---

.10 Limit Frequency to Avoid Fatigue

Sending too many emails can cause burnout and lower open rates.

• Stick to 1–2 emails per week for most audiences

• For very engaged segments, 3 per week may work

• For new lists, start slower

Balance consistency and respect—don’t bombard your list.

---

.11 Resend to Non‑Openers (with a Twist)

People who didn’t open the first time may open if you resend with a changed subject line.

How:

1. Wait 48–72 hours

2. Change the subject slightly (e.g. “Update inside” → “Important update inside”)

3. Possibly tweak preheader or minor text

4. Send only to those who did not open previously

This can recover some opens without annoying those who already opened.

---

.12 Ensure Mobile‑Friendly Design

Many people in Nigeria, Ghana, Kenya, Uganda, South Africa open emails on their phones.

• Use responsive design templates

• Use larger fonts, single column

• Avoid tiny links

• Keep image sizes small

• Make buttons tappable

If your email is broken or ugly on mobile, people won’t engage or even open.

---

.13 Use Double Opt‑In or Confirmed Opt‑In

When subscribers confirm their email before fully joining, you reduce fake or mistyped addresses.

This ensures a cleaner list from the start, raising average open rates.

---

.14 Warm Up New Domains and IPs

If you start sending from a new domain or IP, don’t send to your whole list at once.

• Begin with small volumes (send to 50–100)

• Gradually increase volume over days or weeks

• Monitor open and bounce rates

This “warming up” helps email providers see you as legitimate, reducing spam placement.

---

.15 Use Email Authentication (SPF, DKIM, DMARC)

Set up proper domain records so that email providers trust your messages.

• SPF (Sender Policy Framework)

• DKIM (DomainKeys Identified Mail)

• DMARC (Domain-based Message Authentication)

These records help your emails land in the inbox, not spam.

---

.16 Avoid Overuse of Images / Heavy HTML

Emails with too many images or heavy code may be slow to load or flagged.

• Use a mix of text and images

• Use alt text for images

• Avoid embedding large files

• Keep HTML clean

Better to deliver a simple, light email than a fancy design that never loads.

---

.17 Use a Single Clear Call to Action (CTA)

If people see many conflicting CTAs (links/buttons), they may be confused and not open or click.

• Focus on one main CTA (e.g. “Download your guide”)

• Make it clear in subject, preheader, and body

• Reinforce the benefit

Clarity encourages opens and clicks.

---

.18 Build Trust Over Time with Value, Not Always Sales

Your subscribers open emails when they trust you.

• Send helpful tips, not just offers

• Share stories, lessons, free content

• Occasionally promote, but mostly give value

Gradually you earn their attention.

---

.19 Use Numbers, Stats, or Guarantees in Subject Lines

Numbers catch attention: “3 tips,” “7 mistakes.”
Guarantees: “Double your savings in 30 days.”
Stats: “98% of students improved with this method.”

These help subject lines stand out in crowded inboxes.

---

.20 Use Emojis Sparingly and Strategically

A well‑placed emoji can add personality and draw attention. But overuse can look spammy or gimmicky.

• Use 1 emoji max

• Use emojis related to your message (e.g. , )

• Don’t lead with emoji always

Test with your audience to see what works.

---

.21 Use Curiosity + FOMO (Fear of Missing Out)

Make readers feel they’ll miss something if they don’t open.

Examples:

• “Last chance for free access”

• “Only few hours left”

• “You may regret missing this”

Balance FOMO with honesty—don’t trick readers.

---

.22 Leverage Social Proof / Authority in Subject Lines

People trust what others already like or experts recommend.

Examples:

• “How 1,000 students improved with this method”

• “As seen in XYZ magazine”

• “Recommended by top teachers in Kenya”

Authority can push them to open.

---

.23 Monitor and Adapt Based on Analytics

Open rate is not static. Use your email tool’s dashboard to see trends.

• Compare campaigns

• Note which subject lines got high open rates

• Track open rates by segment or time

• Drop strategies that don’t work

Constant adjustment helps improvement over time.

---

.24 Re‑Engage Dormant Subscribers with Special Campaigns

For people who haven’t opened in months:

• Send “We Miss You” campaigns

• Offer incentives (discount, free content)

• Ask for feedback: “Why don’t you open our emails?”

Some will re-engage; others you may remove.

---

.25 Encourage Whitelisting / Add to Inbox

Ask subscribers to mark your mail as “not spam” or add you to their contact list (“safe sender”).

In your welcome email, include:

“Please add us to your contacts or mark us as safe so you won’t miss our messages.”

This helps your future emails reach the main inbox.

Pros and Cons of Trying to Fix Open Rates

Every strategy has advantages and trade‑offs. When you work to fix open rates, you should know both sides.

.1 Pros of Applying These Fixes

.2 Potential Challenges / Trade‑offs

However, with careful effort and consistent measurement, the advantages usually outweigh the downsides.

---

Comparisons: Open Rate vs Click Rate vs Conversion Rate

It’s useful to compare open rate with other metrics to see what’s working or broken in your email funnel.

.1 Open Rate vs Click‑Through Rate (CTR)

• Open rate measures how many people open your email

• CTR measures how many people click links after opening

A high open rate but low CTR means people open but don’t find value. That signals you need to improve content or CTA.

.2 Open Rate vs Conversion Rate

• Conversion rate is how many people complete the desired action (buy, download) after clicking

If open rate and CTR are good but conversions are low, the problem may lie in your landing page, offer, or CTA.

.3 When to Focus More on CTR or Conversions

Once open rate reaches a healthy benchmark (say 20–30%), shift more attention to CTR and conversions. But until then, open rate must improve first—no one can click what they don’t open.

.4 Funnel View

Consider the email campaign as a funnel:

If “Opened” is weak, all stages afterward suffer. Fix open rate first. Then optimize subsequent stages.

---

Real Examples: Before & After Fixing Open Rates

Here are some illustrative, realistic examples (not real names) of how applying these steps improved open rates.

Example A: Student Blog in Nigeria

• Before: Subject lines were generic: “New Post from Us,” open rate ~11%

• Fixes: Added names in subject, used curiosity, segmented by state, cleaned list of inactive users

• After: Open rate rose to ~25%

Example B: Side Hustle Seller in Kenya

• Before: Sent daily sales emails, no segmentation, no personalization

• Fixes: Reduced frequency to 2/week, focused on helpful content, improved sender name, used A/B tests on subject lines

• After: Open rate climbed from ~13% to 28%

Example C: NGO Newsletter in Ghana

• Before: Many old subscribers, emails always long, images heavy

• Fixes: Pruned inactive list, rewrote shorter emails, mobile optimized, asked subscribers to whitelist

• After: Open rates jumped from ~10% to 22–24%

These examples show that with consistent effort, open rates can improve significantly.

Frequently Asked Questions (10+ FAQs)

Below are common questions people ask when trying to fix low open rates, especially in Nigeria, Ghana, Kenya, Uganda, and South Africa.

1. What is considered a low open rate?

Generally, open rates below 15% are low. A healthy open rate often falls between 18% to 30%, depending on niche and country.

2. Why did my open rate suddenly drop?

Possible reasons: subject line change, list decay, email domain issues, spam filters, sender reputation, or sending at a bad time.

3. Can I fix low open rates fast?

You may see improvement within a few campaigns, but substantial improvement takes consistent testing and effort over weeks or months.

4. Does frequency of sending affect open rates?

Yes. Too often can cause fatigue; too rare can make people forget. Find a balance (1–2 per week usually works).

5. Should I resend emails to people who didn’t open?

Yes. But change the subject line and wait 2–3 days. Only resend to non-openers, not everyone.

6. How do I know which subject lines work best?

Use A/B testing: send two versions to small splits, compare open rates—and use the winner for the bulk audience.

7. Will personalization always raise open rates?

Not always, but in many cases yes. Personalization tends to increase open rate if the name or detail is relevant. But overdoing or using irrelevant info can backfire.

8. Why do some of my emails go to spam?

Because domain isn’t authenticated, you used spammy words, email reputation is low, or recipient’s provider marked you as spam. Use DNS settings, avoid triggers, and maintain good list hygiene.

9. Are emojis in subject lines helpful?

Yes, if used sparingly and appropriately. One emoji can attract attention; more than that may look gimmicky or spammy.

10. Does my audience location (Nigeria, Kenya, etc.) affect open rate tactics?

Yes. Cultural context, timing, language, and local interests matter. For example, sending during power outage hours or heavy rainfall times may reduce opens. Localize subject lines and timing.

11. Can I use free email tools to fix open rates?

Yes. Free tools often come with A/B testing, segmentation, analytics — enough to start. As your list grows, you may upgrade.

12. How many days should I wait to resend to non‑openers?

2 to 3 days is typical. You want enough time for people to see your first email but not so long they forget.

13. Should I remove unsubscribers immediately?

Yes. Respect people’s decision. Don’t keep sending to unsubscribed users—doing so hurts your reputation.

14. Can low open rates hurt my deliverability over time?

Yes. If ISPs see low engagement, your future emails may land in spam more often.

15. What is the role of welcome email in open rates?

Welcome emails usually have high open rates because people expect them. Use that to set engagement tone, ask to whitelist you, and introduce value early.
