Use Email Authentication

Email authentication is your digital ID for messages. It tells inbox providers, "This email is really from us!"

Why it matters:

• Stops email fakery

• Boosts inbox chances

• Shows you're serious about security

Three key players:

1. SPF (Sender Policy Framework)

SPF is your bouncer. It lists which servers can send emails for your domain.

Setup:

• Add TXT record to DNS

• Include: "v=spf1 include:_spf.google.com ~all"

2. DKIM (DomainKeys Identified Mail)

DKIM adds a digital signature to your emails.

Setup:

• Generate key in email provider's admin console

• Add public key to DNS records

3. DMARC (Domain-based Message Authentication, Reporting & Conformance)

DMARC tells receiving servers what to do with emails that fail SPF or DKIM checks.

Setup:

• Create TXT record in DNS

• Use: "v=DMARC1; p=quarantine; rua=mailto:reports@yourdomain.com"

Quick comparison:

Heads up: Gmail and Yahoo now require these for bulk senders (5000+ emails daily).

Marcel Becker from Yahoo says:

"All of these requirements have been well documented best practices for years. A lot of senders have already implemented them. Authenticating your email traffic should be something that you're already doing if you care about the health of your email traffic as well as your infrastructure."

Set these up now. Your sender reputation will thank you.

2. Keep Your Email List Updated

Think of your email list as a garden. Let it grow wild, and you'll end up with a mess. Here's how to keep it tidy:

Prune regularly

Clean your list every 3-6 months. Remove bounced emails, inactive subscribers, and unsubscribes. Why? A clean list boosts your sender score and keeps costs down.

Double opt-in: Your secret weapon

Use double opt-in to verify email addresses, reduce spam complaints, and improve engagement rates. It's like a VIP check at the door of your email club.

Re-engage or remove

Got quiet subscribers? Try this:

1. Send a "We miss you" campaign

2. Offer something valuable

3. If no response, say goodbye

A smaller, engaged list ALWAYS beats a big, unresponsive one.

Watch for red flags

Keep an eye on these metrics:

Use tools to stay sharp

Email validation tools can catch typos at signup, verify old lists, and flag risky addresses. They're like spell-check for your email list.

The 25% rule

Your list naturally shrinks about 25% each year. People change jobs, switch emails, or lose interest. Stay ahead by continuously growing your list, updating contact info, and removing inactive subscribers.

Remember: A well-maintained email list is the foundation of successful email marketing. Keep it clean, and your campaigns will thrive.

3. Check and Reduce Bounce Rates

Bounces can wreck your email marketing efforts. Keeping your bounce rate under 2% is key for a good sender reputation.

There are two types of bounces:

• Hard bounces: Permanent failures (non-existent email addresses)

• Soft bounces: Temporary issues (full inboxes, server problems)

Both can hurt your sender score if ignored. ISPs use bounce rates to judge email senders.

Here's how to fight bounces:

1. Clean your list every 3-6 months

2. Use double opt-in

3. Segment subscribers by engagement

4. Send consistently

5. Watch your bounce rates closely

Use this quick guide:

Pro tip: Use email validation tools to catch mistakes before they hit your list.

"Watch for emails that always bounce", says Natalie Sullivan, ex-retention marketing manager at Avex Designs. "High bounce rates can hurt your reputation, so keep your list updated."

4. Create Engaging Email Content

Want your emails to actually get read? Here's how to make them irresistible:

Nail Your Subject Lines

Your subject line can make or break your email. Keep it short and punchy:

• Create urgency: "50% off ends tonight!"

• Ask questions: "Want higher open rates?"

• Use numbers: "5 ways to boost your sender score"

Personalize It

Generic emails are out. Use subscriber data to tailor your content:

• Include the recipient's name

• Mention past purchases

• Suggest products based on browsing history

Keep It Snappy

No one wants a novel in their inbox. Get to the point:

• Short paragraphs (2-3 sentences max)

• Use bullet points

• Clear call-to-action (CTA)

Mobile-Friendly Is Key

84% of 18-34 year olds use email preview panes. Make sure your emails look good on small screens:

• Single-column layout

• Big, thumb-friendly CTAs (at least 44x44 pixels)

• Test on multiple devices

A/B Test Everything

Don't guess - test. Try different:

• Subject lines

• Send times

• CTA buttons

• Images vs. no images

What works for one audience might flop for another. Keep testing and tweaking.

"Know what you want the outcome to be, and make sure they know it too." - Sam Bennett, Email Guru

5. Send Emails on a Regular Schedule

Want to boost your sender reputation? Stick to a consistent email schedule. Here's why it matters and how to do it:

Why Consistency Counts

Sending emails on a set schedule isn't just about being organized. It's crucial for:

• Building trust with subscribers

• Improving open rates

• Reducing spam complaints

If your subscribers know when to expect your emails, they're more likely to open them. Plus, a steady stream of emails helps you spot inactive subscribers.

Finding Your Perfect Rhythm

There's no one-size-fits-all answer for email frequency. But here's a quick guide:

Pro tip: Let your subscribers choose. Set up a preference center where they can pick their preferred frequency.

Best Days and Times to Send

Recent data suggests:

• Best days: Tuesday, Thursday, Friday

• Best times: 9-11 AM, 1-2 PM

But don't just take our word for it. Test different send times with your audience.

Sticking to Your Schedule

1. Use an email marketing tool with scheduling features

2. Plan your content calendar in advance

3. Set up automated workflows for consistent sends

Quality trumps quantity. Don't sacrifice content value just to hit a frequency target.

Breaking Your Schedule

If you need to deviate from your usual schedule:

1. Give subscribers a heads-up

2. Explain why

3. Let them know when you'll be back on track

The Bottom Line

A consistent email schedule is like a heartbeat for your email marketing. It keeps your sender reputation strong and your subscribers engaged. Start modest, test different options, and always prioritize valuable content over volume.

6. Get Subscribers to Interact with Emails

Want better sender reputation? Make your emails irresistible. Here's how:

Personalize Like a Pro

Ditch the generic blasts. Get personal:

• Use names in subject lines

• Tailor content to past interactions

• Segment your list

EPS Group saw engagement spike after personalizing subject lines. Their communications manager said:

"It's the personalization that really does it for us."

Make It Visual

People love eye candy:

• Add relevant images

• Include short videos

• Use clean, mobile-friendly design

46% of email opens happen on mobile. Don't forget that.

Ask for Action

Don't just inform—inspire:

• Use clear, compelling CTAs

• Try polls or quizzes

• Add social sharing buttons

Timing Is Everything

Send when your audience is ready:

Test these times with your audience.

Offer Value

Give reasons to open and click:

• Share exclusive content

• Provide helpful tips

• Run contests

Track and Improve

Use data to get better:

• Monitor open rates, clicks, and conversions

• A/B test everything

• Remove inactive subscribers

Exemplis, a manufacturing company, hit 70% open rates on weekly emails after tracking engagement.

7. Handle Unsubscribes Quickly

Breakups happen. When subscribers want out, make it quick and painless.

Why It Matters

Slow unsubscribes hurt your sender rep. Here's the scoop:

• Average unsubscribe rate: 0.17%

• Good unsubscribe rate: Under 0.5%

Higher? Time to rethink your email strategy.

Speed Is Everything

Remove unsubscribers FAST. Here's why:

Make It Simple

1. Clear unsubscribe link

2. One-click process (no login)

3. Confirmation page (not email)

Offer Choices

Let subscribers customize:

• Email frequency

• Content types

• Temporary pause

J. Crew does this well. They let users pick frequency and email categories.

Learn and Improve

Use unsubscribe data:

• Track rates

• Analyze reasons

• Adjust strategy

Make It Memorable

• Groupon uses humor

• HubSpot suggests social media follows

Follow the Rules

CAN-SPAM Act requires:

• Working unsubscribe link for 30 days

• Honor requests within 10 days

"If you don't allow for an obvious way to unsubscribe, you'll be violating CAN-SPAM." - TermsFeed

8. Use Email Feedback Loops

Email Feedback Loops (FBLs) are your direct line to subscribers' thoughts on your emails. When someone hits "Mark as Spam", FBLs let you know. This helps you remove complainers, spot issues, and boost deliverability.

Setting Up FBLs

To get started:

• Own your domain/IP

• Set up a postmaster@ or abuse@ email

• Configure DNS records

• Maintain a good sender rep

Most big ISPs offer FBLs, including Gmail, Yahoo!, and Outlook.

FBLs in Action

1. You send an email

Your newsletter goes out to your list.

2. A subscriber marks it as spam

This is where FBLs shine.

3. The ISP sends you a report

You get a notification about the complaint.

4. You take action

Remove the complainer from your list ASAP.

Real-World FBL Examples

FBL Best Practices

1. Remove complainers immediately

2. Look for trends in complaints

3. Use insights to improve content and targeting

4. Check FBL reports often

ISPs are watching. Microsoft aims for complaint rates below 0.3%. Keep yours low to stay in their good books.

The FBL Payoff

Using FBLs right can lead to lower complaint rates, better deliverability, and a stronger sender reputation. You keep your list clean, and ISPs see you're on top of things.

9. Keep an Eye on Your Sender Reputation

Your sender reputation is crucial for landing in inboxes, not spam folders. Here's how to stay on top of it:

Mix Up Your Tools

Don't just use one tool. Try these:

1. Sender Score: Free tool that rates your IP from 1-100. Aim for 80+.

2. Google Postmaster Tools: Great for Gmail-heavy senders. Shows domain rep from bad to high.

3. Talos Intelligence: Quick "Good", "Neutral", or "Poor" rating for your domain and IP.

4. Microsoft SNDS: See how Outlook.com views your sending practices.

Key Metrics to Watch

Fix It If It's Broken

Bad scores? Try these:

• Clean your list

• Sort out authentication (SPF, DKIM, DMARC)

• Tweak your sending volume and frequency

• Boost your content and targeting

Katherine Pachowicz from CampSaver saw real results:

"We were struggling with inbox placement... We worked to improve our sender reputation. By launch time, we felt confident enough to send to our full list."

Stay on Top of It

Set a monthly reminder to check. Catch issues early, keep those emails flowing to inboxes.

10. Gradually Increase Email Volume on New IPs

Got a new IP for email sending? Don't go full throttle right away. Here's how to warm it up:

1. Start small

Send 20-50 emails per day at first. This keeps you off ISPs' radar.

2. Ramp up gradually

Double your volume every few days. Here's a sample:

3. Target engaged users

Focus on active subscribers who interact with your emails.

4. Monitor closely

Watch these metrics:

• Bounce rates (under 2%)

• Spam complaints (below 0.1%)

• Open rates

• Click-through rates

See red flags? Slow down.

5. Be patient

Full IP warm-up takes 4-8 weeks. Don't rush.

Think of ISPs like banks. New IPs are like people with no credit history. You need to build trust over time.

Conclusion

Email sender reputation can make or break your email marketing. It's not just about blasting out emails. You need to send the right messages to the right people at the right time.

Here's how to boost your sender reputation:

Your sender reputation isn't set in stone. It needs constant attention.

Charlie Wijen from Philips nails it:

"We are clear there's a straight-line relationship between better inbox placement performance and Philips' program revenue. We also now have a deep understanding of what affects our deliverability and why, which has improved our engagement levels significantly."

This shows how sender reputation directly impacts your bottom line.

Keep an eye on new rules, too. Gmail and Yahoo! are tightening up authentication in February 2024. Bulk senders will need custom domains, making sender reputation even more crucial.
