Stop Email Marketing Failures: The Complete Guide to Recovering from Bounce Backs

Hey there! Do you dread seeing non-delivery receipts in your inbox informing you those carefully crafted email campaigns never reached subscribers? Or even worse – getting blindsided by a sudden drop in open and click rates as messages mysteriously disappear into spam folders vs landing seamlessly in inboxes?

You‘re not alone! Over 10% of marketing emails on average bounce rather than reaching the intended recipients.

But don‘t panic! I‘ve compiled everything you need to know to tackle bounce backs head on.

Whether you‘re wondering what causes these pesky email failures, want to accurately track your program‘s bounce rate, or learn ways to start improving deliverability – this comprehensive guide has you covered.

Let‘s get to it!

Why You Need to Solve Bounce Backs

Before jumping into the details, let‘s quickly recap what‘s at stake when it comes to bounce rates:

1. Lost Opportunities: Emails that bounce rather than land in subscribers‘ inboxes represent missed opportunities to connect with audiences and drive conversions. You‘re essentially setting money on fire.

2. Negative Brand Impacts: High bounce rates also signal list quality issues to ISPs. Too many can tank sender reputation, leading to further inbox placement issues down the road.

3. Wasted Resources: From creative time to sending cost, bounce backs drain resources that could provide ROI if messages seamlessly reached the intended recipients.

Simply put – bounces are bad for business. Solving them needs to be priority #1.

Average Bounce Rates by Industry

Based on the latest data from ReturnPath, no one is immune to email bounces. Rates range from 2-7% on average depending on vertical.

Let‘s explore what exactly causes emails to bounce in the first place.

Reasons Emails Bounce

Frustratingly, email failures happen for several reasons – some within your control and some aspects you simply can‘t avoid.

Hard Bounces

First, "hard" bounces occur due to permanent deliverability failures often requiring contacts to be removed from your list. For example:

Invalid Email Addresses: This happens when sending to addresses containing typos or formatting mistakes. These messages can never reach recipients.

Deactivated Addresses: Email addresses tied to deactivated accounts on domains or ESPs obviously won‘t work either.

Spam Filter Blocking: If your IP reputation falls below a certain threshold, ISPs like Gmail will permanently block all mail.

Soft Bounces

"Soft" bounces represent temporary or recoverable failures. For example:

Full Inboxes: This is common if subscribers haven‘t cleaned out older messages. Storage quotas were exceeded so new mail was blocked.

Server Downtime: Sometimes recipient servers undergo routine maintenance. Messages sent then bounce but can be re-sent later.

Over-Sized Email Content: Adding large images or attachments over recipients‘ account limits triggers failure.

The goods news with soft bounces is you often have another chance to successfully deliver the message by making some quick adjustments and re-sending.

Understanding the "why" is crucial – but also pay attention to the rate of occurrences across your program.

Measuring Your Bounce Rate

Before improving performance, you need clarity on baseline bounce rate. Here‘s the quick formula:

Bounce Rate = (Bounced Email Total / Sent Email Total) x 100

For example, if you sent 10,000 emails last month but had 500 bounces – your bounce rate is 5%.

Aim to stay under 2% long-term for optimal deliverability, with anything over 5% considered quite high.

Monitor this regularly and investigate spikes to catch issues early. With this foundation, now let‘s get into optimization best practices!

11 Steps to Reduce Bounce Rates

Ready to enjoy some very tangible deliverability gains and minimize non-deliveries? Here are my top recommended actions to implement:

#1: List Cleaning

Carefully scrub your list deleting hard bounce emails, complaint addresses, spammers, etc. Reduce contamination allowing more focus on engaged users.

#2 List Segmentation

Divide contacts by levels of engagement. Treat highly active subscribers differently than non-openers to improve relevancy.

#3: Re-Engagement Campaigns

If someone hasn‘t opened in 6+ months, they may forget they signed up. Send updated preference center links allowing list self-management.

#4: Email Authentication

Methods like SPF, DKIM etc confirm you actually sent the email, increasing trust and inbox placement.

#5: Increase Engagement

More opens, clicks and postivie actions signal relevancy to ISPs. Deliver value with each send.

#6 Optimze Content

Ensure no spam trigger words, over-the top sales language, suspicious links exist which might trigger spam filters.

#7 Right-Size Volume

Mailbox providers watch activity closely. Sudden large volume spikes can overwhelm new IPs with throttling. Slowly ramp up sends.

#8 Inbox Placement Tests

Use a service like MailTestPro to confirm your exactly delivery, spam folder or tabbed inbox rates across major ISPs.

#9 Implement Feedback Loops

Proactively find out which messages bounced and why by provider. Adjust approach accordingly.

#10 Update Diagnostic Metrics

Closely monitor key metrics like hard vs soft bounces, failure reason codes, retry potentials to guide improvements.

#11 Cultivate ISP Relationships

If possible, actively communicate with mailbox providers about content, compliance and proving clean lists.

An equally critical component is utilizing advanced verification solutions to maintain squeaky clean subscriber data of valid, engaged recipients.
