Exploring the Benefits of Bounce Management

Kristen Wyatt on October 11, 2023

Email is an essential part of our lives, both business and personal. It’s a fast, convenient way to share information and conduct business. However, anyone who regularly sends emails (for marketing purposes or everyday correspondence) is likely to encounter email bounces at some point. In this blog, we will dive into all things email bounce-related: what they are, why they happen, how to manage, and ultimately prevent them.

What Are Email Bounces?

Email bounces occur when an email that you’ve sent can’t be delivered to the recipient’s inbox and is returned to the sender’s email server. This can happen for several reasons. But generally, reasons fall into two main categories: soft bounces and hard bounces.

Soft bounces are temporary issues that prevent the email from being delivered. Common reasons include a full recipient’s mailbox, a temporary server issue, or email throttling. These bounces often resolve themselves and the email may be delivered later. Hard bounces are permanent issues that prevent email delivery. These typically result from invalid/non-existent email addresses or blocking issues. When hard bounces occur, your mail won’t be delivered to the recipient.

Why Do Email Bounces Happen?

Understanding the cause of an email bounce is important for effective email management.

Here are some common reasons why bounces occur:

  • Invalid or Non-Existent Email Addresses: Sending mail to an address that doesn’t exist or has been deactivated will result in a hard bounce.
  • Full Mailboxes: If a recipient’s mailbox is overloaded, new emails will not be delivered. This will result in a soft bounce.
  • Server Issues: Temporary problems with the recipient’s email server or your email server can cause soft bounces.
  • Spam Filters: Aggressive filters may block your email, preventing it from reaching the recipient’s inbox.
  • Blacklisted Senders: If your domain or sending IP address is on a blacklist due to spam complaints or suspicious activity, your emails may bounce (common spam filter examples: Proofpoint, Mimecast, Barracuda).

Managing Email Bounces

Dealing with email bounces effectively is a must to maintain a healthy marketing campaign and reliable communication.

Here are some tips for managing email bounces:

  • Regularly Clean Your Email List: Remove invalid and inactive email addresses from your mailing list on a scheduled basis to reduce the number of hard bounces received.
  • Monitor Your Sending Reputation: Keep an eye on your domain and IP reputation to avoid being blacklisted. Follow best email practices (you can find more information on best practices here) to maintain a good sender reputation.
  • Use Double Opt-In: Implement a double opt-in process for your subscribers. Doing this ensures that addresses are valid and interested in receiving your mail.
  • Segment Your Email List: Group your subscribers based on their engagement, interests, and behavior. Send targeted content to specific segments in smaller batches to reduce the likelihood of bounces.
  • Respect Unsubscribe Requests: Honor unsubscribe Requests promptly to avoid sending unwanted mail and causing frustration (this will help to lower spam complaints).

Preventing Email Bounces

It can feel like an overwhelming task to completely eliminate bounces, but you can proactively reduce your bounce totals by putting these strategies in place. First, consider validating email addresses before adding them to your mailing list. Second, keep an eye on your bounce rates and address any spikes that exceed acceptable levels. The “best practice goal” is to keep your combined (soft and hard) bounce percentage under a total of 3%. Sending content that actively engages recipients is another key step to invite recipients to open and interact with mail which lowers the risk of being marked as spam. And last, but not least – opting for a reputable ESP (Email Service Provider) can be really beneficial. Talk to your ESP representative about accessing your bounce log details to manage bounces and maintain a positive sender reputation.

Bounces can feel like an unavoidable part of email communication. But with proper management, you can minimize their impact and maintain a healthy reputation. Remember to regularly clean your email lists, monitor your sending reputation, and follow best practices to ensure your campaigns reach their intended recipients. Doing so will enhance your email communication and achieve better overall results.

How To Land Into Gmail’s Inbox

Kristen Wyatt on July 31, 2023

Landing in Gmail’s primary inbox can be pivotal for email marketers and anyone sending important emails. Gmail’s inbox sorting algorithm automatically categorizes incoming emails into different tabs: 

  • Primary: Personal emails and messages from other categories where the tab isn’t turned on.
  • Social: Notifications and updates from social platforms.
  • Promotions: Promotional mail and other offers from email marketing and similar campaigns.
  • Updates: Transactional emails such as receipts and shipping notifications.
  • Forums: Mailing lists and groups.

To increase the likelihood of your emails landing in the Primary tab, follow these best practices:

Use a recognizable “From” name: Ensure your sender name is clear and recognizable. This helps recipients know who you are and why they are receiving your mail. Avoid using spammy or misleading names.

Use sub-domains: Create subdomains for each type of mail that you send (marketing, updates, transactional mail, etc). This will keep your top domain’s reputation safe. It also allows you a more detailed view of open/click tracking.  

Authenticate your domain: Implement Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC) protocols to improve your email’s credibility and reduce the chances of being marked as spam.

Use a reputable email service provider: Use a reliable and well-known email service provider that actively manages its reputation to ensure high deliverability rates.

Send relevant and engaging content: Create valuable, personalized, and engaging content that recipients are more likely to interact with. Avoid using spammy language or excessive promotional material.

Avoid spam trigger words: Refrain from using common spam trigger words in your subject linked and email content, such as 

  • Free 
  • Discount
  • Limited time
  • Satisfaction guaranteed
  • No obligation 

Limit the use of attachments and large images: Emails with large attachments or image-heavy content might be considered suspicious and end up in the Promotions tab.

Avoid excessive use of links: Too many links inside your email can make it look spammy. Use links sparingly and make sure they point to reputable websites.

Maintain a clean email list: Regularly clean your email list to remove inactive or unengaged subscribers. Sending emails to unresponsive addresses may increase the chances of your emails being marked as spam.

Encourage recipients to move your emails: Include a call-to-action in your emails, asking recipients to move your emails to the Primary tab if they find them there. For example, ask them to drag and drop your email from the Promotions tab to the Primary tab.

Request adding your email address to contacts: Encourage subscribers to add your sending address to their contacts list. This action signals Gmail that the user considers your email as important.

Monitor and adjust your email strategy: Pay attention to your email open rates, click-through rates, and spam reports. Consider utilizing Google Postmaster Tools to gain more detailed insight into how Google views your sending domain(s). Adjust your email strategy based on the data to improve engagement and reduce spam complaints.

Remember, getting into the Primary inbox is not entirely within your control. Gmail’s algorithms are dynamic and always subject to updates. However, following these best practices should help improve your chances of landing there. Also, make sure that you comply with Gmail’s guidelines and policies to maintain a positive sender reputation.

5 Tactics to Overcome Deliverability Challenges

Kristen Wyatt on June 21, 2023

All marketers would love for their campaigns to be delivered to the inbox and opened by all of their recipients. In reality, this is not the case. There are multiple challenges that email marketers must overcome. This blog post will focus on the 5 tactics that marketers can use to overcome email deliverability challenges.

Check your HTML and Plain Text versions

Filters like to see a plain text alternative. HTML version-only emails are a red flag for spam filters. Ensure that your Plain Text version matches the HTML version. Many platforms don’t always copy the text over on new email templates. Plain and simple, some people prefer text emails.  Since a variety of email clients give their users the option to only receive the plain text version of an email, it’s important to send campaigns in a multi-part MIME format.  If your subscribers have enabled this setting and you only send an HTML version, they may not receive your mail.

Review daily campaign and deliverability reports

It is critical that all email marketers review their campaign reports inside their ESP (Email Service Provider) on a daily basis. Look for and review specific metrics that could signal an immediate deliverability issue.  That would include:

  • Hard bounces – This bounce rejection reason from the recipient mail server indicates a permanent delivery failure.  Retried delivery attempts will not be successful.  An example of a hard bounce would be a bad mailbox.
  • Soft bounces – This bounce rejection reason from the recipient mail server indicates a transient delivery failure.  Retried delivery attempts may be successful.  An example of a soft bounce would be a mailbox full.
  • Unsubscribes – The number of email recipients that have clicked the unsubscribe link at the bottom of the email.
  • Complaints – Those email recipients that have clicked the Spam button inside of their email client.

Test and review all email signup forms

Email signup forms are another critical component to email deliverability that many email marketers don’t think about. Are you making sure that these email forms work? Do they collect the appropriate data? Do these email forms comply with all of the domestic and international email compliance laws?

Test the unsubscribe link

Do you use a one-click opt-out option or a preference center? Do you even know how your unsubscribe process works? Continuous testing of the unsubscribe link is crucial for Deliverability. If the unsubscribe link is not working, many email recipients could be clicking the spam button to get off of your list. It is also a best practice to include other ways for subscribers to follow you, including social media. Some subscribers would prefer using social media to get updates from you, instead of email.

Sign up for Google Postmaster Tools

Gmail has stated that less than 0.1% of email in the average Gmail inbox is spam.  Historically, Gmail has not offered any insight into email metrics for senders.  The Gmail feedback tool was launched a few years ago, but the tool is offered in the form of aggregated spam statistics, which cannot be traced back to the email address of the recipient who marked the mail as spam.  Google states that these Postmaster Tools are for qualified high-volume senders, like email service providers, to monitor senders closely.  By visiting https://www.gmail.com/postmaster/, high-volume senders can get email specifics including data on delivery errors, spam reports, and reputation.

To get started, there is a 3-step process to get the dashboard set up.  You will need to prove that you own the domain by entering the DNS TXT Record or the DNS CNAME Record.  The TXT record should not be removed after Google verifies it.  According to Google, it will be tested periodically to make sure the domain still belongs to you.  Once it’s verified and emails are flowing, you will get access to the data that Gmail is sharing about your deliverability.
