Tips On How To Inbox and Avoid Junk

If you are engaged in any kind of personal or business activity that involves bulk email delivery, you need to know how to get the most out of your emails to maximize results. That means keeping your emails out of the junk folder and in the inbox. We'll look at reasons why emails go to spam, how you can spot changes and be proactive, what you can do to prevent or recover from problems, and the ways ReachMail helps its senders keep their emails in the inbox. First, though, let define spam clearly.

The Definition of Spam

Spam is not a content issue, but instead a matter of consent. Spamhaus provides a detailed explanation of this definition which can be summarized as "A message is Spam only if it is both Unsolicited and Bulk."

It is important to start with a clear understanding of how the receiving end thinks about spam emails. Ultimately the decision to accept (deliver) or deny (bounce) an email and whether that email is put in the spam folder or the inbox is entirely up to the network receiving the emails. Laws that govern email like CAN-SPAM, CASL, or even GDPR are largely irrelevant to the question of spam folder delivery. Networks filter emails to best serve and protect their customers from fraud and abuse. In so doing, mailbox providers implement far more stringent policies than anything written into law.

Technical Definition of Spam and Explicit Consent

Taken from Spamhaus :

An electronic message is "spam" if (A) the recipient's personal identity and context are irrelevant because the message is equally applicable to many other potential recipients; AND (B) the recipient has not verifiably granted deliberate, explicit, and still-revocable permission for it to be sent.

(A) defines Bulk email delivery.
(B) defines the type of consent that is required by which a spam evaluation is made.

This requirement of Explicit Consent explains why third-party email lists, whether purchased, leased, or obtained through any form or indirect consent, will often run afoul of spam folder delivery. Explicit Consent is only obtained when recipients opt-in to receive an email directly from you.

Why Do Emails Go to Spam?

Many factors are involved in any network's decision to filter email into your recipient's inbox or spam folder. Each network is slightly different from the other, but the general theme is that positive recipient engagement is central to the entire process.

Low Open and Click Rates. Low engagement with emails can signify that your offers are not resonating with recipients but can also point to issues like list fatigue/stale data. An excellent general target for open rates is 15%-20%. Below these levels, it can be inferred that some email is being sent to spam.

Your subscriber data is getting stale. Over time any email list will age. Recipients change jobs or abandon old email accounts. These are normal occurrences that can be kept up with through regular maintenance and list cleanings . Failure to implement regular email hygiene practices can lead to cases where you're sending to many abandoned email accounts and invalid addresses. These abandoned email accountsd into spam traps in the worst cases can be recycle, hence the term Recycled Bounce or Recycled Spam Trap. Once an address has been recycled into a spam trap, it won't bounce anymore but can stay in your lists for years. Some spam traps will even open emails to remain undetected.

You need to collect more sign-ups. Collecting new opt-in subscribers is critical to keeping emails in the inbox. Some recipients will lose interest over time, and setting them aside is important for maintaining an engaged audience. So too is bringing new recipients into the fold. Newly opted-in recipients are the most likely to interact with messages.

Solutions: Create a signup form to host on your website. Engage your audience with social media .
Your offer is not compelling to your subscribers. One person's spam is another person's awaited offer. Spam is relative to each recipient. The best way to ensure that your offers are timely and compelling is to segment your audience by interest or source. Make sure your customer journey is straightforward and makes sense. Designing an email that uses the same colors and logos as the website where the recipient opted in helps with brand recognition. Automating a welcome email on sign-up helps you build a rapport with new registrants on their own schedule.

Solutions: Setup a Preference Center . Use A/B Testing on your mailing content. Set up auto messages to better engage with your audience.
Your subscriber's address isn't being used anymore. Sending to third-party email lists is a quick way to the spam folder. List Cleanings are essential when sending to third-party email data, and even then, they may not be enough on their own to keep emails out of the spam folder. Old email lists collected via opt-in forms can also be subject to this problem. An abandoned email account can be recycled into spam traps and used to target senders that use a third-party list or those that never purge abandoned email accounts from their lists.

Solutions: Read individual campaign reports . Pay for a list cleaning on your data. Remove disengaged recipients with ReachMail's Engagement Scanner .
Your recipient isn't a subscriber. Spam is not a content problem but instead a matter of recipient consent. That consent can be revoked at any time. When a subscriber opts in to receive your messages, they have entrusted you with their personal information. Consent-based email marketing works well because each recipient has granted you this trust beforehand. If you never had that trust to begin with, or have abused that trust by sending irrelevant content or sending too many offers, delivery results will be negatively impacted. Sending relevant and timely offers to segments of your subscriber audience is a great way to earn and keep that trust. Treating recipients like a means to end is libel to land your messages in the spam folder.

You aren't paying attention to subscriber preferences. Subscribers generally opt-in for something in particular, like a discount for an upcoming sale only offered to subscribers. That recipient wants to know about the current special sale, so it stands to reason that they would likely enjoy hearing about future specials as they arise. However, if someone opts in to be notified of special sales, but you also send them your weekly newsletter, covering all the normally priced products, it can lead to confusion and higher unsubscribe rates. Pay attention to what your recipients asked for when they subscribed, and make sure to send them content relevant to their interests. Defining different options, like Deals + Coupons , Weekly Newsletters , and Service Updates , for your subscribers not only shows them that you care about their interests but will help ensure your emails land in the inbox every time. Preference Centers let you offer recipients those choices to your audiences and allow you recipients to opt-out from the messages they don't want while continuing to receive the messages they find relevant.

Your customer journey is broken. Part of establishing an engaging customer journey is ensuring the consistency of your messaging. Even in cases where consent has been given, a broken customer journey can lead to similar consent-based junk folder placement. If a recipient opts in to receive an email from mybrand.com but receives an email from otherbrand.com , recipients will often view the message as unsolicited despite giving consent.

Solutions: Redesign your mailing template to use responsive design . Set up auto messages to better engage with your audience.
Your sender score is low. The sender score, or reputation, you maintain when sending emails plays a vital role in the way networks filter email to the inbox or spam folder. A sender score tends to work a lot like a credit score. Often no credit makes it harder to get a loan than bad credit. In the same way, a new brand needs to establish trust. You build your credit score by making regular monthly payments consistently. You establish a great sender score by interacting with recipients in positive ways, consistently. When recipients react positively (open, click, forward, reply) to your emails, you establish trust within that network and build a strong sender score.

Solutions: Pay for a list cleaning on your data. Remove disengaged recipients with ReachMail's Engagement Scanner . Set up auto messages to better engage with your audience.
Your content is being flagged. Content evaluation plays an important role in keeping your email out of the junk folder.

How to Measure Email Delivery Success Accurately

Email delivery results will vary somewhat from industry to industry, but the following average delivery rates can be good indicators for measuring success.

Cross-Industry Averages for Engagement Metrics

Average open rate : 18.0%
Average click-through rate : 2.6%
Average click-to-open rate : 14.1%
Average unsubscribe rate : 0.1%

open rate - the measure of how many recipients opened. (Opened / Sent )
click-through-rate - the measure of how many recipients clicks. (Clicked / Sent )
click-to-open-rate - the measure of how many openers also clicked. (Clicked / Opened )
unsubscribe rate - the measure of how many recipients unsubscribed from this email. (Unsubscribed / Sent )

Note these tend to fall under the long-held general guidelines that have remained consistent for many years: Open rates above 15% and Opt-Out/Spam rates below 0.1%.

Focusing on the Open Rate

Focusing on the open rate helps you match your email delivery to the best practices and guidelines listed at each network. Networks want you to send to recipients that are interested in the emails. They want their users to enjoy checking their email, not get annoyed digging through the spam. Users that get too much spam tend to abandon their email accounts too. Be careful where you source your email lists and how long you keep recipients around that never open. If you keep addresses around forever, you might be at risk for recycled spam traps and other list fatigue problems.

The more email you send to disinterested recipients, the more likely it is that they'll interact in negative ways, like reporting your messages as spam, deleting them, or even reporting them as abuse listing providers. Check out Google's guidelines for sending to gmail.com .

Networks like Google will penalize senders for continuing to send straight to the spam folder as well. The lower your open rates, the worse things can get if you don't take action quickly. List Cleanings and regular use of the Engagement Scanner tool we offer and quickly work on these problems.

How to use Bounces as a Call to Action

You can also use bounce rates to understand better why email is being sent to spam. Hard Bounces are invalid emails, but Soft Bounces can vary widely in reason. As is the case with filtering email into the spam folder, each network will issue soft bounces somewhat differently. Still, generally speaking, the following guideline can offer useful benchmarks across all traffic.

Hard Bounce Threshold

1% - Hard Bounce rates, or percentage of invalid email addresses in your lists, should be kept below 1% and as close to 0% as possible. Tracking changes in your hard bounce rate can help you prevent aging email data from becoming a big problem. If your hard bounce starts to climb from its current levels, use it as a call to action to investigate further.

Soft Bounce Thresholds

5% - Some amount of soft bounces may be unavoidable and not all soft bounces indicate a problem. Soft Bounce rates below 5% indicate that no networks are not identifying your traffic as problematic.
10% - A 10% or higher soft bounce may indicate that some networks are flagging your traffic as problematic. Take stems to increase targeted segmentation, improve data hygiene, etc.
15% - At least one network is identifying problems with your traffic, or many networks are starting to flag messages. Adjustments you be made imminently to avoid further escalation.
30% - Above 30% and some networks may be placing all or the majority of the messages they accept in spam and rejecting the rest.

Soft Bounce thresholds can be used as a call to action when viewed in the right context. Open rates are important but they do not paint a complete picture by themselves. Delivery blocks are generally levied by a network in response to abusive/unwanted email. Networks often throttle inbound emails, delivering some to recipients to gauge response rates and interest. If enough of these recipients respond by clicking the spam button or interact in other negative ways, the messages may be placed in the spam folder or rejected (Soft Bounced) in order to protect their users from spam. As such, removing soft bounces provides no remedy to the problem at hand, and often leads to the loss of valuable and potentially interested recipients in the process.

Using the Compare Campaigns Reports feature is a great way to see these open, click, bounce, and unsubscribe rates as they change over time too. Spotting an increase in soft bounces can be the first step towards knowing where and when to take action.

Target Email Delivery Metrics

The following targets should be understood as industry averages and may differ slightly from sector to sector. Especially for open rates, senders are encouraged to aim for open rates above 25%-35% as often as possible. Senders regularly attain 50+% open rates on targeted offers. When meeting or exceeding these metrics below, it can generally be inferred that your messages are arriving in the inbox without issue.

Open Rate 15% - 20% or higher
Soft Bounce Rate below 5%
Hard Bounce Rate below 1%
Spam Complaint Rate below 0.1%

Parting with Old, Disengaged Email Data is Necessary

It can seem unpleasant to hear that parts of your audience are no longer interested but we like to think of it a bit differently: You're busting your butt to provide a great service! Some people clearly recognize that too! Those are the openers and clickers. Part of growing your audience is taking strides to retain the existing customers of all interest levels, but what's wrong with giving preference to those that are most interested? Don't be afraid to set aside customers that stop opening and clicking for a period before trying to re-engage them.

Recognizing that recipients are individuals with their own preferences and tastes that can change over time helps you interact with your audience on their terms. The goal of the re-engagement messages should be to drive an interaction like a reply, link click, etc. Sending to recent openers will improve inbox placement. Sending the non-revenue, engagement driving offer after a few weeks of improving inbox rates helps you re-engage more recipients.

At some point, after reasonable attempts have been made to re-engage a recipient it is imperative to remove old email data permanently from your email lists. Failure to remove old email data in a timely manner can result in the collection of recycled spam traps and other old data markers that networks use to identify and block spam. As a general rule, if an address has been inactive for more than a year, it may be a potential threat to delivery results and reaching the inbox.

The best delivery results are achieved by marketing to recipients on their own terms and minimizing the efforts wasted marketing to those that have already lost interest. Prioritizing offers to the most interested and removing the old addresses that never respond can be facilitated in many ways like Tags, Preference Centers, Auto Messages, and Automated Follow Up emails.

How Networks Fight Spam

Networks use many tools and subversive tactics to identify, filter, and block spam email. One of the biggest risks of sending to third-party email lists is that some spam-fighting networks will seed their spam traps into lists that data brokers sell. Open sign-up forms are targeted by spambots to check for COI (confirmed opt-in) consent as well. Some spam traps are placed on websites but hidden so that people that scrape sites for addresses will collect them in their lists. These kinds of spam traps are referred to as Pristine Traps .
Networks recycle abandoned email accounts too. These are called Recycled Traps and can occur when senders fail to remove non-responders in a timely manner. Recipients that opted in a long time ago, but have since abandoned their email addresses may be recycled into spam traps and used to identify spam.

You can collect both Investigative Traps even if you never buy an email list. Running a COI sign-up form , and using ReachMail's SignUp Shield services help protect you from traps before you send. Even if you don't use ReachMail's sending services or sign-up forms, you can still integrate our List Cleaning services via our Zapier integration .

Networks also use metrics like Hard Bounces above 1%, or Spam Complaints above 0.1% to place the email in the spam folder. Content evaluation still plays an important role for many networks, though these methods are informed by machine learning networks nowadays, and no longer bear much resemblance to the simpler spam filters of the past that focused on flagging specific keywords.

How to Keep your Emails in the Inbox

Keeping your emails in the inbox requires paying attention to campaign metrics. Compare your reports and keep track of any changes in the data. If soft or hard bounces are going up or open ratings are going down, take this as a sign to readjust. Remove those who are not opening or clicking and ensure that the offers you're sending are being received positively. If you're receiving spam reports on your campaigns or a high number of opt-outs, it may be a sign that the content or permission of your list data is the issue. Keep close attention to opens and clicks to track what interests your audience.
