What is deliverability when it comes to email?

Your email marketing deliverability refers to the delivery rate of the email campaigns you send. Specifically, it refers to the percentage of emails you send which make it to your recipients’ inboxes or spam folders, vs the percentage you send which are blocked or bounce back.

The difference between delivery and inbox placement

Further to deliverability, your inbox placement rate is also a key metric to keep a close eye on. It refers to those emails which make it specifically to the inbox alone, which is ultimately what we as Email Marketers are aiming for.

Why is having great deliverability important?

Achieving and maintaining great email deliverability rates is important because, ultimately, reaching more recipients means spreading your brand message further and engaging more of your audience with your email campaign. You spend a lot of time crafting the perfect email content, subject lines, planning your audience segments and organizing your sends. 

But if your emails are never seen by your recipients because they’re never delivered to their inboxes, then what’s the point? This very important factor within your email operation is not just a metric, it has a direct impact on your ROI from email, and therefore your overall business health. 

How to achieve great email deliverability rates

There are a number of varying factors which come together and have a combined impact on improving your overall delivery rates, to help get your email campaigns more ‘seen’. Take a read of the below points and have a look through our linked posts, for our collation of the best hints, tips, help and advice:

Solid data management and list hygiene

Possibly the biggest factor in achieving good delivery rates within email marketing is good data management, and the positive effect of this cannot be underestimated. From operating a double opt-in strategy whereby your recipients need to confirm the accuracy of the data they’ve given you, to ensuring you ’clean’ your user lists at regular points throughout the year depending upon your business needs – good clean data is at the heart of what you do. 

Learning to avoid email spam traps also comes into play with practicing good list hygiene, which is something used by ISPs (Internet Service Providers) to identify and filter-out spam emailers. They take the form of email addresses that the ISPs already know shouldn’t be receiving emails, so by sending to them you highlight yourself as a poor sender. Avoiding tempting practices like buying data lists is one way to keep you out of the line of sight of spam traps, but take a closer look at the above mentioned blog post for even more detailed advice. 

Using multiple vendors to send through

Using multiple delivery vendors can have a hugely positive effect on your email campaigns’ deliverability rates, most especially due to the level of control you have over which vendors are assigned to which sends. There are two key ways in which you can utilize multiple vendors to enhance your delivery success; routing your emails via delivery provider and routing your email sends by target audience and segment. For more detailed insights, read here.

Content is king!

Your email campaign content is what will set you apart from your competitors, and help you to stand out to your savvy consumers in their ever-crowded inboxes. Ultimately, this drives engagement. And engagement means the difference between your emails appearing of a quality nature or not to the ISPs. 

Reacting to the preferences you’ve previously collected from your subscribers is the first place to start, as this will ensure that you’re serving up relevant content that is of interest to them. After consulting the preference data you hold, personalization is absolutely key. Personalizing and tailoring dynamic content as well as segmenting your audience into smaller segments will achieve maximum content-impact. 

Furthermore, avoiding poor content factors like misleading subject lines will ensure to safeguard your delivery and help to avoid those pesky junk folders. 

Send Consistency

Send consistency refers to ensuring you’re sending your emails as per the expectation you’ve set with your recipient, at the point at which they’ve signed up. Maintaining consistency in not only the volume of emails you send and when, but also the type of content you share and who exactly you’re sending to. 

This means sending on time, every time – sending only as many emails as you’ve set their expectation to receive in your sign-up text, and keeping your campaign sends consistent and to a schedule so that they know when to expect them. Sending sporadically and off-schedule will make you appear immature to both your audience but also ISPs, who are likely to score you as spammy for lack of control over your sends. 

Sending consistently also mean the difference between consistent engagement with your audience, and falling out of sync with your subscribers. This consistent level of engagement only bodes well towards your sender reputation score and ultimately your delivery, as it works to demonstrate that your users enjoy and are satisfied with your email campaigns.

Breakup on good terms.

Nobody likes to see a relationship end. But it happens, in life and in email – the unsubscribe.

And when it comes to the end, it’s best to part on good terms as it leaves the door open. Don’t play tricks and make the unsubscribe link hard to find. Doing so risks not only ending on bad terms but hurting deliverability. If the unsubscribe is hard, you’ll get a complaint, blocked, filtered out or otherwise ignored. All bad for deliverability.

Making a customer friendly unsubscribe is mostly common sense, once you know! This scientific usability test of  six major brand emails explains the best practice.
