Top 10 Ways to Improve Email Deliverability

Posted by

Email marketing is essential for building strong relationships with your customers. You already know that.

You’ve also probably wondered what the best techniques are to ensure the process delivers the desired results.

Killer or catchy subject lines and compelling copy get the most mentions. However, none of these are remotely relevant if your marketing emails don’t reach your audience to begin with.

If subscribers can not receive your emails, then what’s the use? So today, let’s look at some factors on how to increase email deliverability and make sure your marketing emails are landing in your subscribers’ inbox.

  • Register a subdomain

Reputation plays a vital role in email marketing, and what’s a better way to build trust than the use of a subdomain? While not for everyone, registering a subdomain exclusively for an email marketing purpose will build trust over time.

Moreover, a subdomain permits domain-specific monitoring of your IP reputation so your emails can triumph over some domain-based certification filters.

  • Employ a Double Opt-In 

Single opt-ins are the go-to these days, but the double opt-in is more efficient.

With a single opt-in, the user agrees to receive your marketing emails by ticking a checkbox. It’s easy, automatic, and a seemingly great way to build your email list.

What you might be unaware of is its high rate of spam complaints. And these could be detrimental to your sender reputation since ISPs tend to block such sending servers.

Double opt-ins help fix the issue of spam complaints as it encourages a cleaner, engaged, verified email list. The new user is required to give their consent after submitting their address. This is done by validating the address via a confirmation email.

By using a double opt-in, you’re confident that subscriptions are not just intentional but wanted.

Besides, you could employ an Email Validation Service to validate your email lists and reach a more genuine audience.

  • Perform Blacklist Checks

Email service providers employ the use of domain blacklists, such as the DNSBL and the SURBL systems, to eliminate spam emails before reaching the users.

These DNS-based blacklists defend users from IPs with an unreasonable amount of spam reports. In other words, blacklisting is for mail servers that are known to send lots of spam messages.

So if your URL or IP is on a blacklist, it doesn’t need to be you sending the spam. It could be a shared mail server affecting your email deliverability. It’s paramount to ensure that your IP isn’t on any blacklist, regardless of your level of expertise. 

This is where MxToolbox comes in. Using this or a similar web app, you could put the IP address of your mail server against 100+ realtime blacklists (otherwise called DNSBL or RBL).

If by any chance, it’s been blacklisted, the next step is to find out why (technical, policy, or evidence-based) and work towards getting ‘unblacklisted.’

  • Implement a sender policy framework

An SPF record is a cross-check of the domain name against the related IP address to determine its authenticity.

With the SPF (Sender Policy Framework) protocol, senders can specify the IP addresses that are authorized to send an email on behalf of a specific domain.

It’s a DNS record to preclude email address forgery. What does that say? This: without an SPF record in place, your emails are more likely to be rejected due to spammers falsifying headers.

Moreover, this record helps protect your customers, brand, and business from phishing, spoofing, and similar attacks. It draws you closer to your email marketing purpose.

  • Adhere to a Consistent Email Marketing Schedule

With the use of a dedicated IP address, you’re required to warm up your IP (more so if it’s been more than 30 days since you last sent an email).

Warming up gives room to send more emails as you establish a good sender reputation gradually. (More on it at the 10th point.)

Low sender score and IP rejection are two common issues faced by email marketers due to random broadcast activity and spending spikes. Hence, maintaining a schedule with consistency is a must.

  • Include Branding in Your “From” Name

Apart from reducing spam complaints, including your brand name in the “from” line takes your open rates forward.

Here’s a suggested approach: use “from [Business Name]” right after the individual name. Why a unique name, you reckon. A plethora of businesses prefers using an individual to man their email marketing to give off a more intimate touch.

  • How Much of a Reputable Sender Are You?

The sender’s reputation is a score that an Internet Service Provider assigns to the mail server of a sender. There are many factors affecting sender reputation—domain reputation, for example—but you don’t have to consider everyone.

If you’re receiving non-delivery reports, having a low sender score is a key culprit. This is because ISPs automatically reject emails that fall below a specific rating.

Therefore, have a mind to keep your sender reputation high for improving the deliverability of your emails.

  • Check Feedback Loops

Top-tier ISPs accumulate feedback into the Complaint Feedback Loops or FBLs. This lets you see the recipients who have complained about your sender email.

Getting this data point from AOL, Microsoft, and Yahoo! is easy. In the case of Gmail, only ESPs (email service providers) are permitted to access it.

Gmail users can set a Feedback Loop header that uses an ARF format different from the traditional form of most FBLs.

  • Make ISPs Trust Your IP

Since ISP filters are solely maintained to rule out spamming, showing the filters that your IP is trustworthy does the trick. Here, progression is key.

You start your campaigns by sending emails to only addresses you’re already connected with. As the messages are received and opened by engaged users, ISPs notice this and trust in your IP strengthens.

Now, expand the number of emails cautiously until you reach your peak volume.

  • Use Branding in your “from” name

To reduce spam complaints, You can use your brand’s name in your “from” line. It can also improve your open rates.

You can use this approach, Use “from [business name]” after the individual name. Increasingly some companies use an individual, to head up their email marketing to give it a more personal feel.

  • Remember to Warm-up Your IP

How do you warm-up your IP? First, by starting your campaign with low volume, and as you work up the volume, by analyzing open and click-through rates and spam complaints. These data points give an overview of how recipients react to the emails you send them.

Carry out this process before each email campaign as it establishes a positive sender reputation and assists email deliverability. To avoid sending a large number of emails (which result in bounces and opt-outs), adhere to the rules of each email provider to boost deliverability for effective email marketing campaigns.

  1. Good article thanks. How do you recommend that measure engaged users when email B2B? Where are finding that a good percentage of the opens and clicks are created by bots and spam filters. Has anyone figured out how to differentiate a real click VS a bot click? I know there are techniques tracking a hidden pixel, but I have also heard that this can be flawed. Thoughts?

    1. Hi Andrew, one of the best ways to make sure you’re getting real engagement is to clean your email list regularly. The linked guide will help.

  2. Hi,

    One way I’ve found of making sure you put out something every week (or twice a week in my case) is to enable your autoresponder to use the RSS feed from your blog, so that your subscribers have a reminder that you exist. This is also a little motivation to update your blog on a routine basis!

    Thank you for this nice little batch of tips.

    Regards,

  3. Wow! 40 million emails?! I have some serious catching up to do!
    Excellent deliverability tips anyway – everyone should follow this advice when mailing.

    Personally I prefer simple text format for emails I get but for sending I am in two minds – they are harder to track in text but I suspect they get more views and less likely to be flagged as spam, whereas html format allows for tracking and links look better, as well as of course allowing for a fancy graphical layout with more opportunities for branding and embedding CTA’s.

  4. Hi – I’m a little confused. What is the difference between an “email deliverability” company, and just an “email marketing” company? For example, MailChimp vs. SendinBlue or Campaign Monitor vs. YesMail. They all seem to offer the same stuff…is there a major difference? We’re currently using MailChimp and researching new options with a focus on our deliverability, so I’m curious to know what the difference is. Thanks!

    1. Hi Steve,

      Email Deliverability vs. Email Marketing

      The major difference between Email Deliverability and Email Marketing is that:
      Email Deliverability refers to the place where you delivered email ends up once it is accepted like the inbox, spam folder, promotions or another folder. It is also known as inbox placement.

      But email marketing covers all the aspects of online marketing sending, creating, managing as well as deliverability. The higher the email deliverability, the better is the email marketing service.

  5. Hi. I already verified my account, but I’m still only getting 5% deliverability. Most of the emails also got sent to the promotions folder. What should I do to get the right deliverability rate?

    1. Hi Oliver,
      If you want your emails to land directly in the Inbox of users, you should try Email Validation Service. This service assures email inbox delivery and reaches to a real customer. It will also help you to improve your IP reputation.

  6. All points are highly accurate and well written now i know what is email deliverability but i also have one question. How can i know that my emails are actually landing in the inbox rather than spam folders?

    1. Hi Den,

      I would suggest you validate your email lists. By Verifying your email list, you come to know the valid email address and send that to real valid ID’s. It will improve your email deliverability and improve your IP reputation.

  7. Yeah thanks! In past yeas I have faced this so many time As I was not aware by Email Validation Service. But when I come to know I always validate my Email list and then I proceed for further.

    Again thanks for this informative write-up.

    Have a great day.

  8. Hi Dob,

    It would be highly depend on what type of exercise that you are doing, most of the time people would recommend to do aerobics although the main thing to have your warm up doing the exercises of your workout.
    Dynamic stretching and moving into exercise specific warm ups ,would be the best as that primes the body for the movement that one would actually perform in the workout.
    If you would be able to do 100KG for a barbell squat, you won’t go immediately straight to 100, you will use the empty barbell for a few reps, 40KG for a few reps, 60Kg for a few, 80Kg for a few reps, before the work set.

  9. Hi Kesley,

    Here are the 5 parameters that have the biggest impact:
    1. Volume & Consistency
    2. Complaints
    3. Bounce Rate
    4. Blacklists
    5. Tracking

    1. Focus your email program on recipients who actually want to receive an email from you. This starts with growing your email list organically.

  10. Hello thanks for the information!
    Email deliverability is of most importance because to be able to drive revenue from your campaign your email must first be delivered to your subscribers’ inbox. If they aren’t getting delivered, then the email content won’t have a chance to be opened, clicked or drive any results for your business.
