Email deliverability, Do you think it is the main concern to focus on improving? If your answer is YES!, then how will you improve that?

Well, No worries! Our experts have spent 30+ days to dig out some deep facts, that will blow you!

Shall we begin!?

Let’s say, you do have a well-managed email list of your customers, and can effectively send emails to all your subscribers, but there is a need for you to ensure your emails are delivered to all your subscribers.

After sending an email campaign to your subscribers, you need to measure your deliverability rates accordingly. Email deliverability rates are the crucial element that you need to seriously consider for a successful email marketing campaign.

According to the Deliverability benchmark report (2015), only 79% of emails landed in the inboxes. That means Two out of every Ten emails never reach your recipient.

It is an exercise in futility if your email can’t reach the recipient’s inbox. Here are some points that can help you to increase email deliverability and ensure your subscribers receive your emails.

  • Register a subdomain

Does reputation play a vital role in email marketing and what better way to build trust than with the use of a subdomain? While not for everyone, registering a subdomain exclusively for an email marketing purpose builds trust over time.

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

For example, if you have an e-commerce based service and you are using both transactional emails (for order confirmation) and marketing emails (for promotion) from one domain, you can’t ensure that specific emails reach the inbox. The promotional email might have low engagement. So, the separation of IP’s according to the different functions will help you ensure email deliverability.

Register a Subdomain

  • Use a Double Opt-In 

What you might be unaware of is the high rate of spam complaints. This 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 to validate your email lists and reach a more genuine audience.

For example, if you have an online clothing store and you want to engage with your customers or visitor who has visited your products but didn’t make a purchase, you can offer them a discount if they share their email address and register on your site. You can then send them a confirmation mail; Once they click on the confirmation, they become a double-opt-in subscriber.

  • Perform Blacklist Checks

Blacklist was created to protect all users from IPs that receive spam reports. Your IP can be a blacklist if you have sent lots of spam. You have to ensure your IP is not on that list.

You can use a tool like mxtoolbox, which will check an IP address against more than 100 DNS based email blacklists. If your mail server has been blacklisted, some of the emails you send may not be conveyed. Email blacklists is a typical method for reducing spam.

  • 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 help of this protocol, senders can specify the IP addresses that are authorized to send emails on behalf of a specific domain.

A sender policy framework or SPF increases the receipt of emails by an email server. Your emails will be rejected if you don’t have an SPF in place.

By using authenticated emails, you can protect your customers, brand, and business from phishing and spoofing attacks.

For example, If you want to purchase a product or service, you will most likely search for a reputable or well-known brand. It’s the same way with the use of the SPF protocol. It gives your IP authenticity a strong boost, leaving fewer chances of rejection of your emails.

  • Stick to a Consistent Email Marketing Schedule

With the use of a dedicated IP address, you need to warm up your IP (more so if it’s been more than 30 days since you last sent an email). The reason for a lower sender score and IP rejection is random and erratic broadcast activity. Maintain a regular schedule with your emails.

Warming up gives room to send more emails as you establish a good sender reputation gradually.

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.

  • 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 — for example, domain reputation and IP reputation — but you don’t have to consider everyone.

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

Therefore, have in mind to keep your sender reputation high to improve the deliverability of your emails.

  • Check Feedback Loops

Feedback loops are useful to Email service providers to detect abuse of their services. Whenever your recipient clicks on “Mark as spam,” your ESP service considers them as “complaints.”

By using feedback loops, senders are able to listen to their subscribers and can correct the situation by removing them if there are any complaints.

For example, you have sent a mail to your subscribers and they are not interested in your service but mistakenly subscribe to your mail. What happens next? They will mark your email as spam. So you have to remove them from your subscriber list. This will help you improve your email deliverability. For more details, visit the how to implement the FBL.

  • 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 connected with. As the messages are received and opened by engaged users, ISPs note this and the trust in your IP strengthens.

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

  • Use your brand name in your signature

If your brand name is well established and you use it in your signature, it reduces spam complaints and helps you to improve your email open rates.

Increasingly, some companies or organizations use an individual to handle their email marketing to give it a more personal feel.

For example, If you prepared a draft to send us an email, as the “form” name, you can use the below:

ABC
xyz.com
your company logo

  • Remember to warm-up your IP before every email marketing campaign

When you read this, the first question that comes to mind is: “How do you warm-up your IP?” The answer is – Start your campaign with a low volume and gradually 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.

Daily maximum mails per domain

Week 1 Max 1k emails/hr per IP domain
Week 2 Max 2k emails/hr per IP domain
Week 3 Max 4k emails/hr per IP domain
Week 4 Max 8k emails/hr per IP domain
Week 5 Max 10k emails/hr per IP domain
Week 6 Max 15k emails/hr per IP domain

  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.
