Not only that but more and more email servers are working to add increased safeguards.

Never Buy an Email List

Starting out an email campaign? Build an email list on your own first. Never buy an email list and start sending out emails. These emails might be valid, but the recipients are not expecting to receive messages from you.

So, there is no way these recipients are going to open your email. Some may do, but the failure ratio can hurt your marketing very much. Plus, some can even report you as spam as they don’t know and they’re not expecting anything from you anyway. The less the open rates get, the lower your sender reputation goes.

Buying an email list and starting the marketing right away is tempestuous, but it leads you nowhere anyway. So don’t waste your resources on a bought email list. Take some time and grow an email list organically.

An organic email list may not be huge, but it can generate amazing leads compared to the large one you bought. It’s better to be there when someone is expecting, neither is it a waste of time. Email marketing works the same way.

Engaged Subscribers Management

So you already have a healthy amount of subscribers already, now what? Well, it’s your time to rise and shine with those existing subscribers and make them your regular email follower. Plus, it has the secret recipe of what we’re looking for – improved email deliverability.

If you’re sending emails to the existing recipients who love your email already, there must be a rare occasion where you face email deliverability issues. Because those people are already expecting an email from you and the deliverability is proven before.

So working with engaged subscribers can save you a lot of resources and make your email deliverability rate fly. There is nothing better than interacting with people that actually care about your interaction.

There is a catch though. If you’re interacting with your best people, you must ensure to provide the best content possible. As they’re your supreme devotee, you should treat them as so. You can even make a custom email list specially made for the most engaging subscribers and reward them for their extra affection.

Simplify the Opt-Out Process

If you’re thinking that giving subscribers the option to unsubscribe is a bad idea, you’re actually thinking wrong. Providing the option to people who are not interested s a good idea. It has a great positive impact on your email deliverability as well.

Think of it this way: you send a “not-interested” subscriber a message on regular basis. It’s already bad if the recipient doesn’t even bother to check it thinking as is irrelevant. It’s worst if the recipient ends up marking your message as spam.

Some spam reports are on the way and your email marketing strategy can go downhill in no time. If so many people report your message as spam, the inbox providers and ISPs will take notice and put a spam tag on your mail.

Don’t think it’s a foolish way to let the people unsubscribe from your email list. It’s actually very clever to let the people take the easy way out. This way you can ensure betters stats and improve email deliverability effectively.

No matter what your email is about, always add the “unsubscribe” option to the messages you send out. It’s better to have less engaged subscribers than to have a huge delivery rate with barely any interaction. Don’t force people to be in flow with your content.

In case they want to check out their email from your list, make it happen easily. This way the recipients have the easy way out and your email deliverability doesn’t get affected.

No Spamming Please

It’s rule number one for any digital form of communication, but let’s mention it once again: DO NOT SPAM.

Think of you as a subscriber who will receive these emails, would you like them? If you don’t like your email from a recipient’s perspective, don’t send it. Always avoid sounding way too robotic or obvious when writing a copy.

Plus, email servers report emails with errors as spam. Email is just another way of conversation. So don’t make it sound spammy. Stupid mistakes like writing in ALL CAPS, wrong pronoun, spelling mistakes, or even HTML errors can cost you badly. Check your email spam score before sending an email.

So whenever sending the next message, make sure to keep it neat and clean. Engage your subscribers the way you would like to be engaged as a subscriber.

Be Consistent

As an email marketer, you won’t like to confuse your subscribers by sending emails from different emails from time to time. Not only you’ll have less delivery rate, you can even get marked as spam by the recipient.

To improve your email deliverability rate, stay consistent with that one email address. It’s an easy way for the recipient to understand where the email is coming from.

Another common mistake is to change the sender’s name. Changing the sender’s name confuses your recipients. Stick with any name choose and stick with it for the next time. If you switch between your name and company name, it can be confusing on the recipient’s end.

Using the same name and address every time you send out emails is very crucial to email marketing.

Segment It

Want to build trust with your IP? Just sending satisfying emails to subscribers is not enough then. If your emails are doing well, then you increase the engagement even more through segmenting your content.

You’re not fully into it if you’re not checking out analysis and reports regularly. Don’t get hurt by any negative issues, be alert following it and act accordingly. Be consistent in checking out metrics like open and click-through rates, unsubscribes, and even spam complaints.

ISPs measure the email destination via engagement metrics, right? So you should follow them as well and keep the heads up. Negative impacts like bounce rates or complaint rates are a clear sign that you are not doing it right.

Make sure to set up a feedback look to keep the spam complaints in check. Ignoring this kind of feedback leads to more chaos. So it’s better to monitor every metric and act accordingly even if the needed step is a huge deal.

Don’t Attach PDFs

You may think attaching PDF to your mail makes things easier for customers. No matter what the occasion or issue is, always ignore sending any kind of attachments to an email campaign. If you need to send PDF anyway, try to include it within the email body. This way your mail looks less spammy and it has better deliverability.

Subscription Confirmation

While signing up using the email address, mistyping is a common occasion. So putting an extra step like email confirmation before adding an email to the list is a good idea. The invalid or wrong email ends up in the list all the time. So implementing a double opt-in tool into the signing process is always an appreciated step.

Having the option of confirming email before subscribing benefits both the marketer and customers. First of all, you get no wrong email as a marketer. Plus all the subscriber that tends to put that extra effort is more likely to result in active engagement which can be beneficial in the long run.

IP Credibility

Spam has been a never-ending problem. ISP’s filters are constantly fighting against spam. IP of incoming is a great factor regarding email deliverability. So an IP having enough credibility to ISPs plays a huge role in email deliverability.

So how can you build your IP credibility? Strategically. Start slow with your email campaign and send small batches of email to engaged subscribers. You can warm up email and when you become relevant to subscribers, your IP gets marked as a good one to ISPs.

Consistent Schedule

Maintaining consistency with your email sending schedule is easy but an effective step that can be taken to improve email deliverability. Bombarding subscribers with emails is not an ideal solution. So it’s better to stick to a consistent schedule.

Send email periodically. After maintaining a schedule a few times, your subscribers will already develop a sense of receiving your email following that schedule. So yeah, maintaining a consistent schedule help to improve email deliverability.
