Email deliverability is all about whether or not your emails actually make it to your subscribers' inboxes.
Think about it: you spend a lot of time and effort crafting the perfect email campaign, with a great subject line, compelling content, and a strong call to action. But if your emails aren't getting delivered, all of that work is going to waste.
That's why email deliverability is so important. When your emails actually make it to your subscribers, you have a much better chance of getting the engagement and conversions you're looking for. On the other hand, if your emails are getting stuck in spam filters or just not making it through at all, you're missing out on potential business.
There are a lot of factors that can impact email deliverability, from the content of your emails to the quality of your email list. But the bottom line is that if you want your email marketing efforts to be successful, you need to make sure your emails are actually reaching your audience.
Hope that helps! Let me know if you have any other questions.
By implementing email verification, businesses and individuals can increase the deliverability of their emails and reduce the risk of their messages being marked as spam. This can lead to higher engagement and better communication with their audience.
Step 1: Clean Your Email List

Having a clean email list is crucial for achieving good email deliverability. An email list is considered "clean" when it contains only valid email addresses, meaning those that are active, engaged, and have given permission to receive emails. Here are a few reasons why having a clean email list is so important:
- Avoidance of spam filters: Email service providers use complex algorithms to determine which emails are spam and which ones are not. If your email list contains a lot of invalid email addresses or addresses that have a history of marking emails as spam, your emails are more likely to end up in the spam folder, rather than the inbox. A high number of spam complaints can damage your sender reputation, and your emails may be blocked by ISPs altogether.
- Improved engagement: When you send emails to a clean email list, you're more likely to see higher engagement rates, such as open and click-through rates. This is because the people on your list have given you permission to email them and are interested in hearing from you. Higher engagement rates are a positive signal to email service providers, which can improve your sender reputation and email deliverability over time.
- Lower bounce rates: A "bounce" occurs when an email is undeliverable and is returned to the sender. High bounce rates can harm your email deliverability because they indicate to email service providers that your list may be outdated or full of invalid email addresses. By regularly cleaning your email list and removing invalid email addresses, you can keep your bounce rates low and protect your sender reputation.
- Cost savings: Many email service providers charge based on the number of subscribers on your list. By regularly removing invalid email addresses, you can reduce your list size and potentially save money on your email marketing expenses.
In summary, having a clean email list is crucial for achieving good email deliverability. It can help you avoid spam filters, improve engagement rates, lower bounce rates, and save money. Regularly cleaning your email list is an important task for any email marketer to ensure that their emails are being delivered to the right people and driving results.
Tips for identifying and removing invalid or inactive email addresses
Here are some tips for identifying and removing invalid or inactive email addresses:

These tools typically check for common formatting errors, typos, and whether the email domain is valid. Some popular email verification tools include Hunter, VoilaNorbert, and ZeroBounce.
- Look for bounce backs: When you send an email to an invalid or inactive email address, you'll often receive a bounce-back message from the email server indicating that the email couldn't be delivered. These messages will typically include an error code that can help you identify the issue with the email address.
- Monitor email engagement: If you're sending regular email campaigns, keep an eye on your engagement metrics like open rates and click-through rates. If certain email addresses aren't engaging with your content, it could be a sign that they're no longer active.

This will help keep your email deliverability high and ensure that you're only sending emails to people who are actually interested in your content.
- Be cautious of purchased email lists: If you've purchased an email list, be extra cautious about the validity of the email addresses on that list. These lists are often filled with outdated or invalid email addresses, and sending emails to them can harm your sender reputation and result in high bounce rates.
Overall, it's important to prioritize the quality of your email list over quantity. By regularly monitoring and cleaning up your list, you can ensure that your emails are reaching their intended recipients and driving engagement with your content.

Step 3: Verify Email Addresses Regularly

Verifying email addresses on a regular basis is important for maintaining email deliverability, and here's why:
First of all, email addresses can become invalid or inactive over time. People change jobs, switch email providers, or simply stop using certain email addresses.

This means that when someone signs up for your mailing list, they receive an email asking them to confirm their subscription. This helps to ensure that the email address is valid and that the person wants to receive your emails.
Finally, don't be afraid to clean your email list regularly by removing invalid email addresses. This can help to improve your email deliverability and reduce the likelihood of your emails being marked as spam.

Step 5: Authenticate Your Emails

Have you ever sent an email and wondered if it actually landed in your recipient's inbox? Well, email authentication can help ensure that your emails are delivered and not marked as spam or phishing attempts.
Email authentication is the process of verifying that an email is actually from the sender it claims to be from. This is important for deliverability because email providers, such as Gmail or Outlook, use authentication to help determine whether to deliver an email to the recipient's inbox or send it to the spam folder.
There are a few different methods of email authentication, but the most common are SPF, DKIM, and DMARC. SPF (Sender Policy Framework) allows the sender to specify which IP addresses are authorized to send emails on behalf of their domain. DKIM (DomainKeys Identified Mail) uses digital signatures to verify that the message was sent by the authorized sender and hasn't been modified in transit. DMARC (Domain-based Message Authentication, Reporting, and Conformance) is a policy that uses both SPF and DKIM to determine how to handle unauthenticated emails.
Why is email authentication important for deliverability? Well, without authentication, your emails may be rejected by email providers, marked as spam, or sent to the recipient's junk folder. This can decrease your open and click-through rates, and even damage your reputation as a sender. By using email authentication, you can help ensure that your emails are delivered to the intended recipients, build trust with your audience, and protect your brand's reputation.
Tips for authenticating your emails, such as using SPF, DKIM, and DMARC
Authenticating your emails is super important to make sure they're delivered to your recipients' inboxes and not sent to spam. Here are some tips to help you authenticate your emails:
- Use SPF (Sender Policy Framework): SPF allows you to specify which IP addresses are authorized to send emails on behalf of your domain. This can help prevent spammers from sending fake emails from your domain. To use SPF, you need to add a DNS record that lists the IP addresses that are allowed to send emails from your domain.
- Use DKIM (DomainKeys Identified Mail): DKIM uses digital signatures to verify that the message was sent by the authorized sender and hasn't been modified in transit. To use DKIM, you need to add a DNS record that contains a public key used to verify the digital signature.
- Use DMARC (Domain-based Message Authentication, Reporting, and Conformance): DMARC is a policy that uses both SPF and DKIM to determine how to handle unauthenticated emails. It allows you to specify how you want email providers to handle emails that fail SPF or DKIM checks. You can choose to have the emails be delivered, marked as spam, or rejected.
- Use a reliable email service provider: Many email service providers, like Gmail or Mailchimp, automatically authenticate emails using SPF, DKIM, and DMARC. By using a reliable email service provider, you can ensure that your emails are properly authenticated and have a higher chance of being delivered to your recipients' inboxes.
- Monitor your email authentication: It's important to regularly monitor your email authentication to ensure that it's working correctly. You can use tools like DMARC Analyzer or dmarcian to monitor your DMARC reports and make sure that your emails are being properly authenticated.
In summary, authenticating your emails is crucial to ensure that they're delivered to your recipients' inboxes and not marked as spam. By using SPF, DKIM, and DMARC, and a reliable email service provider, you can improve your email deliverability and protect your brand's reputation. Don't forget to regularly monitor your email authentication to ensure that it's working properly!
