Picture this: you’ve warmed up your email domain and configured your DNS settings. Your copy is excellent, full of personalization, and free of SPAM-triggering words. The first batch of marketing messages goes out…and a lot of them come back as undeliverable. There were two critical steps missing in your process: testing email deliverability and verifying the email addresses.
TL;DR
- Email deliverability is different from email delivery. Deliverability focuses on reaching the inbox without being marked as spam, while delivery refers to sending the email to its destination.
- Factors that affect whether your emails reach the inbox include sender score, domain reputation, email authentication protocols, content quality, and recipient engagement.
- Domain reputation is a measure used by email service providers (ESPs) and spam filters to assess the reputation of the domain from which your email is sent and has a direct impact on the results of your outbound or email marketing activities.
- You should do a spam check before and during your cold email campaigns to prevent landing in spam folders.
- Types of deliverability tests include authentication, content spam checkers, comprehensive deliverability reports, and seed lists.
- Tools you can use to do these tests include SendForensics, GlockApps, MailTester, Warmbots, Mailook, Sendpost, MxToolBox, Mailtrap, SenderScore, CheckMX, and Spamhaus.
- Each tool has advantages and disadvantages considering the features offered, ease of use, and pricing.
- If you suspect your domain is blacklisted, you can check with blacklists like Spamhaus or use email deliverability testing tools.
- Taking tactical anti-spam measures can have a positive impact even if your domain is not blacklisted.
- Good deliverability rate is important for businesses and individuals as it increases the chances of emails being read and acted upon.
- Using a tool like Growbots can simplify the process of finding real users and verified email leads, monitoring deliverability, and improving outreach campaigns. Test it out for free.

What is Email Deliverability?
Email deliverability is all about whether your emails actually make it to your recipients’ inboxes or end up in the spam folder. Basically, it’s the measure of how successful your emails are at reaching their destination without getting flagged as spam or blocked by filters.
There are a couple of things that affect deliverability of your emails: sender score, domain reputation, email authentication protocols, content quality, and how engaged your recipients are.
Good email deliverability is super important for businesses and individuals because it ensures that your messages get through and have a better chance of being read and acted upon.
You might be wondering if email deliverability and email delivery are one and the same.
Well, they’re actually different, and here’s why: email deliverability is all about the success and ability of an email to reach the recipient’s inbox without being flagged as spam.
On the other hand, email delivery simply refers to the act of sending an email to its intended destination, without considering its final outcome or whether it lands in the inbox or spam folder. So, while they may sound similar, they have distinct meanings when it comes to the journey of your emails.
Taking this under consideration, if you want to make the most of your outreach and keep that communication flowing smoothly, you should focus on testing email deliverability and optimizing it for better results.

When to Test Email Deliverability
There are various factors tagging whether your email will land in the receiver’s inbox or spam folder. Email deliverability is basically the email placement. What are the cases you need to test it?
- Before your cold email campaign
- During your cold email campaign
The first case, that is before your cold email campaign, is when you need to test if the campaign is automated. The second one is required only if you presume low email deliverability, get blocked, or land in the spam folder too much, so you need to increase your sender reputation and conduct regular spam checks.
Your sender’s score depends on many factors, so make sure to engage in email deliverability testing as a part of each campaign.
Based on this, there are a few types of email deliverability tests:
- authentication (the proper configuration of the outgoing email server)
- content spam checkers (it is a spam check of the content – checking whether the message will be caught by spam traps by email service providers due to spam-triggering words)
- email deliverability test (comprehensive deliverability reports on delivery rates)
- seed list (to check out what will happen to the emails you send to various subscribers who use different inbox providers, ISPs, browsers, and devices)
All of these methods to easily test email deliverability can hook any email deliverability and spam issues at an early stage, so you are able to react on time.

What if I Suspect My Domain Is Already Blacklisted?
If you’ve already had a lot of hard bounces or your email campaigns are performing poorly, you can check to see if your domain or IP addresses are blocklisted. It’s often possible to conduct an email deliverability check directly with a blacklist, like Spamhaus, or use other email deliverability testing tools like Mailgenius, GlockApps and MX Toolbox.
Blacklists have different steps to request removal. If a blacklist has damaged your domain or IP reputation, you may benefit from going through an email warmup process again.
Not blacklisted and still having trouble? You may need to take some tactical anti-SPAM measures that can help with avoiding spam filters and improving email deliverability.
Why you need to care about email deliverability
No matter if you are a small business owner looking to grow your business or a professional sales rep conducting outreach on a daily basis, prioritizing email deliverability is absolutely crucial.
Why?
Because your cold emails serve as the gateway to new opportunities and potential clients.
When your emails successfully land in recipients’ inboxes, you greatly enhance the chances of capturing their attention and piquing their interest. However, if your email deliverability is subpar, your messages may end up lost in the dreaded spam folder, severely reducing the likelihood of being opened and read by your intended audience.
Neglecting email deliverability can have serious consequences, including the possibility of your email account being banned or flagged as spam.
It’s imperative to make a positive first impression, foster trust, and ultimately drive business growth. By proactively optimizing your email deliverability, you can significantly improve the impact of your cold emails and empower your business to thrive.
