In the Ultimate Guide to Email Deliverability, we’ve already discussed what email deliverability is, why you need to regularly monitor it, and looked through the process of email deliverability audit from the inside out (if you haven’t read our guide yet, just do it).
But there’s something else a business email sender needs to know… and have on hand – special tools that will help keep email deliverability high-top.
Last time I only mentioned some of them. In this post, I suggest we talk about email deliverability software more precisely so you can choose your personal toolset and boost your email-sending confidence.
So, what is an email deliverability tool?
Email deliverability tool definition

Email deliverability tools provide features such as technical email setup, email warm-up, bounce rate and email engagement tracking, DMARC reporting, recipient validation, sender reputation management, ready-made templates, and other guidance — all to increase your inbox placement.
As a rule, email deliverability software integrates with email marketing and testing tools. It can also be a part of more sophisticated marketing automation platforms that offer abundant features for growing email deliverability and enhancing overall email marketing performance.
Why use an email deliverability tool?
The top reason for using an email deliverability tool is that it helps you land right in the recipient’s Inbox, avoiding Spam and Promotions tabs. With it, you can:
- Set up your email account so it becomes more email service provider friendly.
- Understand what actions of yours as a sender trigger spam filters and improve them.
- Keep your sender reputation and email deliverability optimal thanks to analytics and timely suggestions.
Email deliverability software not only automates the processes and ensures high inbox placement but also provides guidance on becoming a confident and professional email sender.
Top 12 tools to optimize your email deliverability
Now let’s discuss the best tools to grow your email deliverability based on the features I mentioned at the beginning of the post.
As you’re reading the Snov.io blog, you might be curious whether this service can assist you in growing your deliverability. It surely can! Here’s how.
Known as an all-in-one platform for sales automation and a free CRM with an integrated email outreach service, Snov.io has recently launched a new feature – Email Warm-up – that is bound to help email senders grow email deliverability no matter how old their email account is.
The tool allows you to choose your settings and warm-up strategy, automatically sends and replies to emails on your behalf, imitates real conversations thanks to the AI-powered mechanism, and unspams your emails to ensure perfect inbox placement. As a result, you can already enjoy your email deliverability improvement after 2-3 weeks of warm-up.
Apart from the warm-up functionality, Snov.io offers an email verification tool that checks your email list for validity and guarantees you’re not sending emails to non-existing addresses, preventing you from bounces, low delivery rate, and damaged reputation.
On top of that, Snov.io has a collection of templates tailored for your email content optimization – a thing often overlooked, though crucial for email deliverability.
Snov.io offers a forever-free plan so that you can test its functionality and find your pace. The basic paid plan starts at $39/month and includes a big package of features: Email Warm-up, Email Verifier, Email Finder, Email Drip Campaigns, and a free CRM.
Mail-tester is one of the most popular tools to check how well your email account is prepared for hitting the user’s Inbox. The service analyzes your email message to ensure each element of your email campaign favors high deliverability. All you need to do is send an email from your domain to the unique email address generated by Mail-tester.
Upon receiving your email, the tool will rate your email deliverability on a scale from 1 to 10 and provide you with a detailed report, displaying your SpamAssassin rating, informing you whether you’re properly authenticated, and showing you how your message can be improved.
Mail-tester checks whether your SPF and DKIM are set up and valid. You can do this quick analysis without sending an email by simply entering your domain name and DKIM Selector right on the Mail-tester’s website.
Mail-tester is a free tool for manual testing. You don’t need to create an account. If you wish to integrate test results into your application or have a list of all tests performed within the last 30 days, you’ll need to make an account. The basic price for 500 tests, in this case, is around $50.
MxToolbox is a complex solution for email deliverability issues. It’s easier to say what tests the tool doesn’t perform than what tests it runs. By default, the service will let you look up MX records against any given domain. But you can run dozens of tests such as SPF record, DMARC, DKIM lookup, Blacklist Check, and more.
The Email Health Check will execute hundreds of domain/email/network performance tests to ensure your systems are online and performing optimally. The report will then highlight critical areas for your domain that need to be resolved, including blacklist, mail server, web server, and DNS issues.
MxToolboxl can do an email header analysis for you, checking your email headers for readability. Simply paste your email header, and the tool will do the rest.
MxToolbox offers a free plan, though it’s limited to blacklist monitoring only. If you want to run other tests, you can choose between two paid plans – Delivery Center at $129/month for monitoring 5 domains and 500 messages or Delivery Center Plus at $399/month for monitoring 5 domains and 5,000,000 messages.
Litmus cares about your email deliverability by running pre-send email testing for you. The tool checks links, images, and other critical elements to optimize your email for more opens and conversions.
Additionally, Litmus does spam testing. It checks your email infrastructure (DKIM, SPF, and DMARC records), analyzes IP addresses and domain names against common blacklists, scans your email across popular spam filters, and provides practical advice on how to fix issues and improve your email deliverability, so you can generate the best possible results.
Litmus doesn’t have a free plan but offers a 7-day free trial for you to test its features. The basic pain plan costs $79/month.
Folderly is an all-in-one platform for boosting your email deliverability. With this tool, you can easily run an email deliverability audit, whereby it analyzes your domain and mailbox performance and health scores, helps you improve email authentication, runs blacklist scans, and provides recommendations on how to fix and prevent any email delivery-related issues.
Additionally, with Folderly, you can test your inbox placement to see where your emails land – in Inbox, Promotions, or Spam – and look into the content of your cold email templates for spam trigger words.
Folderly also offers an email warm-up tool to prepare your fresh domain to hit the Inbox. Boasting advanced email warm-up algorithms, it promises to make you a credible email sender within just 2 weeks.
Folderly doesn’t offer free options. You can either buy its features separately (Email Warm-Up will cost you $49/month, while for Email Deliverability Test, you’ll need to pay $129/month) or purchase a single Cold Email Outreach package at $200/month, which will include all features for improving email deliverability.
Sender Score is the tool for checking your sender reputation. Although there’s nothing extraordinary about this service, the solution is absolutely free and copes with its basic functions well: it evaluates your domain reputation based on such factors as email volume, the number of complaints, external reputation, rejected messages, and more.
You just need to enter your IP address and company information, and the tool will generate your sender score (from 0 to 100) based on how mailbox providers view your IP address.
If your sender score is below 70, you need to repair your sender reputation. A score from 70 to 80 means you should continue following industry best practices and optimizing your email program. A score above 80 indicates your sender reputation is great.
