Key Features to Consider in an MxToolbox Alternative

Woman showing tools - mxtoolbox alternative

Before switching to a MxToolbox alternative, find out how well the tool can check where your emails are landing. An inbox placement feature will tell you if your emails are landing in the:

Primary inbox
Spam folder
Promotions tab
Going missing altogether

This is crucial because it helps you understand where your emails are being delivered. Remember that emails sent via these tools are essentially cold emails, as they never generate any interactions. Your real deliverability rate will likely be higher than these email deliverability testing tools indicate.

Prevent Your Emails From Getting Stuck in the Spam Folder

A spam checker analyzes your email content and structure to identify elements that might trigger spam filters, such as spammy words or poorly formatted HTML. This way, you can improve your emails so they don’t end up in the spam folder.

Check Your Authentication With an Authentication Checker

Some email deliverability tools offer this feature to check that your emails have proper authentication (like DKIM, SPF, and DMARC). Verifying that your emails are legitimate and not forged increases the likelihood that they will be delivered successfully.

Monitor Your Sender Reputation

Reputation monitoring checks the reputation of your sending IP addresses (whether shared or dedicated) and your domain. This feature looks for blacklists or negative scores that might harm your email deliverability and suggests ways to improve your sender reputation.

Reduce Bounces With Email Validation

Email validation verifies the accuracy and validity of email addresses on your list, reducing the chances of sending emails to invalid or non-existent addresses, which can hurt your sender’s reputation.

Simulate Engagement to Improve Deliverability

Engagement simulation interacts with your emails in ways that real users would, like opening and marking them as essential to help build a positive sender reputation and improve future deliverability. Some email deliverability software tools offer this as part of their service.
