Our Verdict — Best Of The Best

Price: Starts at $49/month

Warmy is an automated email warming tool that actually improves deliverability. We think it’s the best because of its multilingual warm-up capabilities, mailbox health checks, and topic-specific warm-up feature.

The Best Part:

  • Test deliverability across multiple platforms. Warmy lets you quickly check where your messages land across various email providers, giving you all the insights you need to land your emails in more inboxes.

The Worst Part:

  • No ongoing free option. Warmy offers a 7-day free trial, but there isn't a lasting free plan for users who want long-term basic access to its email deliverability tools without a paid subscription.

Get it if you want a smart solution for boosting email deliverability rates through AI-generated personalized messages and real mailbox interactions.

I recommend you start with the 7-day free trial, then get the Starter plan for $49/month.

(7-day free trial)

Best For

Top Features

Our Verdict — Best For Email List Cleaning

Price: Starts at $10 for 5,000 verifications

DeBounce is a comprehensive email validation and verification solution designed for businesses aiming to clean and maintain healthy email lists. We think it’s the best for email list cleaning because of its effective bouncing email minimizer, disposable email checker, and its unique anti-greylisting technology.

The Best Part:

  • It’s all about validation. DeBounce offers a comprehensive email verification process that makes sure only valid emails make it to your list. The cherry on top? Its syntax eliminator feature helps eradicate email addresses with invalid syntax, keeping your list clean as a whistle.

The Worst Part:

  • Restricted API. DeBounce's API, unlike some competitors, can't stop validation mid-process or request anti-greylisting, which can be a drawback for some users.

Get it if you want a one-stop solution for maintaining a clean email list, removing duplicate and invalid email addresses, and increasing your email deliverability rate.

I recommend you start with the 5,000 Verifications plan for $10.

(97.5% deliverability guarantee)

GlockApps is an all-in-one email deliverability toolkit designed for businesses that require detailed deliverability audits. We think it’s the best for detailed deliverability audits because of its comprehensive spam testing, in-depth deliverability insights, and reliable blacklist monitoring.

The Best Part:

  • In-depth deliverability insights. GlockApps provides actionable improvement tips and comprehensive reports to help you quickly pinpoint issues and optimize your email campaigns.

The Worst Part:
