Your 'Valid' Emails Are Lying to You

Your verifier says an email is "valid." We tell you if it's safe. Allegrow goes beyond basic email validation, assessing for hidden risks like spam traps and known complainers, and providing "safe"/"risky" responses for catch-all verification.

Includes 1,000 free email risk assessments. No credit card required.

What Your Email Verification Tool Isn't Telling You

Your Data is Full
of Traps

Your list is a minefield of threats basic email verifiers can't see. You're guessing which of your catch-all addresses are safe, while spam traps, known complainers, and disposable emails are waiting to be sent. Every campaign is a gamble with your domain.

Silent Domain
Degradation

One wrong move—hitting a single spam trap or getting one too many complaints—and your domain gets flagged. Suddenly, all your emails start going to spam, and you have no idea why. You're left trying to fix a problem you can't see, long after the damage is done.

Your Budget is Being
Wasted

You're paying for a model that's designed to fail. Besides penalizing you for having a large list, credit-based tools punish you for cleaning often and force you into one-off scrubs that are useless in weeks. With constant data decay, their "solution" simply doesn't work.

Verify Every Email with Absolute Confidence

Allegrow is an automated email deliverability tool that runs in the background neutralizing threats so your team can confidently send emails without hurting outreach.

Here's how you'll win back your pipeline:

Connect Your Stack in Seconds

Securely link your stack to our email deliverability platform in just a few minutes. Our native, SOC2-compliant integrations mean no complex setup and no insecure app passwords. Just one click to connect.

Instantly See Your Real Risk

Go beyond "valid." We instantly scan every contact for 30+ risk factors, exposing the spam traps, known complainers, and reputation threats that basic email validators can't see.

Protect Your Pipeline Automatically

Once connected, Allegrow's Safety Net™ automatically blocks or reroutes high-risk contacts before your reps hit send, safeguarding your domain reputation and ensuring every critical message lands in the primary inbox.

Stop Paying for "Valid". Start Investing in Safe.

Workvivo 3x'd Their Reply Rates

"I strongly believe if you don't have a product to monitor and improve inbox placement, your investment in other technologies like ZoomInfo and Outreach is wasted because your reps' messaging isn't being seen [...] With Outreach campaigns, we've seen our reply rates increase by 200-300% using Allegrow."

Richard Mullins

Head of Global Business Development, Workvivo

Emails to clients were landing in spam. Not anymore!

"The biggest issue we had was that employees who were even emailing current clients were still landing in the spam folder... Before, we had a lot of worries about our Head of Product sending a bottom-of-funnel lead key information and it was going to spam. This has been eliminated by utilizing Allegrow."

Alexander Koogan

Director of Finance, Spring Labs

Calendar Invites Were Going to Spam. Now It's Not a Concern.

"Previously ADMs would struggle to send even a calendar invite to a prospect they were engaged with, without it ending up in the spam folder. This would happen on a weekly basis. Now we're a year into using Allegrow, and it's not a concern I hear anymore."

Your Deliverability Questions, Answered

No. Verifiers see if an email can receive messages. We tell you if it's safe to send. They see if an email exists; we see if it's a known spam trap or a habitual spam reporter that will get your domain blacklisted.

Perfect. Setup takes 15 minutes. Allegrow runs in the background of platforms like Outreach and Salesloft, protecting your team without them ever needing to change their workflow.

That's what most of our customers thought, too. Domain damage happens silently before it becomes a crisis. A free 1,000-contact risk analysis with our 14-day trial will show you the hidden risk you're carrying right now.

Under no circumstances. We never send emails to verify a catch-all address. That method is risky, outdated, and often gives you false confidence.
Instead of guessing or scraping online sources like basic tools, Allegrow uses a proprietary, signal-based system to analyze each individual contact on a catch-all domain. This tells you which specific emails are safe to send to and which are engagement dead zones or hidden risks. You stop gambling on 30% of your list and start having conversations.

Absolutely not. The new rules are about your ongoing sender reputation, not just one-time validation. Allegrow is built for this reality. We continuously monitor your domain health and spam placement, ensuring you stay compliant and protected long-term, so you never have to worry about a sudden shutdown.

You get immediate access to the Allegrow platform for 14 days. Right away, you can upload your first list of up to 1,000 contacts and start seeing the hidden spam traps and risky catch-alls in your data.
To set you up for success, one of our deliverability specialists will contact you and schedule a strategy session, helping you get the most value and insight from your trial.
