How to set up real time email verification in Verifybee

If you’re tired of fake signups, bouncebacks, and junk emails clogging up your CRM, you’re in the right place. This guide is for anyone who wants to set up real-time email verification using Verifybee. Whether you’re a marketer, a SaaS founder, or just the unlucky soul stuck cleaning up messy data, I’ll walk you through the whole thing—step by step, no jargon, and zero hand-waving.

Why Bother With Real-Time Email Verification?

Let’s be honest: most people don’t type in their email wrong by accident. Some are just testing, some want your freebie but not your emails, and a few are bots. If you’re letting every address straight into your list, you’ll end up paying for dead contacts, hurting your sender reputation, and wasting time.

Real-time verification means checking if an email is valid before it hits your system. Done right, it’s as close as you’ll get to a “clean list” from day one. Is it perfect? No. But it’s a massive step up from nothing.

What You’ll Need

Before you start, make sure you have:

  • A Verifybee account (even a trial will work)
  • Access to your website or signup form code (or whatever tool you use for lead capture)
  • 15–30 minutes to focus (it’s not complicated, but don’t rush)

Step 1: Sign Up for Verifybee (If You Haven’t Already)

  • Go to Verifybee.
  • Sign up with your work email.
  • Confirm your account via the link they send you. (Yes, they eat their own dog food here and verify you.)
  • Log in and poke around. Get familiar with the dashboard.

Pro tip: Don’t overthink the plan level. Start with the free or lowest tier—upgrade only if you actually need more verifications.

Step 2: Get Your API Key

Everything in Verifybee runs through their API. Here’s how to find your credentials:

  1. In the dashboard, look for “API” or “Developers” in the sidebar menu. (If they’ve moved it, check your account settings.)
  2. Copy your API key. It’ll be a long string of letters and numbers.
  3. Store this somewhere safe. Don’t put it in public code repos or client-side JavaScript.

Why does this matter?
You’ll use this key to tell Verifybee “Hey, this email is trying to sign up—can you check if it’s real?”

Step 3: Decide Where to Integrate Verification

You have two choices here:

  • Client-side: Validate emails as soon as a user types them in (in the browser, before the form submits).
  • Server-side: Validate emails after the form submits, on your backend.

My take:
Client-side is nice for instant feedback (“Whoops, that’s not a real address!”), but it exposes your API key—not good. Server-side is more secure, and you’ll catch bots/scripts that bypass the UI. If you care about data quality, always do server-side verification, even if you add client-side for the user experience.

Step 4: Connect Verifybee to Your Signup Form

Option A: Use a Native Integration (If Available)

Check if your form tool (like Zapier, HubSpot, or Webflow) has a ready-made Verifybee integration. This saves a ton of time.

  • In Verifybee, check for “Integrations” or “Apps.”
  • Follow the prompts to connect your tool.
  • Map the email field from your form to Verifybee.
  • Set the integration to “verify in real time” or “validate on submission.”

Honest take:
Native integrations are great—when they exist. But not every tool is supported, and sometimes these integrations are slow to update or a pain to debug. Test thoroughly.

Option B: Use the API Directly (Code Required)

If you’re working with custom forms (like in React, Laravel, or plain HTML), you’ll need to call the Verifybee API yourself.

Here’s a basic server-side example (Node.js/Express):

javascript const axios = require('axios');

app.post('/signup', async (req, res) => { const email = req.body.email; try { const response = await axios.post( 'https://api.verifybee.io/v1/email/verify', { email }, { headers: { 'Authorization': 'Bearer YOUR_API_KEY' } } ); if (response.data.status === 'valid') { // Save user, send welcome email, etc. res.status(200).send('Signup successful!'); } else { // Block signup, show error message res.status(400).send('Please use a real email address.'); } } catch (error) { // Fallback: let user know something went wrong res.status(500).send('Verification service error.'); } });

Key points: - Replace YOUR_API_KEY with your actual Verifybee API key. - Don’t call the API from the browser (security risk). - Handle errors gracefully—Verifybee can go down, so have a backup plan.

Pro tip:
Don’t only check if the address is valid—log the responses. If you notice a ton of “catch-all” or “unknown” results, you’ll want to review if your gatekeeping is too tight (or too loose).

Step 5: Handle the API Response

Verifybee’s API usually returns one of these statuses:

  • valid: The email exists and should work.
  • invalid: The email doesn’t exist or is known bad.
  • catch-all: The domain accepts all emails, so Verifybee can’t be sure.
  • unknown: Couldn’t check (mail server didn’t respond).

What to do:

  • valid: Let the user through.
  • invalid: Block signup, show a friendly error.
  • catch-all/unknown: Use your judgment. For most, it’s fine to allow these but maybe flag them for review. If you’re super strict, block them—but you’ll get some false positives.

Pro tip:
Don’t punish users for a single typo. Show clear, non-judgy error messages (“Hmm, that didn’t look like a real email. Mind double-checking?”).

Step 6: Test Everything (Don’t Skip This)

  • Try signing up with your real email, a fake one (fakeaddress@notreal.com), and a typoed one (gmal.com instead of gmail.com).
  • See how your system handles each case.
  • If you’re using both client and server-side checks, make sure both work.
  • Watch out for rate limits or timeouts from Verifybee—don’t hammer their API in a loop.

Heads up:
No verification service is 100% accurate. Some domains are sneaky, and some free mailbox providers are just weird. Always test with real-world scenarios.

Step 7: Monitor and Adjust

  • Keep an eye on your signup logs for odd patterns (lots of “catch-all,” sudden drops in “valid” emails, etc.).
  • If you notice good users getting blocked, loosen up.
  • If spam is still sneaking through, tighten your filters.
  • Review your Verifybee usage so you don’t get hit with surprise bills.

Pro tip:
Set up alerts for API errors or spikes in failed verifications. Better to catch issues early than clean up a mess later.

What Not to Waste Time On

  • Don’t obsess over catching every single fake email. You’ll never get to zero.
  • Don’t expose your API key in client-side code. Even if a blog post says it’s fine, it’s not.
  • Don’t rely solely on email verification for security. Use double opt-in or CAPTCHA if you’re fighting serious bots.

Wrapping Up (Keep It Simple)

Getting real-time email verification set up in Verifybee isn’t rocket science, but you do need to pay attention to the details. Start small: wire up your signup form, test your flow, and tweak as you go. Don’t worry about being perfect. You’ll catch most junk, and your inbox (and team) will thank you.

The best advice? Keep it simple, ship it, and iterate. If something’s not working, you’ll see it in your data—and you can fix it then.
