Clickback vs Prospeo: They're Not Competitors - Here's What You Actually Need
This comparison is a category mismatch. One tool sends emails to a list you already have. The other builds the list from scratch. We built Prospeo, so we know it inside out - but we'll be fair about what Clickback does well and where it falls short.
30-Second Verdict
Clickback is a cold email sending and list hygiene platform (plus a website visitor intelligence product). Prospeo is a B2B data platform for finding and verifying contacts.

Need to find prospects? Prospeo wins outright. Already have a purchased cold list and need compliance-focused sending infrastructure? Clickback has a niche - but most teams are better off pairing verified data with a dedicated sending tool like Smartlead or Instantly.
Skip Clickback MAIL if you don't have a list yet, need mobile numbers, or want self-serve sending under $300/month.
What Is Clickback?
Clickback runs two separate products.
Clickback MAIL takes a cold contact list, runs it through roughly 20-30 checks on import, and sends campaigns using dedicated IPs and domains to protect your sender reputation. Clickback WEB identifies anonymous companies visiting your site and lets you purchase key contacts at those companies for follow-up. Their pitch: on average only 6% of website visitors ever inquire, so Clickback helps you reach the other 94%.
If you have fewer than 17,500 contacts or more than 150,000, you'll need to contact their sales team for pricing.
What Is Prospeo?
Prospeo is a B2B data platform with 300M+ professional profiles, 143M+ verified emails, and 125M+ verified mobile numbers. Email accuracy sits at 98%, and every record refreshes on a 7-day cycle - the industry average is closer to six weeks, which tells you how stale most competitor data gets between updates.
You get 30+ search filters covering buyer intent, technographics, job changes, headcount growth, funding, and revenue. A Chrome extension with 40,000+ users pulls verified contact data from any website or CRM. Intent data powered by Bombora tracks 15,000 topics so you can prioritize accounts showing buying signals. Native integrations push contacts directly into Salesforce, HubSpot, Smartlead, Instantly, Lemlist, Clay, Zapier, and Make.


Why pay $300/month to send to a list you already have? Prospeo gives you 300M+ profiles with 30+ filters, 98% verified emails, and 125M+ mobile numbers - then pushes them straight into Smartlead or Instantly. Build the list and send for a fraction of what Clickback charges.
Start with 75 free verified emails. No contract, no sales call.

Pricing Breakdown
Clickback MAIL (pricing page):

| Plan | Monthly Cost | Total Emails/Mo (sent + cleaned) |
|---|---|---|
| Starter | $300 | 25,000 |
| Essential | $400 | 50,000 |
| Premium | $600 | 100,000 |
| Enterprise | ~$1,000-$5,000+ | 5M+ |
Here's the catch: "Total Emails" means emails sent plus emails cleaned. If you clean 20,000 contacts and send to 15,000, that's 35,000 total - you're already on the Essential plan at $400/month. That billing model adds up fast.
Clickback WEB (pricing page):
| Plan | Monthly Cost |
|---|---|
| Small Business | $99 |
| Medium | $225 |
| Large | $350 |
Running both products costs $399-$950/month, with higher tiers available for enterprise. Prospeo works differently: roughly $0.01 per verified email, a free tier with 75 verified emails and 100 Chrome extension credits monthly, no annual lock-in, and no sales call required.
Which Tool Should You Choose?
You need to find prospects. There's no contest here. Clickback MAIL has no prospecting database. Prospeo's 300M+ profiles with 30+ filters let you build targeted lists in minutes, and you're only paying for contacts that pass verification.

You have a cold list and need compliant sending. Clickback has a niche, but let's do the math. At $300-$600/month locked into a 12-month agreement, you're spending $3,600-$7,200/year on sending infrastructure alone. In our experience, most teams get better results pairing verified data (which rarely bounces) with Smartlead or Instantly at a fraction of the cost. Meritt tripled their pipeline from $100K to $300K/week after making that switch, with bounce rates dropping from 35% to under 4%.

You want website visitor tracking. Clickback WEB does this. Worth noting though: Capterra reviewers flag that the visitor and company data isn't always accurate because it only surfaces companies already in Clickback's database. Reviews also mention a dated interface and frustration managing multiple campaigns - fine for a single product, painful at scale.
Here's the thing: if your average deal size is under $25k, you almost certainly don't need Clickback's compliance-heavy sending infrastructure. Verified data plus a $30/month sending tool will outperform a $400/month Clickback plan every time.
One more market signal. Clickback has 13 G2 reviews and 11 on Capterra, and its G2 profile hasn't been active for over a year. There's virtually no Reddit discussion about it either - another indicator of limited adoption in the broader sales community.

Meritt dropped their bounce rate from 35% to under 4% and tripled pipeline to $300K/week - not by paying more for sending infrastructure, but by switching to data that's actually verified. At $0.01 per email with a 7-day refresh cycle, you skip the list hygiene step entirely.
Stop cleaning bad lists. Start with data that's already clean.
FAQ
Is Clickback a prospecting database?
No. Clickback MAIL is a cold email sending and list hygiene platform - you bring your own contacts. It doesn't have a searchable B2B database. If you need to build prospect lists from scratch, you need a dedicated data provider.
Can I use Clickback and Prospeo together?
You could, but most teams prefer pairing verified contact data with a sending tool like Smartlead or Instantly. Lower cost, no 12-month lock-in, and the data's already clean at 98% accuracy so you're not paying Clickback to re-verify what's already verified.
How much does Clickback cost per month?
Clickback MAIL starts at $300/month on a 12-month agreement. Add WEB ($99-$350/mo) and you're at $399-$950/month. Prospeo's free tier includes 75 verified emails monthly, with paid plans at roughly $0.01 per email - no contract required.
What's the main difference between Clickback and Prospeo?
Different categories entirely. Clickback MAIL sends emails to lists you already have. Prospeo finds and verifies the contacts in the first place - 300M+ profiles, 98% email accuracy, and a free tier to start with.
