Clickback vs SMARTe: Different Tools for Different Problems
If you're weighing Clickback against SMARTe, here's the first thing to understand: these two tools barely overlap. Clickback is a cold email sending platform built for purchased lists. SMARTe is a sales intelligence database built for enrichment and direct dials. Already have a list and need to send legally? That's Clickback territory. Still hunting for dials and emails? Clickback won't help - that's SMARTe's job.
Here's the thing, though. Most teams comparing these two actually need neither. Their real bottleneck is bad data - stale emails, dead phone numbers, bounced sends - and that's a problem upstream of both tools.
30-Second Verdict
Use Clickback if you're sending cold email to purchased or rented lists at scale and need compliance gating (CAN-SPAM, CASL, GDPR) baked into the sending layer.
Use SMARTe if you need sales intelligence - emails, direct dials, and company data pushed into your CRM for outbound prospecting (and a broader sales prospecting database behind it).
Skip both if your real bottleneck is verified contact data with guaranteed freshness. Clickback sits at 3.1/5 on Trustpilot while SMARTe holds a 4.6/5 on G2, but both ratings are based on just 24 reviews each. Treat them as directional, not definitive.
What Each Tool Actually Does
Clickback
Best for: Marketing teams sending to purchased or rented lists who need compliance guardrails.
Clickback markets a 287-point deliverability check that strips honeypots, spam traps, and invalid addresses before a single email goes out. The compliance layer handles CAN-SPAM, CASL, and GDPR. There's also a Website Visitor Intelligence (WVI) module that identifies anonymous companies visiting your site via a tracking snippet (similar to how email tracking pixels work under the hood). CRM integrations cover Salesforce, Zoho CRM, and Pipedrive.
It's a narrow tool. It doesn't find contacts. It doesn't enrich records. It sends email to lists you already have.
SMARTe
Best for: Sales teams that need net-new contacts, direct dials, and CRM enrichment with buying signals.
SMARTe's database covers 229M+ contact profiles across 60M+ companies, with roughly 70% mobile number availability in North America. A Chrome extension lets reps pull emails and direct dials while browsing professional profiles and company websites. ICP filtering includes job role, seniority, industry, company size, revenue, and technographic attributes (see firmographic and technographic data). Buying signals like funding announcements, leadership changes, and company growth are gated to higher tiers (more on identifying buying signals). Integrations run deeper than Clickback's: Salesforce, HubSpot, Outreach, Salesloft, and Microsoft Dynamics. SMARTe is GDPR, CCPA, and SOC2 compliant.
The gap between these two isn't subtle. They serve different stages of the pipeline entirely.

Quick Decision Tree
- You already have compliant lists and need to send at scale: Clickback
- You need net-new contacts, direct dials, and CRM enrichment: SMARTe
- Bounce rates and data decay are killing your deliverability: Prospeo (98% email accuracy, 7-day refresh cycle) - start with email deliverability fundamentals
- Your RevOps team can't support dedupe rules yet: Avoid auto-enrichment until configured; start with manual reveals (use a lead enrichment workflow first)
Clickback charges $300+/mo to send to lists you already have. SMARTe charges $0.50/credit to reveal contacts. Prospeo gives you 300M+ verified profiles, 125M+ mobile numbers, and 98% email accuracy - all refreshed every 7 days - for roughly $0.01 per email. No annual contracts, no cancellation nightmares.
Stop paying two tools for what one data layer handles better.
Pricing Breakdown
| Plan | Clickback | SMARTe |
|---|---|---|
| Free/Entry | 14-day trial | $0 (10 credits/mo) |
| Starter | $300/mo (25K emails sent or cleaned) | $25/user/mo (Pro) |
| Essential | $400/mo (50K emails/month) | $0.50/credit (Pro) |
| Premium | $600/mo (100K emails/month) | $0.30-$0.20/credit (Enterprise, 50K-1M volume) |
| Enterprise | Custom | Pay-per-credit, no license fees |
Comparing these prices side-by-side is misleading because the units are completely different. Clickback is priced by monthly send volume. SMARTe is priced by credits - each contact reveal costs credits.
Let's do the math on SMARTe. If you reveal 1,000 contacts per month on Pro at $0.50/credit, that's $500 in credits plus the $25 base - $525/month for data alone. At Enterprise volume with 1M credits, the per-credit cost drops to $0.20, but you're committing to serious scale.
We've seen teams waste weeks comparing dollar-per-month across tools that price on totally different units. Map cost to contacts revealed or emails sent instead. That's the only comparison that holds up (and it’s also how to evaluate data enrichment services).
What Users Actually Complain About
Clickback
Reviewers on Trustpilot praise the onboarding process and support team responsiveness. But the 3.1/5 score tells a story.
The loudest complaints center on a 12-month contract lock-in - multiple reviewers describe cancellation attempts lasting months with continued billing. Deliverability issues come up repeatedly despite the 287-point check, and the interface gets called "antiquated." One reviewer found that attempting to unsubscribe triggered 20 emails a day instead of fewer. If a tool makes cancellation hard, that tells you exactly how confident they are you'll renew voluntarily.
SMARTe
G2 reviewers consistently highlight ease of use and responsive customer support. SMARTe's 4.6/5 score is strong, but the review sample is small.
The recurring issues are accuracy inconsistency for niche accounts and CRM sync creating duplicates when not configured properly. The niche-account accuracy gap matters if you're selling into specialized verticals. The duplicate risk is a setup problem, not a product flaw - but it still burns time if your RevOps team doesn't catch it early. In our experience, CRM duplicate issues are almost always a configuration problem. Treat enrichment like a RevOps project, not a rep-side plugin (see sales pipeline challenges that show up when ops is under-resourced).
When Neither Tool Solves Your Real Problem
Look - 60% of sales teams say their data is outdated or inaccurate. If your actual bottleneck is contact data quality and freshness, not sending infrastructure or intelligence dashboards, you need a different kind of tool entirely.
Prospeo covers 300M+ professional profiles with 143M+ verified emails, 125M+ verified mobile numbers, and 98% email accuracy, all refreshed on a 7-day cycle. The industry average for data refresh is six weeks. That gap is where deliverability goes to die. It works as a standalone data layer that pairs with whatever sequencer you already run - Instantly, Smartlead, Lemlist, or any CRM. Pricing starts free with 75 emails per month, paid plans from roughly $39/mo, no annual contracts. At about $0.01 per email, it's a fraction of what either Clickback or SMARTe costs for the data piece alone (compare options in best outbound lead generation tools).
For teams that need both intelligence and sending, the play is pairing a data layer like Prospeo with a dedicated sequencer rather than trying to find one tool that does everything poorly.
Your real bottleneck isn't sending infrastructure or intelligence dashboards - it's stale data killing your deliverability. Prospeo's 7-day refresh cycle means your contacts are verified while competitors run on 6-week-old records. Pair it with any sequencer you already use: Instantly, Smartlead, Lemlist, or your CRM.
Fresh data, 98% accuracy, zero lock-in - start free with 75 emails.
FAQ
How do SMARTe credits work?
Each contact reveal costs credits. The free plan gives 10 credits per month. Pro runs $0.50/credit with selectable monthly bundles. Enterprise scales from $0.30/credit at 50K volume down to $0.20/credit at 1M. Buying signals and advanced filters are gated to higher tiers.
Can Clickback's list cleaning prevent all bounces?
No. The 287-point check removes spam traps and honeypots, but Trustpilot reviews still report deliverability issues. No cleaning tool guarantees zero bounces on purchased lists. The list source quality matters as much as the cleaning layer - garbage in, garbage out, regardless of how many checkpoints you run it through.
How do you prevent SMARTe enrichment from creating CRM duplicates?
Set up dedupe rules before turning on auto-enrichment. Use matching keys - domain plus name plus email - to catch overlaps. Run a sandbox test with a small batch first, map fields explicitly so enrichment updates existing records instead of creating new ones, and maintain a suppression list for contacts you've already disqualified. We've found that skipping the sandbox step is where most teams get burned.
What's a good alternative if I just need verified emails?
Prospeo delivers 98% email accuracy on a 7-day refresh cycle with a 92% API match rate, starting free at 75 emails per month. Pair it with whatever sequencer you already run. You don't need a full intelligence suite or a dedicated sending platform if the core problem is finding accurate contact data.
