Clodura.AI vs Apollo.io: Which One Actually Delivers?
Your SDR team exported 2,000 contacts last week. 350 bounced on the first send. Now you're weighing Clodura.AI vs Apollo.io, trying to figure out which one won't torch your sender reputation.
Here's the thing: we've tested both platforms extensively, and the answer isn't as clean as either vendor's marketing page suggests. Let's break it down.
30-Second Verdict
Pick Apollo.io if you want the largest all-in-one ecosystem - 73 integrations, built-in sequencing, a dialer - and you can stomach per-seat costs plus credit budgets.
Pick Clodura.AI for unlimited users, credit-based pricing, and waterfall enrichment pulling from 50+ data providers.
Skip both if bounce rates are the real problem. Prospeo delivers 98% email accuracy on a 7-day refresh cycle, starting free.
Ratings at a Glance
| Metric | Apollo.io | Clodura.AI |
|---|---|---|
| G2 Rating | 4.7/5 (9,512 reviews) | 4.5/5 (301 reviews) |
| TrustRadius Score | 8.5/10 | 9.6/10 (4 ratings) |
| Ease of Use (G2) | 9.0 | 8.9 |
| Quality of Support | 8.8 | 9.1 |
Apollo wins on review volume - 30x more G2 reviews gives you a far more stable signal. Clodura's TrustRadius score looks impressive at 9.6, but four ratings is directional, not definitive. The more telling number: on G2, "Inaccurate Data" appears as a con in 503 Apollo reviews versus just 15 for Clodura. That's a 33x gap, and it tracks with the email bounce rate complaints we'll get into below.
Pricing Compared
Apollo.io Plans
| Plan | Annual | Monthly | Key Limits |
|---|---|---|---|
| Free | $0 | $0 | 5 mobile credits/mo, 10 export credits/mo |
| Basic | $49/user/mo | $59/user/mo | 5,000 data credits/yr |
| Professional | $79/user/mo | $99/user/mo | 10,000 data credits/yr, US dialer |
| Organization | $119/user/mo | $149/user/mo | Min 3 seats, 15,000 data credits/yr |
Credits don't roll over. Overages cost $0.20/credit with a 250-credit minimum, and you can't reduce seats mid-term. A 10-seat Professional plan on annual billing runs $9,480/year before overages. Apollo's free tier is functional but aggressive - expect constant upgrade prompts and feature gates pushing you toward paid plans.
Clodura.AI Plans
| Plan | Price | Credits/mo |
|---|---|---|
| Free Forever | $0 | 100 (unlimited users) |
| Max 5K | $99/mo ($90 annual) | 5,000 |
| Max 10K | $194/mo ($175 annual) | 10,000 |
| Max 20K | $378/mo ($340 annual) | 20,000 |
Clodura charges 1 credit per verified email and 10 per phone number. The unlimited-users model means a 15-person team pays the same as a 3-person team, and credits roll over for two months. Worth noting: TrustRadius lists a legacy per-seat model at $49-$99/user/mo, so confirm current pricing directly with Clodura before signing.
Tired of comparing pricing tiers when the real issue is 15-25% bounce rates? Prospeo's 5-step verification and 7-day data refresh deliver 98% email accuracy - no third-party data providers, no stale records. At ~$0.01/email, a 10-person team spends less than either Apollo or Clodura.
Stop comparing bad data sources. Start with accurate ones.
Data Accuracy and Deliverability
This is where the comparison gets uncomfortable for Apollo.
A popular Apollo review breakdown pegs typical exports at 15-25% bounce rates with overall accuracy around 65%, and Reddit threads echo the same theme: lists that look fine in-app fall apart once you actually send. The r/coldemail community's recurring concern is the overused data problem - Apollo's massive user base means the same prospects get hammered by everyone using the platform, which tanks reply rates even when the emails are valid. If you're troubleshooting this end-to-end, use an email deliverability guide to isolate whether the issue is list quality, authentication, or sending behavior.
Users on r/sales have also reported mobile numbers taking up to 10 minutes to load, a UX drag that compounds on large lists. Apollo also had two data breaches (2018 and 2021) exposing 130M+ records, which is worth factoring into your security evaluation.
Clodura fares better: 28 bounces out of 1,529 verified leads - roughly 98% deliverability. The caveat matters, though. That test only exported verified emails, not guessed ones. In our testing, we've found that exporting only verified records from any platform dramatically changes the deliverability story. The real question is what percentage of your target list comes back verified in the first place.
Features Side by Side
| Feature | Apollo.io | Clodura.AI |
|---|---|---|
| Database Size | 275M+ contacts | 600M+ claimed |
| Integrations | 73 | Fewer native integrations |
| Sequences | Yes (2 on free, unlimited Pro+) | Yes |
| Dialer | US only (Pro); intl (Org) | Available via CallPilot |
| Enrichment | Built-in database | Waterfall (50+ providers) |
| Intent Data | Bombora + proprietary | Bombora |
Apollo's integration ecosystem is its real moat. Seventy-three integrations versus a smaller native set isn't close - if your stack is integration-heavy, Apollo is usually the cleaner fit.
Clodura's waterfall enrichment is the counter-punch: cross-referencing 50+ data providers and 20+ phone number providers is designed to improve coverage on harder-to-find contacts, especially outside the US where Apollo's data thins out considerably.
Look, most teams agonize over Apollo vs. Clodura when their actual problem is data quality, not workflow features. If your bounce rate sits above 5%, you need better data before you need better sequencing.
Who Should Pick Which
Apollo makes sense for teams under 5 seats that live inside a complex integration stack and primarily target US prospects. The sequencing and dialer are genuinely good - we won't pretend otherwise. If you're evaluating the broader category, compare options across SDR tools and outbound lead generation tools before committing.
Clodura wins on economics for larger teams where per-seat pricing would bleed the budget dry. A 15-person team on Apollo Professional pays $14,220/year; on Clodura Max 10K, that same team pays $2,100/year for shared credits. That's not a rounding error.
We've seen teams pick Apollo for the workflow and Clodura for the data, then wonder why they're paying for two tools that overlap on 80% of functionality. The real question is which gap hurts more - workflow or accuracy.
When Neither Fits
If bounce rates drove you to this comparison in the first place, the problem isn't which of these two platforms you pick. It's the data layer underneath.
Prospeo covers 300M+ professional profiles with 98% verified email accuracy and 125M+ verified mobile numbers. Its proprietary email-finding infrastructure doesn't rely on third-party providers - every record goes through a 5-step verification process with catch-all handling, spam-trap removal, and honeypot filtering. Data refreshes every 7 days, compared to the 6-week industry average.
Self-serve pricing starts free at 75 emails/month plus 100 Chrome extension credits/month, with paid plans at roughly $0.01 per email. Teams switching from Apollo report 35% more meetings booked after cleaning up their data source. If your domain reputation has already taken damage from bad data, switching databases matters more than switching sequencers.

Teams switching from Apollo report 35% more meetings booked after fixing their data layer. Prospeo covers 300M+ profiles with 125M+ verified mobiles and 98% email accuracy - refreshed weekly, not monthly. No per-seat pricing, no annual contracts.
Fix the data first. The meetings follow.
FAQ
Is Clodura.AI really free?
Yes - a Free Forever plan with 100 credits/month and unlimited users. Credits roll over for two months. Paid plans start at $99/month for 5,000 credits, making it accessible for small teams testing the platform before committing.
Does Apollo.io charge per seat?
Yes. $49-$149/user/month depending on tier and billing term, plus usage-based credits that don't roll over. You can't reduce seats mid-contract, so a 10-person team on Professional pays $9,480/year minimum.
Which tool has better email accuracy?
Clodura's verified exports show roughly 98% deliverability in independent tests, while Apollo commonly sees 15-25% bounce rates on raw exports. For teams where accuracy is the top priority, Prospeo's 98% verified email accuracy on a 7-day refresh cycle outperforms both - with a free tier of 75 emails/month to test before committing.
Can I use Clodura and Apollo together?
You can, but most teams find it redundant. Both cover similar contact databases. A more practical stack is pairing one sequencing tool with a dedicated data provider for cleaner separation of workflow and data quality.
