Pricing comparison
Both platforms are enterprise-priced, but Warmly offers a free tier that ZoomInfo doesn't match.
| Plan | Warmly | ZoomInfo |
|---|---|---|
| Free | $0/mo (500 visitors, 10 Bombora signals/week) | Community Edition (requires data sharing) |
| Entry paid | TAM: ~$1,250/mo ($15,000/yr) | Professional: ~$1,250/mo ($14,995/yr) |
| Mid-tier | Inbound: ~$2,500/mo ($30,000/yr) | Advanced: ~$2,083/mo ($24,995/yr) |
| Top tier | Full GTM: Custom pricing | Elite: ~$3,333/mo ($39,995/yr) |
| Contract | Annual | Annual only, per-seat, 3-seat minimum |
Entry-level pricing looks similar (~$1,250/mo), but ZoomInfo's per-seat model means a team of 3 could pay $45,000+/year on the Professional plan alone. Warmly's pricing is per-account, not per-seat. Both require annual commitments on paid plans.
The biggest difference: Warmly's free plan gives small teams a way to start without a sales call. ZoomInfo has no equivalent.

Your sales team needs direct-dial phone numbers for 10,000+ prospects in the US. Which platform is the better fit?
Right! ZoomInfo's massive database with direct-dial phone numbers is built for large-scale outbound prospecting. Warmly doesn't provide phone numbers or a prospecting database — it identifies visitors on your own website.
ZoomInfo is the answer here. Its 260M+ contact database includes direct-dial phone numbers. Warmly focuses on identifying anonymous website visitors, not building outbound prospect lists with phone data.
Who should choose Warmly?
- Teams that want to convert existing website traffic into pipeline
- Companies that need real-time visitor engagement (AI chatbot, live routing)
- Small teams that want a free starting point
- Marketing teams that want to see which companies visit their site
- Teams already using HubSpot or Salesforce
Who should choose ZoomInfo?
- Outbound sales teams that need a large prospecting database
- Teams that rely on direct-dial phone numbers for cold calling
- Enterprise organizations that need org charts and technographic data
- Companies with budget for $15K+/year per seat
- Teams that need 50+ CRM and tool integrations
You run a startup getting 2,000 website visitors per month but have no sales team doing outbound. You want to know which companies are visiting and engage them automatically. Which tool fits?
Correct! Warmly is purpose-built for this scenario. It de-anonymizes your visitors, shows you which companies are browsing, and engages them in real time with an AI chatbot. You can even start free with 500 visitors/month.
Warmly is the right choice. It identifies anonymous website visitors and engages them automatically. ZoomInfo is an outbound prospecting database — it doesn't track or engage your website visitors as a core feature.
A simpler alternative: MentionAgent
Both Warmly and ZoomInfo are enterprise tools with enterprise pricing. Warmly requires meaningful website traffic to be useful. ZoomInfo requires a large budget and a team to work the data. Both assume you have the infrastructure to turn intelligence into outreach.
MentionAgent takes a different approach entirely. It automates the full outreach workflow — finding relevant prospects in your niche, looking up contacts, writing personalized emails, and sending follow-ups. No visitor traffic required. No massive database to search through. No enterprise contract.
- Price: $99/mo. Not $15,000/year.
- Setup time: Minutes, not weeks
- Manual work: Approve emails. That's it.
- No per-seat pricing: Flat monthly rate, cancel anytime
You're a solo founder without enterprise budget. You need to generate leads but can't afford $15K+/year for sales intelligence. Which option works?
Correct! Warmly's free plan only identifies 500 visitors (you need traffic first), and ZoomInfo's Community Edition requires sharing your own contact data. MentionAgent ($99/mo) handles the entire outreach process — finding prospects, writing emails, and following up — without enterprise contracts.
Warmly's free plan is limited to 500 visitor identifications (and you need website traffic to begin with). ZoomInfo's Community Edition requires you to share your own contacts. MentionAgent ($99/mo) automates prospecting and outreach end-to-end, no enterprise budget needed.
