# Apollo.io

> A B2B contact database with built-in email sequences and a dialer, priced per user with a shared credit pool.

Apollo combines a large B2B contact and company database (the vendor claims 240M contacts and 30M companies) with prospecting tools: search filters, email and phone reveals, enrichment, email sequences, a dialer on higher plans, and CRM sync. Paid plans are priced per user, and data actions draw on a credit pool shared by the team. Credits reset each billing cycle and do not roll over. A free plan exists for light use.

## Capabilities

| Capability | Fit | Plans | Limitations |
|---|---|---|---|
| Find verified contact data (emails, phones) (`contact-data`) | native | all | Credits limit how many reveals you can do; Free plan is very limited; Data accuracy not independently verified |
| Research prospects and accounts (`prospect-research`) | strong | all | AI research uses credits |
| Send sales email sequences (`email-sequences`) | native | basic, professional, custom | Free plan connects Gmail only; Deliverability depends on your own domain setup |
| Manage contacts and customer records (`crm-contacts`) | partial | all | Not a full replacement for a dedicated CRM |
| Track a sales pipeline (`sales-pipeline`) | partial | all | Basic deal tracking and forecasting compared with a dedicated CRM |
| Automate simple app-to-app workflows (`workflow-automation`) | partial | professional, custom | Scoped to Apollo's own data and actions |

## Why people pay for it

- One affordable tool that both finds contacts and sends sequences.
- Large searchable database with filters for title, industry, size and technology.
- Email and phone reveals plus CRM enrichment for Salesforce and HubSpot.
- Dialer and call recording on higher plans.
- Cheaper entry point than enterprise data vendors.

## Reasons to keep paying

- A maintained, verified B2B contact database; an AI assistant cannot reliably produce real, current business emails and phone numbers.
- Database search plus sequencing in one place, so a small team avoids buying two products.
- Ongoing enrichment of CRM records as people change jobs.

## Risks

- **compliance** (high): Cold email to purchased or looked-up contacts must follow CAN-SPAM, GDPR/PECR and CASL; GDPR applies to EU/UK data subjects regardless of the sender's location.
- **reliability** (medium): Bounce rates rise if data is stale; verify before large sends to protect domain reputation.
- **vendor_lock_in** (low): Credits do not roll over, so unused paid capacity is lost each cycle.

Data portability: moderate — Your own contacts, lists and sequence data can be exported, and records sync to CRMs. Export volume is limited by plan, and revealed data used outside Apollo is subject to Apollo's terms.
