Introduction
Choosing a lead data provider is one of the highest-stakes calls in outbound: the wrong list wastes every downstream effort, yet every vendor claims the biggest, cleanest database.
This article is an independent, deliverability-first review of Apollo, written to help you decide whether it fits your team before you pay. It covers Apollo's data quality, real pricing, strengths and weaknesses, and how it compares to the alternatives. It's most useful for founders, SMB sales teams, and agencies weighing Apollo as their main prospecting tool.

Written by Nikita Bykadarov, CEO of Maildoso – a cold email infrastructure platform that powers 400,000+ mailboxes and 10M+ emails sent per day for over 6,000 companies. He has spent years building and running outbound sending infrastructure, which means his team sees, in real data, what happens after a list is bought: which sources bounce, which burn domains, and which actually reach the inbox. He reviews lead data tools through that deliverability-first lens.

How we review tools
Every review on this site follows the same process. We assess the product's public features and pricing, weigh them against hands-on familiarity with the outbound category, and cross-check them against aggregated third-party ratings from G2 and Trustpilot.
Our score reflects value for the buyer it's built for, not a one-size-fits-all ranking – a tool can earn a high rating for startups and still be the wrong call for an enterprise team. We call out weaknesses as plainly as strengths, we update reviews when pricing or features change, and we never accept payment to alter a rating or a verdict.

Our rating: ⭐⭐⭐⭐
Bottom line: The best value entry point in lead data, as long as you treat the built-in sending as a starting point, not your long-term infrastructure.

Ratings
Trustpilot: 3/5 (1,157 reviews)
G2: 4.7/5 (9,344 reviews)
The gap between the two scores is the story. G2 reviewers rate the product highly for value and features; Trustpilot is dragged down by billing disputes, account suspensions, and slow support on lower tiers. Read that as: the tool is good, the commercial experience can be rough if something goes wrong with your account.

Apollo in depth
Apollo is the tool most small teams reach for first: a 210M+ contact database and a built-in sequencer in one product, with a free plan that gives real database access. Its filtering is the standout – slice by role, industry, headcount, or tech, then push contacts straight into a sequence.
Two things hold it back. Data accuracy swings by segment, strong for common US roles and thin for niche titles and EU contacts, so verify before sending. And the credit system is the real cost: credits expire each cycle, phone numbers cost far more than emails, and overages add up. One caveat at scale — its built-in sending runs on shared infrastructure, so move serious volume to dedicated domains you control.

Pricing
Apollo has four tiers (annual pricing shown; monthly costs more):
Watch the credits, not just the plan price. Credits reset each cycle, phone lookups cost roughly 8x an email, and overage credits run about $0.20 each with a minimum purchase. Pricing as of June 2026 – confirm current figures on Apollo's site.
- Free – full database access, basic filters, limited mobile and export credits, ~250 emails/day under fair use.
- Basic – $49/user/month – advanced filters and unlimited sequences.
- Professional – $79/user/month – adds calling and unlimited email sending.
- Organization – $119/user/month (min. 3 users) – international calling and full API access.

A note on deliverability
Apollo helps you find leads and start sequences, but where your email sends from decides whether it lands. As you scale past light volume, move outreach to dedicated domains and warmed-up mailboxes you control. That's the gap Maildoso fills — ready-to-send infrastructure that keeps your data from bouncing into spam.
Most cold emails fail simply because they land in spam. People never even see your offer. Our SMTP and Google Workspace mailboxes are built specifically for outbound; this means your emails will finally be seen, and you’ll start getting more positive replies.
Boost your outbound with our infrastructure!
FAQ
- Q:Is Apollo worth it?A:For startups and small teams, yes – it's the best-value way to combine a contact database with outreach. Heavier or EU-focused teams usually outgrow it and add specialized tools.
- Q:How much does Apollo cost?A:There's a free plan, with paid tiers from $49/user/month (annual) up to $119/user/month. The bigger cost driver is the credit system, so check your real usage, not just the plan price.
- Q:Why is Apollo's Trustpilot score so low?A:Most negative reviews are about billing, renewals, and account suspensions rather than the product itself. The G2 score (4.7) reflects how reviewers rate the actual tool.
- Q:Is Apollo's data accurate?A:It's strong for common US roles and weaker for niche titles and European contacts. Verify any list before sending to protect your bounce rate.
- Q:Do I need to verify data before sending?A:Yes. Every database decays, and bounces hurt your reputation. Run any list through an email verification tool before the first send.
