G-Lock EasyMail7 vs Prospeo: Different Tools, Different Jobs
If you're comparing G-Lock EasyMail7 vs Prospeo, you're probably looking at two completely different needs. EasyMail7 is a Windows client-server app for running email campaigns in-house. Prospeo is a B2B data platform that finds verified contact data. Comparing them head-to-head doesn't make much sense - but understanding which one you actually need does.
30-Second Verdict
Here's the thing: these tools don't compete. EasyMail7 sends campaigns to lists you already have. Prospeo finds verified emails and phone numbers so you have someone to contact in the first place.
If you need to send bulk campaigns in-house with a one-time license fee, EasyMail7 is your tool. If you need accurate B2B contact data, Prospeo is your tool. Need both? Use both.
Skip both if you want a cloud-based all-in-one - look at HubSpot or Apollo's outreach suite instead.
What Each Tool Does
G-Lock EasyMail7
EasyMail7 is a client-server email marketing solution for Windows. It doesn't send email by itself - it's a front-end to third-party SMTP/delivery services like Amazon SES, SendGrid, or Mailgun. You bring your own list, design campaigns, schedule sends, and manage bounces and unsubscribes from a desktop client while keeping your data in-house.
The import engine is genuinely fast: G-Lock claims it can import 1 million email addresses in 43 seconds.
Pricing is the main draw. A one-time license starts at $159 (Personal), $259 (Business), up to $1,569 (Enterprise, 30 users). No monthly software fees, though you'll still pay your SMTP provider - Amazon SES runs about $1 per 10,000 messages. Licenses are valid for one year of updates and support. After that, renewal runs 50% of the regular price if you pay within the first month of expiration, dropping to 30% in months 13-14, 10% in months 14-15, and nothing after 15 months.
Capterra gives it 4.8/5 from 33 reviews, with Customer Service scoring a perfect 5.0. G2 rates it 5.0/5, though from only 3 reviews - so take that with a grain of salt.
The tradeoffs? One G2 reviewer called it "not for novices" used to structured platforms like Mailchimp, and multiple reviews flag that reporting and statistics are minimal. The interface can feel dated, which is the cost of a non-cloud architecture.
Prospeo
Prospeo sits on the opposite end of the email workflow. Instead of sending campaigns, it finds the people you'd send them to.
The platform covers 300M+ professional profiles, 143M+ verified emails, and 125M+ verified mobile numbers - all refreshed on a 7-day cycle, which is roughly 6x faster than the industry-average 6-week refresh. Over 15,000 companies use it, and the Chrome extension has 40,000+ users for one-click prospecting from any website or inside CRMs. Email accuracy sits at 98%, backed by a proprietary 5-step verification process with catch-all handling and spam-trap removal (see our guide to spam trap removal).
Pricing is credit-based, starting free with 75 emails and 100 Chrome extension credits per month, then scaling at roughly $0.01 per email. No contracts, no sales calls required.
EasyMail7 needs a list before it can send a single email. Prospeo gives you 300M+ profiles with 98% verified email accuracy and 125M+ mobile numbers - all refreshed every 7 days. Build your list first, then send it anywhere.

Different cost structures for different jobs. EasyMail7's one-time fee excludes SMTP sending costs (about $10 per 100,000 emails through Amazon SES). Prospeo's credit model is pay-as-you-go for data, not for sending messages. Don't try to compare them dollar-for-dollar.
Which One Do You Need?
You already have a contact list and need to send campaigns cheaply. EasyMail7 makes sense. The one-time license plus Amazon SES is hard to beat for high-volume senders who don't mind a Windows-only workflow (if you're evaluating other senders, see AI bulk email senders).
You need to find prospect emails and phone numbers before you can do anything. You can't send a campaign to people you haven't identified yet. Prospeo's 30+ search filters - including buyer intent powered by Bombora, technographics, and job-change signals - let you pull verified contacts, then send through whatever tool you prefer (more on firmographic and technographic data).
You need both finding and sending. Pair Prospeo for data with EasyMail7 or a modern outreach tool like Instantly or Lemlist for execution. In our experience, and echoed across Reddit threads about email-finding tools, the buying criteria people actually care about are accuracy, freshness, and global coverage - none of which apply to a campaign sender like EasyMail7. They're genuinely complementary (compare options in our roundup of outbound lead generation tools).
Can You Use Both Together?
Absolutely. We've seen teams build a verified contact list using intent data, technographic filters, or job-change signals in Prospeo, then export via CSV or push directly to a CRM through native integrations with Salesforce and HubSpot (see our guide on how to connect outreach tool to CRM). From there, import that clean list into EasyMail7 or any ESP for campaign execution.
One tool answers "who do I contact?" The other answers "how do I reach them at scale?" When you're weighing G-Lock EasyMail7 vs Prospeo, the real answer for most outbound teams is that they solve sequential steps in the same pipeline (and if bounces are a concern, review email bounce rate benchmarks and fixes).
Pairing a campaign sender with bad data is how domains get burned. Prospeo's 5-step verification and 7-day refresh cycle keep bounce rates under 4% - just ask the teams that tripled their pipeline after switching.
Feed EasyMail7 clean data at $0.01 per verified email.
FAQ
Is G-Lock EasyMail7 free?
No. One-time licenses start at $159 (Personal). You'll also need an SMTP service like Amazon SES, which costs about $1 per 10,000 emails. A 14-day free trial is available before purchasing.
Can Prospeo send email campaigns?
No. Prospeo finds and verifies B2B contact data - 143M+ emails at 98% accuracy. For sending, pair it with an outreach platform like Instantly or Lemlist, both of which integrate natively.
What's the best tool for outbound prospecting?
For finding contacts, Prospeo leads with 300M+ profiles, 98% email accuracy, and 125M+ verified mobile numbers on a 7-day refresh cycle. EasyMail7 sends campaigns but doesn't discover prospects - you'd need a data tool first.
Can I replace both tools with one platform?
Cloud platforms like Apollo or HubSpot bundle prospecting and sending, but they trade specialization for convenience. Dedicated tools typically outperform all-in-ones - Prospeo's 98% email accuracy beats Apollo's 79%, and EasyMail7's one-time pricing beats any monthly ESP for high-volume senders.
