Email Lists of Training Buyers

Emailing a targeted list can be one of the most direct and cost-effective ways to reach potential clients, especially compared to paid ads or social media, where visibility is often throttled. With email, you’re landing directly in someone’s inbox—where decisions happen.

• Open Rate – % of delivered emails that were opened; shows subject line + sender effectiveness
• Click-Through Rate (CTR) – % of delivered emails that got at least one link click
• Conversion Rate – % of recipients who took the desired action (e.g., signed up, bought something)

In the U.S., including California, it is not illegal to email someone without their explicit permission—as long as you comply with the CAN-SPAM Act. That means:

• You must include a clear opt-out/unsubscribe mechanism.
• You must identify the message as an ad.
• You must include a valid physical mailing address.
• You must not use deceptive subject lines or headers.

California’s anti-spam law (CASL) is largely preempted by federal law (CAN-SPAM), so U.S. federal law governs most situations. Bottom line: “Opt-out” is legal in the U.S. (unlike the EU/Canada, which require prior opt-in).

Here are three common ways to build an email list that matches your targeting criteria: purchasing explicitly opted-in contacts, refining lists from data providers using filters, or scraping email addresses from websites and social media.

If you want to email people who have explicitly given permission and are likely to have high engagement rates, here are 4 lists you can purchase or rent that were compiled by training industry participants: magazines, conferences, and associations:

If you want a lower per-email cost and a larger list, you can filter a list from an email list provider, although expect lower engagement as other businesses have repeatedly emailed these people. Well-known email list providers include:

• Instantly.ai
• ZoomInfo.com
• Apollo.io
• Lusha.com

Scraped email lists are compiled by extracting addresses from websites, forums, directories, or social media profiles—without consent. While tempting for scale and low cost, they have the least engagement and highest rates spam complaints. Tools that offer web scraping for emails include:

• Instantly, Apollo.io, and Snov.io – Combine scraping-like features with contact enrichment
• Phantombuster, Scrapy, Octoparse, and ParseHub – General-purpose scrapers that can extract emails from websites and social media
