class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Suppose a service provides:<\/p>\n<p><strong>100 checks\/day.<\/strong><\/p>\n<p>Used every day, that could theoretically provide approximately:<\/p>\n<p><strong>3,000 checks\/month.<\/strong><\/p>\n<p>That can be extremely useful for a freelancer or small agency.<\/p>\n<p>However, users should verify the provider&#8217;s current terms because free quotas can change.<\/p>\n<hr \/>\n<h2><span class=\"ez-toc-section\" id=\"Comment_3_%E2%80%9CDont_compare_tools_only_by_free_credits%E2%80%9D\"><\/span>Comment 3: &#8220;Don&#8217;t compare tools only by free credits.&#8221;<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A service offering 1,000 free checks isn&#8217;t automatically better than one offering 100.<\/p>\n<p>The 100-check service might include:<\/p>\n<ul>\n<li>SMTP verification<\/li>\n<li>Catch-all detection<\/li>\n<li>Disposable-email detection<\/li>\n<li>Risk scoring<\/li>\n<li>API access<\/li>\n<\/ul>\n<p>while the 1,000-check service might perform only basic syntax and domain checks.<\/p>\n<h3><span class=\"ez-toc-section\"

class=\"ez-toc-section-end\"><\/span><\/h1>\n<p>A catch-all domain may accept messages sent to many addresses regardless of whether the individual mailbox exists.<\/p>\n<p>Consequently, no external verification system can always guarantee that a particular catch-all address is genuinely active.<\/p>\n<p>A good validator should therefore distinguish:<\/p>\n<p><strong>Valid<\/strong><\/p>\n<p>from:<\/p>\n<p><strong>Risky \/ Catch-all \/ Unknown<\/strong><\/p>\n<p>rather than presenting everything as certain.<\/p>\n<hr \/>\n<h1><span class=\"ez-toc-section\" id=\"Comment_5_%E2%80%9CVerification_does_not_equal_engagement%E2%80%9D\"><\/span>Comment 5: &#8220;Verification does not equal engagement.&#8221;<span class=\"ez-toc-section-end\"><\/span><\/h1>\n<p>This is extremely important.<\/p>\n<p>Suppose a validator says:<\/p>\n<p><strong><a href=\"mailto:user@example.com\">user@example.com<\/a> = Valid<\/strong><\/p>\n<p>That doesn&#8217;t mean the person:<\/p>\n<ul>\n<li>Wants your emails<\/li>\n<li>Will open your email<\/li>\n<li>Will click your links<\/li>\n<li>Is still interested in your business<\/li>\n<li>Has given marketing permission<\/li>\n<\/ul>\n<p>Therefore:<\/p>\n<p><strong>Valid email \u2260 engaged subscriber.<\/strong><\/p>\n<p>Email verification should be combined with

adequate.<\/p>\n<p>If you have:<\/p>\n<p><strong>500,000 addresses<\/strong><\/p>\n<p>free verification becomes considerably less practical.<\/p>\n<p>The appropriate solution depends heavily on list

class=\"ez-toc-section-end\"><\/span><\/h1>\n<p>This may be the smartest use of free verification credits.<\/p>\n<p>Take the same sample list and test two or three services.<\/p>\n<p>Then
