This operation performs real-time server-to-server verification via SMTP communication. This operation allows the user to specify a timeout value, in milliseconds, for how long it can take to perform SMTP level checks. A minimum of 200 milliseconds is required to perform these checks. However, results are dependent on the network speed of an email&#8217;s host, which may require several seconds to verify. Average mail server response times are approximately between 2-3 seconds, but some slower mail servers may take 15 seconds or more to verify.<br \/>\n&nbsp;<\/article>\n<section aria-labelledby=\"EV3-ValidateEmailAddress-Recommended-URLEndpoints\">\n<h2 id=\"EV3-ValidateEmailAddress-Recommended-URLEndpoints\">URL Endpoints<\/h2>\n<ul class=\"is-style-no-bullets-indented-list\">\n<li><strong>JSON:<\/strong>&nbsp;\n<ul >\n<li><a href=\"https:\/\/trial.serviceobjects.com\/ev3\/web.svc\/json\/ValidateEmailAddress?EmailAddress={EMAILADDRESS}&amp;AllowCorrections={ALLOWCORRECTIONS}&amp;Timeout={TIMEOUT}&amp;LicenseKey={LICENSEKEY}\">https:\/\/trial.serviceobjects.com\/ev3\/web.svc\/json\/ValidateEmailAddress?EmailAddress={EMAILADDRESS}&amp;AllowCorrections={ALLOWCORRECTIONS}&amp;Timeout={TIMEOUT}&amp;LicenseKey={LICENSEKEY}<\/a><\/li>\n<\/ul>\n<\/li>\n<li><strong>XML:<\/strong>&nbsp;\n<ul>\n<li><a href=\"https:\/\/trial.serviceobjects.com\/ev3\/web.svc\/xml\/ValidateEmailAddress?EmailAddress={EMAILADDRESS}&amp;AllowCorrections={ALLOWCORRECTIONS}&amp;Timeout={TIMEOUT}&amp;LicenseKey={LICENSEKEY}\">https:\/\/trial.serviceobjects.com\/ev3\/web.svc\/xml\/ValidateEmailAddress?EmailAddress={EMAILADDRESS}&amp;AllowCorrections={ALLOWCORRECTIONS}&amp;Timeout={TIMEOUT}&amp;LicenseKey={LICENSEKEY}<\/a><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/section>\n<div style=\"display:flex; gap:16px; flex-wrap:wrap; margin:24px 0;\">\n<div style=\"border: 1px solid #d1d5db; border-radius: 8px; padding: 16px; max-width: 320px; background: #f9fafb; flex: 1;\">\n<h3 style=\"margin-top: 0; margin-bottom: 8px; font-size: 1.2em;\">Run This Request in Postman<\/h3>\n<p style=\"margin: 0; line-height: 1.4;\">Test with this email address:<br \/>\n<a style=\"font-weight: bold; color: #2563eb; text-decoration: none;\" href=\"https:\/\/www.postman.com\/service-objects-api\/service-objects\/example\/41579131-ca16ebfe-aec5-4733-ada4-a7c84fabbd6c\" target=\"_blank\" rel=\"noopener\"><br \/>\njsmith@serviceobjects.com<br \/>\n<\/a><\/p>\n<\/div>\n<div style=\"border: 1px solid #d1d5db; border-radius: 8px; padding: 16px; max-width: 320px; background: #f9fafb; flex: 1;\">\n<h3 style=\"margin-top: 0; margin-bottom: 8px; font-size: 1.2em;\">Check out the Integration Code in GitHub<br \/><\/h3>\n<p style=\"margin: 0; line-height: 1.4;\"><a style=\"font-weight: bold; color: #2563eb; text-decoration: none;\" href=\"https:\/\/github.com\/ServiceObjects\/email-validation-3\" target=\"_blank\" rel=\"noopener\"><br \/>\nGitHub<br \/>\n<\/a><\/p>\n<\/div>\n<\/div>\n<section aria-labelledby=\"EV3-ValidateEmailAddress-Recommended-ValidateEmailAddressInputs\">\n<h2 id=\"EV3-ValidateEmailAddress-Recommended-ValidateEmailAddressInputs\">ValidateEmailAddress Inputs<\/h2>\n<figure class=\"wp-block-table is-style-table-section\">\n<table class=\"has-black-color has-text-color\">\n<thead>\n<tr>\n<th>Name<\/th>\n<th>Type<\/th>\n<th>Description<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>EmailAddress<\/p>\n<\/td>\n<td>String<\/p>\n<\/td>\n<td>The email address you wish to validate.<\/td>\n<\/tr>\n<tr>\n<td>AllowCorrections<\/td>\n<td>String<\/td>\n<td>Accepts&nbsp;<strong>true<\/strong>&nbsp;or&nbsp;<strong>false<\/strong>.
