The last thing you want is for your emails not to reach their intended destination. While email marketers don&rsquo;t need to design for the algorithms, they have the spam traps to keep in mind.<\/p><p>Very few users check their spam folder. Instead, they just let whatever ends up in the spam folder get deleted after 30 days automatically. This means that if your emails get flagged as spam your emails will most likely go unseen and unread forever.<\/p><p>One of the solutions is to select a reliable email service provider (ESP). Instead of buying an email list (which you should never do), here are 11 top email deliverability tools that you can invest in.<\/p><p><span>\t\t\t<div class=\"csb-wrapper\" id=\"csb-spy\">\n\t\t\t\t<div class=\"csb-header\">Summary<\/div>\n\t\t\t\t<div class=\"scb-list\">\n\t\t\t\t\t<div class=\"csb-row-item -header\">\n\t\t\t\t\t\t<div class=\"csb-cell name-cell\"><span class=\"arrow-icon\"><\/span><span>Platform:<\/span><\/div>\n\t\t\t\t\t\t<div class=\"csb-cell best-for-cell\">Best For:<\/div>\n\t\t\t\t\t\t<div class=\"csb-cell price-cell\">Pricing:<\/div>\n\t\t\t\t\t\t<div class=\"csb-cell actions-cell\"><\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div data-tid=\"title_id_130100\" data-name=\"SMTP\" data-custom-link=\"\" href=\"https:\/\/influencermarketinghub.com\/email-marketing-software\/smtp\/\" class=\"csb-row-item \"  data-type=\"platform\" data-status=\"Normal (Invoice)\">\n\t\t\t\t\t<div class=\"csb-cell name-cell\"><span class=\"arrow-icon\"><\/span><div data-href=\"#csb-1\" class=\"csb-name-link\">SMTP<\/div><\/div>\n\t\t\t\t\t<div class=\"csb-cell best-for-cell \"><div class=\"csb-cell-inner\"> <span class=\"cell-icon icon-star\"><\/span><span class=\"cell-value\">Small to medium-sized businesses (SMBs), although also viable for larger companies <\/span><\/div><\/div>\n\t\t\t\t\t<div class=\"csb-cell price-cell \"><div class=\"csb-cell-inner\"><span class=\"cell-icon icon-wallet\"><\/span><span class=\"cell-value\">From $25<\/span><\/div><\/div>\n\t\t\t\t\t<div class=\"csb-cell actions-cell\"><div class=\"csb-cell-inner\"><div class=\"more-link\">View<\/div><\/div><\/div>\n\t\t\t\t<\/div>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"csb-footer\">\n\t\t\t\t\t<span class=\"csb-btn\" data-csb_more=\"more\"><span>Read more<\/span><span>Hide<\/span><\/span>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t\t<script>\n\t\t\t\t(($) => {\n\t\t\t\t\t$('.csb-row-item[data-tid]').on('click', function(e) {\n\t\t\t\t\t\tif (typeof gtag === 'function') {\n\t\t\t\t\t\t\tgtag('event', this.dataset.name, {\n\t\t\t\t\t\t\t\t'event_category': 'NEW LISTICLE WIDGET'\n\t\t\t\t\t\t\t})\n\t\t\t\t\t\t}\n\t\t\t\t\t\t\/\/ If a custom link is set on the row, navigate to it directly.\n\t\t\t\t\t\t\/\/ Otherwise fall back to clicking the heading anchor (keeps the\n\t\t\t\t\t\t\/\/ ni_get_link PPC tracked URL for laravel clients).\n\t\t\t\t\t\tif (this.dataset.customLink) {\n\t\t\t\t\t\t\twindow.open(this.dataset.customLink, '_blank');\n\t\t\t\t\t\t\treturn;\n\t\t\t\t\t\t}\n\t\t\t\t\t\t$(`#${this.dataset.tid} a`)[0]?.click();\n\t\t\t\t\t})\n\t\t\t\t})(jQuery)\n\t\t\t<\/script>\n<\/span><\/p><hr class=\"stag-divider stag-divider--dashed\"><h2><strong>What&rsquo;s Meant by Email Relay and Deliverability?<\/strong><\/h2><p>In a nutshell, email relay refers to the transmission of emails between servers.
