Key indicators such as time to conversion, conversion rate and customer lifetime value (<a href=\"https:\/\/mailrelay.com\/en\/glossary\/customer-lifetime-value-clv\/\" target=\"_blank\" rel=\"noreferrer noopener\">LTV<\/a>) should be measured. <\/p>\n\n<p class=\"wp-block-paragraph\">These metrics help you understand the effectiveness of your marketing and sales strategies and make adjustments when necessary.<\/p>\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n<p class=\"wp-block-paragraph\">SQLs are an essential component of the sales process. <\/p>\n\n<p class=\"wp-block-paragraph\">A digital marketing strategy that includes both email and SMS marketing can significantly increase the quantity and quality of SQLs. <\/p>\n\n<p class=\"wp-block-paragraph\">This leads to greater efficiency and effectiveness in the sales process.<\/p>\n\n<h2 class=\"wp-block-heading\">Related entries<\/h2>\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/erp\/\">ERP<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/likert-scale\/\">Likert Scale<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/scalability\/\">Scalability<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/esm\/\">ESM<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/email-marketing-strategy\/\">Email Marketing Strategy<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/exim\/\">Exim<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/email-extractor\/\">Email Extractor<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/facebook-ads\/\">Facebook Ads<\/a><\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"template":"","class_list":["post-76869","glossary","type-glossary","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 -
