Be careful with mass internal\/external blasts.<\/li>\n<li><strong>Focus on engagement, not sheer volume<\/strong> \u2014 High volume with low engagement triggers policy breaches. Better to send fewer, more relevant emails.<\/li>\n<li><strong>Consider alternative channels<\/strong> \u2014 Email alone may not suffice. Use multi-channel outreach (social, SMS, in-app), especially as bulk email becomes harder to scale.<\/li>\n<li><strong>Monitor metrics and provider dashboards<\/strong> \u2014 Use tools (e.g., Google Postmaster, Microsoft monitoring) to check your reputation, delivery, bounce\/compliant rates.<\/li>\n<li><strong>Use proper infrastructure for bulk sends<\/strong> \u2014 If you send high volume, consider using a dedicated ESP or email platform built for bulk mailing rather than standard mail system (especially Exchange Online).<\/li>\n<\/ol>\n<hr \/>\n<h2><span class=\"ez-toc-section\" id=\"_Final_Thoughts\"><\/span>\u00a0Final Thoughts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The tightening of bulk-send policies by major platforms is <strong>not just a compliance update<\/strong> \u2014 it\u2019s a paradigm shift in how outreach must be done.
