New accounts start at much lower limits \u2014 sometimes as few as 10 to 100 per day \u2014 with Microsoft gradually increasing them as your sender credibility builds. Microsoft uses a dynamic, reputation-based system, and exact figures are not publicly disclosed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Microsoft 365 (Exchange Online) Accounts<\/h3>\n\n\n\n<p>All Microsoft 365 business plans \u2014 Business Basic, Standard, Premium, and Enterprise E1\/E3\/E5 \u2014 share the same Exchange Online limits, as confirmed in Microsoft&#8217;s official <a href=\"https:\/\/learn.microsoft.com\/en-us\/office365\/servicedescriptions\/exchange-online-service-description\/exchange-online-limits\" target=\"_blank\" rel=\"noreferrer noopener\">Exchange Online limits documentation<\/a>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>10,000 recipients per day per user<\/strong><\/li>\n\n\n\n<li><strong>500 recipients per message<\/strong> (configurable up to 1,000 by an admin)<\/li>\n\n\n\n<li><strong>30 messages per minute<\/strong><\/li>\n<\/ul>\n\n\n\n<p>There is no higher tier for Enterprise. The widely circulated &#8216;500,000 recipients per day&#8217; figure has no basis in any official Microsoft documentation and should be disregarded entirely. All Exchange Online plans enforce the same 10,000 recipients-per-day per-user ceiling.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What Is the TERRL? Microsoft&#8217;s New Tenant-Wide Limit (2025)<\/h3>\n\n\n\n<p>In 2025, Microsoft introduced a new layer of sending restriction called the <strong>Tenant External Recipient Rate Limit (TERRL)<\/strong>. Unlike the per-user limits above, TERRL caps your entire organization&#8217;s external sends per day \u2014 across all users combined.<\/p>\n\n\n\n<p>For trial organizations, the TERRL is set at 5,000 external recipients per day. For paid tenants, the limit scales with license count. Microsoft rolled out full TERRL enforcement through April 2026. If your team runs coordinated outreach campaigns, your tenant-level limit may be more restrictive than your individual user limit suggests. Read the full announcement on the <a href=\"https:\/\/techcommunity.microsoft.com\/blog\/exchange\/tenant-external-recipient-rate-limit\/4116480\" target=\"_blank\" rel=\"noreferrer noopener\">Microsoft Tech Community blog<\/a>, and check with your Microsoft 365 admin for your organization&#8217;s specific TERRL.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Gmail Sending Limits<\/h2>\n\n\n\n<p>Gmail&#8217;s limits are also tiered by account type, and the distinction between browser sends and SMTP sends matters more than most users realize.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How Many Emails Can Free Gmail Send Per Day?<\/h3>\n\n\n\n<p>Free Gmail accounts can send up to <strong>500 emails per day<\/strong> on a rolling 24-hour window. Each email can include up to 500 recipients when you send through a browser. The <a href=\"https:\/\/support.google.com\/mail\/answer\/22839\" target=\"_blank\" rel=\"noreferrer noopener\">Google support documentation<\/a> confirms these figures, which apply to the standard consumer Gmail account.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Free Gmail via SMTP: Recipient Limits Explained<\/h3>\n\n\n\n<p>When you send through SMTP (for example, via a third-party email client or script), the per-message recipient cap drops to <strong>100 recipients per message<\/strong>. This does not reduce your daily total \u2014 you can still send up to 500 emails per day. The 100-recipient cap applies per individual message only. This distinction matters for anyone configuring Gmail SMTP for outreach tools.

For free Gmail, this typically results in a 24-hour suspension of outbound sends. For Outlook.com, the block can last 24 to 48 hours. For Microsoft 365 and Workspace accounts, sends above the limit queue or bounce until the rolling 24-hour window resets.<\/p>\n\n\n\n<p>The more serious risk is not the temporary block \u2014 it is the damage to your <a href=\"https:\/\/www.warmy.io\/blog\/email-sender-reputation-score\" target=\"_blank\" rel=\"noreferrer noopener\">email sender reputation score<\/a>. Repeated overages signal spam-like behavior to ISPs, which can lead to permanent throttling, blacklisting, or account suspension even after the window resets.<\/p>\n\n\n\n<p>If you encounter an SMTP rate-limit error specifically, Warmy&#8217;s guide to the <a href=\"https:\/\/www.warmy.io\/blog\/smtp-error-421-4-7-26-email-rate-limit-exceeded-causes-fixes\" target=\"_blank\" rel=\"noreferrer noopener\">email rate limit exceeded error<\/a> walks through the exact causes and fixes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Send More Emails Without Getting Blocked<\/h2>\n\n\n\n<p>You have several options for increasing your safe daily send volume:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Upgrade your account.<\/strong> Moving from free Gmail to Google Workspace raises your daily limit from 500 to 2,000.

Free Gmail caps at <strong>500 emails per day<\/strong>. Google Workspace paid accounts allow up to <strong>2,000 per day<\/strong>. Outlook.com holds established free accounts to approximately <strong>300 unique recipients per day<\/strong>. All Microsoft 365 plans \u2014 including Enterprise \u2014 cap individual users at <strong>10,000 recipients per day<\/strong>, and since 2025 your organization&#8217;s total external sends are also subject to a tenant-wide TERRL limit.<\/p>\n\n\n\n<p>For small-scale senders, these limits are rarely a concern. For teams running active outreach, staying within them requires the right account type, proper domain warmup, and smart send scheduling.<\/p>\n\n\n\n<p><a href=\"https:\/\/app.warmy.io\/signup\" target=\"_blank\" rel=\"noreferrer noopener\">Start your free Warmy trial<\/a> and let Adeline AI build your sender reputation automatically \u2014 no credit card required.
