Therefore, <b>we do not block the SMTP 25 port<\/b>. <\/p><p class=\"no-margin\">\n<\/p><p class=\"no-margin\">However, we have implemented<b> certain limitations <\/b>to prevent spam and ensure that our email service functions smoothly. One of the measures we&rsquo;ve taken is to <b>limit the number of emails sent per minute to 5 emails<\/b>. This way, we can prevent abuse of our email service, e.g., sending bulk or unsolicited emails, which can harm our clients and their reputation.<\/p><p class=\"no-margin\">\n<\/p><p class=\"no-margin\">Remember that <b>sending large volumes of emails in a short period of time<\/b> can cause email servers to <b>mark your messages as spam<\/b>, resulting in poor email deliverability rates.
