HI @MouHouHassan-4457
Using Microsoft Outlook is a great option for business owners who regularly use Office 365. You can use your existing account to send emails to your subscribers from your WordPress website.
The best part about using Outlook is that it allows you to send a lot of emails at once. You can send up to 10,000 emails per minute, which is a much higher limit than other mailing services.
If you have a busy online store, then this will help you with sending receipts, tracking info, and abandoned cart emails to all your customers.
Another benefit that Microsoft Outlook provides is that you don’t have to use the default WordPress PHP mail() function to send emails.
There are many issues with the default mailing method. Many WordPress hosting services don’t have PHP mail properly configured, which leads to email deliverability problems.
Your emails can end up in the spam folder because email service providers like Gmail can’t detect where the email is coming from.
However, you can easily overcome this issue by using an SMTP service provider to send emails in WordPress through your Outlook account.
