Frequently Asked Questions
Common questions about Post SMTP – Complete Email Deliverability and SMTP Solution with Email Logs, Alerts, Backup SMTP & Mobile App
Once access is granted, Post commandeers the WordPress wp_mail() function to provide an incredibly stable mail sub-system.
There are many reasons why OAuth 2.0 is better than any password-based mechanism:
Post will never ask for your password, so your password can't be stolen
If you change your password regularly, you will never have to update Post's configuration
You have tighter control over the data Post has access to. For Google users, it can never access your Calendar or Docs or YouTube; for Yahoo users, it can never access your Flickr
If your WordPress site gets hacked, you can revoke Post's email access without impacting any other application or website that has access to your account
NEVER give out your Gmail, Microsoft or Yahoo password to a 3rd-party or 3rd-party program that you don't fully trust.
Can I use this plugin to send via Outlook, Microsoft 365, Gmail SMTP, Zoho, Yahoo, or SendGrid SMTP?
Yes! With the Post SMTP Plugin, you can configure any SMTP mailer account, including Brevo, Mailgun, and SendGrid on your WordPress site. Check out our detailed SMTP configuration documentation for all major SMTP service providers.
What is a Client ID?
To use OAuth, your website needs its own Client ID. The Client ID is used to control authentication and authorization and is tied to the specific URL of your website. If you manage several websites, you will need a different Client ID for each one.
How do I get a Microsoft Client ID? (For Hotmail/Live/Outlook.com users only!)
Go to Microsoft account Developer Center and select 'Create application'.
In the 'Application name' field, enter 'Post SMTP'. Select 'I accept.'
Select 'API Settings' from under 'Settings'.
In 'Redirect URL', enter the redirect URI given by Post (either from the wizard or from the manual configuration page). Select Save.
Select 'App Settings' from under 'Settings'.
Enter the Client ID and Client Secret displayed here into the Post's settings page.
