Allow Multiple Accounts vs Smooth SMTP

Allow multiple user accounts to be created, registered, and updated having the same email address. By default, WordPress only allows a specific email address to be used for a single user account. This plugin removes that restriction. The plugin’s settings page (accessed via Users -> Multiple Accounts or via the Settings link next to the plugin on the Manage Plugins page) provides the ability to allow only certain email addresses the ability to have multiple accounts (such as if you only want admins to have that ability; by default all email addresses can be used more than once). You may also specify a limit to the number of accounts an email address can have (by default there is no limit). The settings page also provides a table listing all user accounts that share email addresses (see screenshot). Compatible with Multisite and BuddyPress as well. Links: Plugin Homepage | Plugin Directory Page | Author Homepage Template Tags The plugin provides three optional template tags for use in your theme templates. Functions Returns a count of the number of users associated with the given email. Returns the users associated with the given email. Returns a boolean indicating if the given email is associated with more than one user account. Arguments $email (string) An email address. Filters The plugin exposes three filters for hooking. Typically, customizations utilizing these hooks would be put into your active theme’s functions.php file, or used by another plugin. c2c_count_multiple_accounts (filter) The ‘c2c_count_multiple_accounts’ hook allows you to use an alternative approach to safely invoke c2c_count_multiple_accounts() in such a way that if the plugin were deactivated or deleted, then your calls to the function won’t cause errors in your site. Arguments: same as for c2c_count_multiple_accounts() Example: Instead of: Do: c2c_get_users_by_email (filter) The ‘c2c_get_users_by_email’ hook allows you to use an alternative approach to safely invoke c2c_get_users_by_email() in such a way that if the plugin were deactivated or deleted, then your calls to the function won’t cause errors in your site. Arguments: same as for c2c_get_users_by_email() Example: Instead of: Do: c2c_has_multiple_accounts (filter) The ‘c2c_has_multiple_accounts’ hook allows you to use an alternative approach to safely invoke c2c_has_multiple_accounts() in such a way that if the plugin were deactivated or deleted, then your calls to the function won’t cause errors in your site.

Smooth SMTP gives you full control over how WordPress sends email. Configure SMTP as your primary sending method, set up a fallback for when things go wrong, get notified through your preferred channels, and keep a detailed log of every email your site sends. Primary Sending Method (SMTP) Configure any SMTP provider as your primary sending method. If you leave SMTP disabled, WordPress will continue using its default PHP mail — either way, all other features still work. Works with any SMTP provider: Gmail, SendGrid, Amazon SES, Mailgun, and more Configurable host, port, encryption (SSL/TLS), username, password, from email, and from name Secure credential storage using WordPress’s built-in options API Fallback Sending Method If the primary sending method fails, Smooth SMTP can automatically retry using a fallback. This works regardless of whether you’re using SMTP or WordPress’s default PHP mail as your primary. Fallback to WordPress Default (PHP mail) or a second SMTP server Full credential configuration for the fallback SMTP Logged separately so you can see exactly which method delivered each email Failure Alert Channels Get notified the moment an email fails — through the channels your team already uses. Slack, Discord Telegram (via Bot API — requires bot token and chat ID) WhatsApp (via CallMeBot webhook) SMS or any custom webhook endpoint Add multiple channels, enable/disable each independently Send Test Alert button per channel Alerts are throttled to at most one per 60 seconds to avoid flooding Email Summary Reports Receive a periodic HTML email summarising your site’s email activity.

SMTP credentials are stored in your WordPress database. No data is transmitted to external services except through the alert channels and SMTP servers you explicitly configure.
