WP Mail Bank: The #1 WordPress Mail SMTP Plugin
Are you 100% confident all your WordPress emails reach their destination?
It’s impossible to know what’s happening to your emails unless you have a well-designed and well-rounded SMTP plugin installed. Explained why and how down below.
Mail Bank is a FREE SMTP plugin that gives you every feature needed to guarantee fast and 100% confident email deliverability. This includes a list of features designed to test, log, and control your email deliverability, even over multiple WordPress installations and networks.
This plugin is developed by the in-house team of expert coders at Tech Banker. These are the people that will keep bringing you new and improved versions of Mail Bank every day of the week. The plugin updates automatically by default.
Mail Bank provides unique functionality by sending emails with customized Zend Framework.
An SMTP plugin will solve your email deliverability issues. But how?
We’re confident that you’ll love Mail Bank. The reason for this is that our plugin is one of the most reliable ways to fix email deliverability issues, as we understand what causes them. Let me explain.
There are many reasons why you might need an SMTP plugin. The most common reasons are poor authentication or your host blocking email delivery. The less common is bulk mail overload and being marked as a spammer due to it. This is why we have respective features for both situations. The email logger being the most important. Here are the reasons in detail:
Your host might have PHPmailer disabled. In this situation, your WP emails are plain and simple not delivered, as WordPress uses the PHPmailer by default to send mail.
Poor authentication due to PHPmailer. It’s a very complicated process to set up PHPmailer properly on a small WordPress site. In most cases trying to set up PHPmailer will result in your emails being either undelivered or being sent to the Spam folders. The cause for this is that PHPmailer doesn’t use any sort of authentication. The email service providers don’t know whether the emails they’re receiving are coming from a legitimate sender or not.
Bulk sending overload can happen even on SMTP. If you send hundreds of emails per day via a free SMTP provider you might be a victim of a lesser known problem. Sending this many emails puts a lot of load on the undedicated SMTP provider’s servers. Only a dedicated server such as Mailgun’s or SendGrid’s can handle large loads of outgoing emails daily. Install our plugin and see our email logger.
Where does WP Mail Bank come into this?
It reconfigures the wp_mail() function so you can set up your own outgoing email settings. You can use almost any SMTP service provider with our plugin.
This prevents the core issues with Sender Domain Policy and Spoofing, which are the primary causes of undelivered mail.
As said before, Mail Bank also supports the Mailgun and SendGrid APIs. This means that if you’re running a website with a larger userbase you’ll be able to improve your email deliverability drastically.
Over 50,000+ website owners have chosen Mail Bank as their email deliverability solution. Mail Bank fixes email deliverability issues quickly and painlessly.
Confident SMTP Email Deliverability
It gives you a large list of free email service providers to choose from. The most prominent and important being Gmail, Outlook, and Yahoo, which all support oAuth 2.0. But we know larger email senders require more serious solutions. So we’ve added support for the freemium Mailgun with 10,000 free emails per month and SendGrid APIs. Both of these APIs will drastically increase WP email deliverability.
Our email logger will give you information on all of your emails. This includes undelivered mail and the information required to debug undelivered mail. You’ll also be able to take action on each of the emails or use bulk actions to delete or resend them. You’ll never have to leave a portion of your users in the dark again with this feature.
Our customer support team will always help you with any arising issue. Note that Premium Edition Customers get priority support. If your emails become undelivered, and you can’t find a solution in our documentation, we ask you to please contact us at email@example.com. You may also give us suggestions and feedback on how well we’re doing for you. We care about our customers.
SMTP Security & Flexibility
Depending on your email service provider, you will be able to choose between oAuth 2.0, Cram-MD5, Simple Login, or Plain Authentication. oAuth 2.0 is the most secure and works with Gmail, Outlook365, Outlook, and Yahoo! Using oAuth 2.0 means you won’t have to store your username and password in a WordPress database. You’ll feel much safer with this. In addition to that, with oAuth 2.0 you won’t need to update your credentials if your email account’s password changes, it’s a set-and-forget feature.
You will be able to choose between TLS (Transport Layer Security) and SSL (Secure Sockets Layer) encryption. Both encryption methods are valid for use, but we recommend using TLS as it’s more secure.
Multisite & Teamwork Support
You’ll have support for WordPress multisite. You won’t have to install Mail Bank on all of the WordPress sites on your network. You’ll be able to take full control of all your networked sites from your main installation.
You’ll have the option to set roles and restrictions for other users. This is a perfect solution for working in teams. As if something goes wrong with your email service provider or settings you can be alerted by one of your users and no-one but you can touch the SMTP account’s settings.
Fast & In-Depth Email Setup
- Our «Email Setup» tab will guide you and let you create a working connection in seconds. But you’ll also have access to a large amount of more complicated settings as well. Just in case you need them.
- Download, install, and activate Mail Bank on your WordPress hosted site.
- Open the «Email Setup» tab.
- Enter your chosen name in the «From Name» tab, and enter a valid email in the «From Email» tab. Or choose not to override. A valid email will be provided by your email service provider or hosted on your domain, e.g. JohnDoe@[your domain].com or your Gmail address. Then, press «Next Step», and you’ll be taken to the SMTP account setup screen.
- Your email address should already be entered, and some default SMTP settings should appear. You can use these settings or set a different mailer type. The default settings for a Gmail SMTP account are: Mailer Type: Send Email via SMTP, Encryption: TLS Encryption, SMTP Host: SMTP.gmail.com SMTP Port: 587, Authentication: Login. You need to enter your Gmail credentials in this case. If you want to use oAuth 2.0, you’ll have to set it up with Google. Check whether you want to send a «Test Email», we recommend leaving this checked.
- Press «Next Step», and you’ll be taken to the «Test Email» screen. If anything’s wrong, it will tell you Email Status : Email Not Sent. Then, you need to look at the debugging information and recheck your SMTP settings. Note: You can’t use the «Login» option with Gmail SMTP accounts that have 2-factor authentication enabled, you have to use oAuth 2.0 with secured Gmail SMTP accounts.
- If all is well you’re done. If you’ve gotten stuck, there’s a button to ask for help on the test page, and there’s a «Help & Support» button on the tab list. Be sure to check your email logs frequently for any trouble.

Mail ends up in the Spam folder
To avoid being flagged as spam, you need to prove your email isn’t forged. On a custom domain, it’s up to you to set that up.
- Ensure you’re using the correct SMTP server with authentication – the correct SMTP server is the one defined by your email service’s SPF record.
- If you use a custom domain name for email, add an SPF record to your DNS zone file. The SPF is specific to your email provider, for example Google.
- If you use a custom domain name, add a DKIM record to your DNS zone file and upload your Domain Key (a digital signature) to, for example Google.
