This usage guide covers the email options available with your WPMU DEV hosting account. If you haven’t set up a WPMU DEV hosting account yet, visit the hosting page where you can explore the features, see pricing packages, and start a free trial.

The types of email available with a WPMU DEV hosting account are:

  • Transactional Email – These are emails WordPress sends regarding the administration and maintenance of your WordPress site.
  • Email Accounts – Members whose sites we host can create up to 10 free email accounts for each site to send and receive domain emails using any email client or cloud-based email service.
  • Email Forwarding – Forwarding is a simple way to create an email address that includes your domain name, without having to incur additional costs.
  • SMTP – Use any email service with valid SMTP credentials and our Branda plugin to send WordPress transactional emails from another email address that you own.

Each form of email has its own strengths and limitations (see below). Use this guide to determine which works best for your site or network.

10.1 Email Policies and Limitations

Copy chapter anchor to clipboard

The email options described above are available on all WPMU DEV hosted sites at no additional cost, because we recognize that email is fundamental to growing a site. Yet, we still need to manage the resources this service consumes, so some limitations are appropriate.

Transactional Email Policies

These are emails WordPress sends regarding the administration and maintenance of your WordPress site. Examples include WordPress updates, new user registrations and user comments.

In order to protect our members’ domain reputations and to keep their emails from winding up in spam inboxes, the From address on these transactional emails is [email protected]. All WPMU DEV sites are preconfigured to handle transactional emails in this way, and no configuration is required.

We do not allow sending non-transactional emails from [email protected]. This restriction applies to email subscriptions, newsletters, marketing, or mass email. These types of emails should be sent from an email address you own.

If you wish to change the From address on noreply emails to an address you own, see the Using SMTP To Send Emails chapter below.

Transactional Email Limits

The number of transactional emails sent per day and month for each site is also limited, as shown below. These limits only apply if you are using our default [email protected] address. They do not apply if you’re using an email address you own through a third-party mail service.






Daily Limit





Monthly Limit





If your site exceeds these limits, we will temporarily block email sending and notify you if you exceed your monthly quota. If your site needs to regularly send more emails than our quota allows, please upgrade your plan or configure WordPress to use SMTP or another transactional email service like Mailgun.

You can view the number of emails your site has sent during the past 30 days in the Site Email Stats area of the Email Dashboard.

email site stats


Note that if you use another email service provider with a created address, including using SMTP with Branda, those emails cannot be logged and you will not see any stats here.

Email Account Limitations

Members whose sites we host can create up to 10 email accounts for each site to send and receive domain emails using any email client or cloud-base email service.

There is no additional charge for these email accounts, and the only limitations are:

  • Email accounts are available only for sites we host.
  • Email addresses can only be created for primary domains (not subdomains).
  • Each hosted site can create ten domain email addresses. If more addresses are needed, we recommend using a dedicated email service, such as G Suite or Zoho.
  • Members cannot create domain email addresses and email forwarding addresses using our forwarding tool for the same site.
  • Storage

    Each inbox is limited to 100MB of total storage with file attachments limited to 15MB. Additional storage cannot be purchased. Members can avoid excessive storage use by configuring their email clients to delete emails from the server as soon as possible after they are pulled into the client.

Email Forwarding Limitations

WPMU DEV members can create as many forwarding addresses as they wish, but email forwarding does have its limitations:

  • WPMU DEV can only forward emails for domains we host.
  • Email forwarding only allows you to receive emails sent to an address you create. In order to send emails with your domain in the address, use the Email Account SMTP options discussed in this guide.
  • Email forwarding and domain email cannot be employed at the same time for a single domain. Email can only be sent from one location, as determined by the domain’s MX records. Email forwarding requires different MX records than standard email, so the two cannot co-exist on a single site.

10.2 Email Accounts

Copy chapter anchor to clipboard

Members whose sites we host can create up to 10 email accounts for each site to send and receive domain emails using any email client or cloud-base email service.

The following guidance covers creating email accounts, adding new MX records to the DNS files and connecting email accounts to some common email services.

POP and SMTP Only

Please note that WPMU DEV email accounts are POP and SMTP email only. We cannot support IMAP email accounts. However, if your email provider supports IMAP, as both Outlook and Gmail do, then you should consider using our email forwarding service, which can forward IMAP emails to the inbox of your choice.

10.2.1 Creating an Email Account

Link to chapter 2

WPMU DEV email is site-specific. In your Hub, click the site for which you wish to configure email. Click the Hosting tab, then click the Emails tab.

Locating email management tools

Once there, click the Email Accounts option to open the Email Account creation and management tool.

Email accounts tab

If you have not created an email address click the Add email account button to get started.

Add email account

This will open the Add email account module. Input the address you would like to create. This should be something like [email protected].


Copy the strong password provided or create your own password, and click the Add button to create your new email address.

This will generate your account and add all the information you need to connect to your email application.

10.2.2 Email Aliases

Link to chapter 2

Email aliases are a simple way to receive email sent from multiple addresses at the same email account. You need to have already set up at least one email account in your Hub before you can create aliases.

For example, if you have already set up an email account for [email protected], you could create various aliases to use like [email protected], [email protected], [email protected], etc, and receive mail from all of those at [email protected]

To get started, click the Add Alias button in the Active Email Aliases section just under Active Email Accounts.

Create email alias in Hub 2.0

In the modal window that pops open, enter the alias name you wish to use in the Alias field. Then select the actual email account this alias should send to in the Email dropdown, and click Add.

Email alias options in Hub 2.0

Check the Catch All ? checkbox if you want this new alias address to catch all emails sent to any address at your domain that does yet exist.

In other words, if you have an email account set up for [email protected], any email sent to that address will arrive in that account’s inbox. But if someone sends an email to [email protected], and there is no account set up for that address, it would arrive in that same inbox as well if it set as a catchall address.

Email catchall alias option in Hub 2.0

You’ll then see your new alias appear in the Active Email Aliases section, and can now use that alias anywhere you like. Any email sent to that address will be received at the actual email account associated with it.

Active email aliases in Hub 2.0

To delete an existing alias, click the Delete button in the alias row, then click the Delete button in the confirmation modal that pops open.

Delete an email alias in Hub 2.0

10.2.3 Updating DNS MX Records

Link to chapter 2

In order to send and receive emails from your new email address, you will need to add the MX info to your DNS record. For information on adding and managing your DNS records in Hub 2.0 visit the DNS records manager documentation.

MX Records are Mail Exchange Record use specify the mail server responsible for accepting email messages on behalf of a domain name.

When adding the MX record to your DNS records:

  • Set the Type to MX
  • Set Hostname to @ – this points the record to the root name
    If your DNS manager does not accept @ in the Hostname field and requires the domain name, be sure to include the period at the end of the name; without it, email will not work.
  • Value for MX records managed by WPMU DEV is
    Here, the period at the end is optional; mail will work whether you include it or not.
  • For DNS records on WPMU DEV the Priority should be set to 1
  • TTL (Time to Live) defaults to 14400 seconds

G-Suite & Google Domains

If you are a G-Suite user and/or are setting up MX records for a domain hosted by Google Domains, you’ll want to configure DKIM and SPF records before configuring DMARC. According to Google, DKIM and SPF should be authenticating messages for at least 48 hours before turning on DMARC.

If you are having trouble with the DKIM and/or DMARC entries after 48 hours, you can try editing those 2 entries so they do not include the domain name in them as provided in your Hub. Edit them so they look like the below example:

Edit DNS entries at Google Domains

If you get an error in your Hub saying that the SPF record is missing, you can try deleting that record and re-adding it as a TXT record instead.

10.3 Connecting Email Accounts

Copy chapter anchor to clipboard

This section covers how to connect your WPMU DEV Hosted Email Accounts to some of the more popular mail client applications for sending and receiving emails.

If you do not see your email application on the list or are having trouble connecting your Email Account, contact live support for 24/7 Hosting, DNS, and Email assistance.


Regardless of the email client you use, please be sure to configure it to remove email from the server once it is fetched by the client. Each inbox is limited to 100MB of total storage, so if emails are not removed once they are downloaded, that can fill up very fast. Each email client will have an option for that, but it may differ from one client to another. Check the configuration guides below for examples.

10.3.1 Apple Mail

10.4 Email Forwarding

Copy chapter anchor to clipboard

Email forwarding is a simple way to use an existing email account, such as Gmail, Outlook, Rackspace, or other service, to receive emails from an alias address that includes your domain name. This is ideal for individuals and small businesses concerned with maintaining a professional online reputation without incurring email hosting fees.

In simplest terms, using our forwarding tool, you can create an address like [email protected], share that email address on your site (or anywhere you want, really), and we will forward emails sent to that address to your Gmail, Outlook or other email address.


Do not remove or change any existing MX records from your DNS unless you are certain it is safe to do so.

Creating A Forward

Click the Emails tab, then click Email Forwarding to open the email forwarding creation and management tool.

Note the following information, displayed on that screen, which you may need to configure a forwarding address:

Record Type: MX
Name/Host/Alias: @ or leave blank
TTL: 3600
Priority: 1


You can only configure one forwarding address at a time, but you can add as many as you like. If you want to forward multiple addresses to a single account, simply create an email forward for each using the same “forwarded to” address.

Click the Add email forward button in the bottom left corner. In the screen that appears, enter the following information into the fields provided:

  • Email Sent to – In this field, enter the user portion of the address, which is everything before the @. Do not include the @.
  • Domain – In this field enter the domain portion of the email address, which is everything after the @. Do not include the @.
  • Will be forwarded to – Enter the entire email address to which you want emails forwarded.

When ready, click the Add button.

email forwarding config

Verify the Forward to Address

Within a few minutes, WPMU DEV will send an email to the forwarded to address that contains a verification link. You must click this link to activate forwarding for the newly-created address.

Configuring Forwarding MX Records

The verification email also includes important instructions for editing the DNS information for the applicable domain. Typically, these records are maintained by the registrar where you purchased your domain, unless you are using our DNS management tool, which we strongly encourage.

You can find guidance on working with the DNS records for several popular DNS registrars here.

It is important to note that once you edit DNS, it may take some time (up to 24 hours in rare cases) for the DNS changes to take full effect and for the email forward to begin working.

10.5 Using SMTP To Send Emails

Copy chapter anchor to clipboard

The easiest way to avoid our sending limits or to change the From email address on transactional emails is to use our Branda plugin, which has an easy SMTP tool built right in :)
