Troubleshooting | Unable to Send or Receive Email


Note: As part of our commitment to staying up-to-date with industry security standards, we will be disabling access to our legacy email system over the TLS 1.0 protocol beginning the 30th of April. This change should only affect legacy customers who are still using our integrated email solution and should not cause any loss in data. However, if your current email client is not set up to support the newer TLS 1.1/1.2 protocols, then you will need to re-setup your email accounts. We have step-by-step guides for you provided here.


Before following the steps below, double-check the following.

Troubleshooting Email Settings

Once you’ve determined that you are using a supported email client, BigCommerce is hosting your email, and there are no problems with the server, you’ve narrowed down the issue to your email account information or the server settings.

Check your email account login information

1. Are you using the correct username? It should be your full email address (e.g.

2. The password should be the one you set up under Server Settings Email Accounts. This is not necessarily the same as your store login.

3. Reset the password. To reset, go to Server SettingsEmail Accounts, edit the email account, and type the new password in both password fields. Save your changes, then attempt to reconnect.

Email Account Details

Check the server information

1. Go to Server Settings  › Email Accounts. Next to your email account, select the Action iconAccount Details. Make sure you are using the servers listed under Incoming Server and Outgoing Server. It should contain (e.g.

2. Make sure that you have the correct ports entered in your email client.

Server TypePort
Incoming (POP)995
Incoming (IMAP)993
Outgoing (SMTP)465

Check SSL Authentication

Your email client will give you the opportunity to authenticate using SSL for both incoming and outgoing mail servers. Make sure SSL is checked for both.

Additional settings

Do you have any additional settings your email client requires?

Some email clients require additional settings that are required before you connect. Read through your email client’s tutorial listed below to make sure that you have any additional requirements set up correctly.

If you are still unable to connect to your email server, the issue may be with your ISP, or internet service provider. Try contacting them to make sure there isn’t an issue with your store’s or BigCommerce’s IP address being blocked.

If this is the case, we recommend using a 3rd party email provider such as G Suite (formerly Google Apps) or Zoho Mail. These services also provide webmail and are instantly set up and ready to use.

Supported Email Clients

  • Outlook 2010
  • Mozilla Thunderbird
  • Apple Mail
  • iOS Devices
  • Windows 7 Devices

You can also set up your email through Gmail.

It often helps to try setting up email in another client, in case there is an issue with the email client you are trying to use. Thunderbird is an excellent free alternative.

Some mail clients that previously worked with BigCommerce are no longer supported as a result of the POODLE SSLv3 vulnerability.

Is BigCommerce your email host?

Check whether BigCommerce is set up to host your email by looking at the MX records in your control panel. MX Records DNS record that control where email is hosted. If you are not using BigCommerce MX records, you will be unable to connect using BigCommerce credentials because your email is being hosted by another service.

1. Go to Server SettingsEmail & DNS Records.

2. Under the Mail Servers tab, you should see MX records that look similar to the image below. Specifically, the value must contain

If your MX records are not hosted with BigCommerce, contact the service that is hosting them for instructions on setting up email.
