Setting Up SMTP

If you are on a branded plan with Grow, you can set up your SMTP information so Grow can send emails using your email service. This makes it so when you add a new user, the email will come from friendly@yourcompany instead of

If you would like to add this feature to your account, talk to your Grow account manager or visit your account's billing page.

We recommend using the Email Setup Instructions instead of using SMTP. However, if you choose to use SMTP instead, you'll find the instructions below.

First, log in to Grow. Go to your Settings and navigate to the Mail tab.

From here, there are two options to setting this feature up. The two sections are SMTP and Email Setup.

If you would like to use Email Setup, refer to this article.


If you are using the SMTP option, below are details about what you will need to enter into the fields in the SMTP section.

Host and Port

First, the host and port you enter depend on what service provider you use for your emails.

For example, SendGrid suggests port 587, while Mailgun suggests port 587 or 465.

If you are using Gmail with TLS, you will probably use 587. If you use SSL, the port will be 465. If neither of those work for Gmail, try using port 25.

Because there are many SMTP providers and settings, you will have to rely on your email service provider for documentation and easy answers about what host and which port to use. For example, if you use Mailgun, you can find your SMTP credentials for each domain on your domains tab.

If you need help with this step, please contact us via email or chat and include the host that you use.

From Email

Set the from email field. This is the email Grow emails will send from, and which your customers will see. Make sure that the from email address is set up in your system and can receive replies.

User and Password

The username you enter can be either your full email address or just the first part of your email, before the @ symbol. This depends on what your service provider allows.

For example:
SendGrid allows just the username before the @ symbol:

  • Email:
  • Username: johndoe

On the other hand, Office 365 uses the full email:

  • Email:
  • Username (User):

In the password field, enter your password for that email.

Gmail and Google Apps

If you use Gmail and Google Apps to send out your business email, you will need to go through a couple additional steps.

Google has set some special rules regarding third-party access to your account. For Google to authorize a third-party server to access your account via SMTP, you have to enable Less Secure Apps on your Gmail account.

Essentially, any apps that are not using security protocols that Google deems mandatory will be blocked, unless you enable the ability for less secure apps to access your Gmail account.

Please do not enable the Less Secure Apps access unless you fully understand the process and the possible ramifications of the action.

If you decide not to enable Less Secure Apps, you can use a different SMTP client to send your emails. There are great services like SendGrid, MailGun, Mandrill, or MailSender. These can be configured to send email from your domain.

This is a Google decision, and Grow can't fix or do alternative mail setup for you. The administration of your mail service would be taken care of by your developers or technical team.

The branded plan was previously called a white label (or whitelabel) account or plan. These refer to the same account type and plan.
