If you plan to send multiple emails at a time or more than 500 emails per day you may want to consider using SendGrid or similar mass-mailing service instead to avoid sending failures. This article explains how to send emails via SendGrid SMTP, but a similar approach may be applied to other mass-mailing services.

Obtaining SendGrid API key

To obtain the SendGrid API key, please sign up for a SendGrid account:

After that, please follow these steps:

  1. Navigate to Settings on the left navigation bar, and then select API Keys.

  2. Click Create API Key.

  3. Give your API key a name.

  4. Select Full Access, Restricted Access, or Billing Access.

  5. If you're selecting Restricted Access, or Billing Access, select the specific permissions to give each category. For more information, see API key permissions.

  6. Click Create & View.

  7. Copy your API key

Setting up SMTP in Mapsly

After successfully creating a SendGrid API key, you will need to configure your SMTP credentials in Mapsly. To do that, go to Setup > Actions > Email settings:

There, you will need to insert the following information:


Port: 587 (TLS)

Username: apikey

Password: your SendGrid API key that you created in the previous step

That's it! Now you should be able to send emails using SendGrid SMTP server. If you have any questions feel free to reach out to Mapsly's support via [email protected] or live chat.
