        Why do I need a service like Mailgun or SendGrid?

        Email applications like Microsoft Outlook, Apple Mail, and Close make drafting, sending, and receiving email easy.

        Regardless of what app or service you're using, all of the sending and receiving actions happen on your email server - and every email server has a limit on how many messages it will allow you to send each day.

        Depending on the maximum outbound email limit of your email server, if that threshold is reached, your email server will stop sending all emails from your email account - from Close or otherwise. Bulk email tools like Mailgun or SendGrid enable you to send large quantities of emails without the risk of your email server halting your outbound emails that day if you exceed the email server's daily quota limit. As an example - take a look at GSuite limits here.


        Although Mailgun, SendGrid, and others are better suited for bulk email sending than Gmail, it doesn't mean they offer unlimited email sending. They also have limits in place to prevent spam/abuse. Read more on Mailgun's probation period.

        When registering with any such service, please make sure you know your hourly/daily sending limits to avoid being disconnected from Close.

        Mailgun, SendGrid, and other 3rd party email services are usually used for sending out Email Sequences and Bulk emails.

        Read this first

        Mailgun and SendGrid are two of many powerful 3rd party email services that work well with Close, yet the team here at Close doesn’t maintain them. We’ll always do our best to help out, but the email functionality email providers offer happens outside the Close application, and likewise outside our control and visibility. If you need additional help with Mailgun or SendGrid, you'll probably need to contact Mailgun or contact SendGrid.

        Modifying DNS records

        We also wanted to kindly warn that the steps below require experience administrating Domains and DNS records. Incorrectly modifying DNS entries could prevent your organization from sending and receiving all email, take your website offline, and possibly halt other services from running properly as well. These steps are best performed by your IT provider or support team.

        You'll need your domain host credentials

        You’ll need your administrative username and password to log into your domain host ("domain registrar") to make DNS changes. Your domain host is typically the company from which you purchased your domain name.

        Companies like GoDaddy, NameCheap, Network Solutions, Rackspace Email & Apps, Digital Ocean , Google Domains, and others are common domain hosts and registrars.

        Not sure who hosts your domain? You can often find out by searching for your domain here and viewing the registrar field.

        Email server setup

        Once you have your DNS editor ready, follow the steps depending on your email server provider:
