If you’re a solo founder, an indie hacker, a bootstrapper, a webmaster, a developer or if you have multiple domains, and/or you need to manage multiple inboxes, then this article might be perfect for you.
We’ll show you how you can send and/or receive emails in your Gmail with your custom domain email addresses.
Here’s how to get started. If you need help, just send us an email info@kingmailer.co:
Create Endpoints
An Endpoint is where you want the emails to be delivered, it can be your Gmail-address. In your Kingmailer-account go to Routing (1), click on Address Endpoints (2) and then on Add your first address endpoint (3).
Enter your email address
Enter your email address (1) and click Create address endpoint (2).
Create a Route
The Endpoint is there, so now you can create any email address you like, all emails send to this address will be delivered (forwarded/routed) to the Endpoint aka your Gmail address.
Enter a username (1) for your email address for example info@domain so there you’ll enter just info. Select the domain (2) (which you already verified in your account: SPF, DKIM, MX and Return Path). Choose the Endpoint (3) which you created earlier.
Sending Emails from Gmail
Go to Settings > Accounts and Import > Add another email address > Send mail as
Add your email address
Enter your name and your email address, allow Treat as an alias and then Next Step
Enter the SMTP credentials
You can use these settings:
SMTP Server: kingmailer.org Username: enter your SMTP username Password: enter your SMTP password Port: 587, 465, 25 or 2525 Secure connection: TLS
So there you have it, you can send and receive emails in your Gmail using your own domain. Create as many email addresses you want, have the emails delivered to your Gmail, at no extra costs.
In this tutorial I have worked with Gmail, but you can use any other provider such as Hotmail, Yahoo or Proton etc.

FAQ

Send us an email to upgrade your account.
How does Kingmailer work?
Kingmailer is an email delivery and deliverability service that empowers businesses to easily send email from their (web) apps. It’s free to sign up and easy to get started.
How does your billing work?
You will be billed every 30 days. We accept PayPal and all major credit and debit cards. Your payment info is stored and processed securely by 2Checkout and never touches our servers.
How do I send emails with Kingmailer?
Since Kingmailer has both an HTTP API and an SMTP endpoint, you can choose to send the way you’d like. Both ways have their advantages… SMTP is easy to setup and often plug and play, but API is much more reliable at scale. If you’re building an application, we recommend using our HTTP API.
How many dedicated IP’s do I need? Can I get more?
You don’t actually need a dedicated IP when using Kingmailer, because great email delivery is already included in your plan, no additional investment is needed for this from your end.
How many users come with each plan?
Every Kingmailer plan (free and paid) allows you to add as many users as you need to your account at no additional cost. We think it’s much easier this way to manage the account with your team, without sharing login credentials.
I want to test Kingmailer first. How can I do that?
The free trial is ideal for those looking to test out the service. Keep in mind that the free trial has a max 20 emails per hour limit and a max 20 recipients limit. If you reach these limits, your email traffic will be paused. The free plan has 30 days of log retention so you can easily troubleshoot issues.
Kingmailer solves your spam (inbound or outbound filter) problem with its build-in Spam filter. Kingmailer uses SpamAssassin – an open source solution for combating email spam (unsolicited bulk spam).
