    Easy to troubleshoot emails

    In your KingSMTP dashboard, you can click on each email to troubleshoot. KingSMTP logs and retains data of your emails, this is very useful when you need to troubleshoot your emails.

    Here are a few screenshots to give you an idea:

    Incoming messages
    Spam check
    Spam status
    Extra details of your message
    Spam Check details
    Spam score

    This is already pre-configured in your account, give it a try.

    For example you have 5 domains, but you want to manage 1 email inbox. You want to send and receive emails from a single email inbox.

    This is the way to go. To illustrate this…

    These are the fictive email addresses you have from the 5 different domains:

    info@FirstDomainname@FirstDomain
    info@SecondDomainname@SecondDomain
    info@ThirdDomainname@ThirdDomain
    Etc
    Your project domains.

    Below is the email address that you want to use:

    John@Gmail.com
    Your Gmail address that you use daily.

    So in your Kingmailer-account, you can create MX Email Routing / Forwarding, and have this setup, so all emails send to different recipients, all get delivered to your primary email inbox.

    We have a step-by-step guide on how to setup MX email routing using your own domain.

    We will assume you have already signed up for a free Kingmailer account, and have already setup your domain. (SPF, DKIM, MX and RETURN PATH)

    First thing after adding/verifying your domain in your account is, to create Endpoints.

    Follow the steps below to create an Endpoint, from Step 4 we explain how to send emails from Gmail, so not just to forward emails:

    Here’s how to get started. If you need help, just send us an email info@kingmailer.co:

    4. Sending Emails from Gmail

  • A transactional SMTP service for your app

    Send important transactional emails like password resets, order confirmations, and more with a reliable SMTP service. Avoid the hassle of maintaining your own email infrastructure while ensuring timely delivery of your emails.

    Key features of a transactional SMTP service

    Sending a few emails a day is generally manageable, even if you’re reaching dozens of people. Services like Google’s Gmail limit email sends to 500 per day, and many shared hosting providers also impose email caps. While this might be fine for personal use, sending hundreds or thousands of transactional emails daily can easily exceed those limits.
    For businesses sending bulk emails or transactional messages to large audiences, cloud-based SMTP services provide the necessary scalability. With services like KingSMTP, you can send transactional emails to any number of customers, triggered by their actions on your site, all without managing your own SMTP server. KingSMTP offers seamless setup and integration for your transactional email needs.

    Email servers vs. cloud-based SMTP services

    While managing your own email server is an option, sending large volumes of emails—whether transactional or promotional—can be technically demanding. Managing email servers at scale can consume valuable developer time and require significant resources to handle email traffic.
    Many companies, even those that run their own email servers, often choose to rely on a dedicated SMTP service for transactional emails. The ease, speed, and reliability of using a service like KingSMTP make it an attractive alternative. KingSMTP offers a ready-to-go SMTP relay and a customizable email API for developers seeking more control over email delivery.

    Ensuring reliable delivery

    Sending emails is only half the battle—ensuring they’re actually received is just as important. Without strong deliverability and tracking mechanisms, it’s difficult to know how many of your emails will bypass spam filters or avoid bouncing. Testing your own servers might help, but it can be time-consuming and may not provide all the insights you need.
    A robust email service should not only help you scale your transactional messages but also ensure high deliverability rates. KingSMTP enhances deliverability with domain name authentication and email address validation, reducing bounce rates and preventing spam complaints. For companies requiring the highest delivery success rates, KingSMTP’s managed service provides personalized support and proactive monitoring to optimize performance.

    Maximizing the impact of transactional messages

    Great email marketing feels personal and relevant. Transactional emails—whether they’re password resets, order confirmations, or account updates—can be a key part of your marketing strategy. Tailored, responsive, and relevant transactional messages can help increase customer engagement.
    With KingSMTP, you can take your transactional emails to the next level by conducting A/B tests and analyzing key events like click-throughs. The platform’s real-time analytics, including open and click tracking, allow you to continually optimize the performance and effectiveness of every email you send.

    FAQ

    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 Bitcoin, 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.
