Sendgrid alternative

Why choose Kingmailer over Sendgrid?

Sendgrid offers a lot of features that most user will never touch… even for us, when browsing through their features, we were constantly asking ourselves: Why isn’t their product more simple? It’s like buying a gaming pc, but only using it to browse the web or write documents. You’re paying too much.

Their Essentials plan (cheapest what they offer, $14,95 p/mo), only gives 3 days of Search email activity… this can never be enough, forcing you to buy more days. A dedicated IP must be purchased (price $89,95 p/mo) just to have decent inbox email delivery, but why though? Why isn’t good email delivery by default? What do you think? Leave your comment below.

Kingmailer offers a much more simpler interface and much much faster setup to start sending and receiving emails.

Rated on Capterra Kingmailer vs Sendgrid


How does Kingmailer work?

Kingmailer is a cloud-based SMTP provider that acts as an email delivery engine, allowing you to send email without the cost and complexity of maintaining your own email servers. Kingmailer manages the technical details of email delivery, like infrastructure scaling, ISP outreach, reputation monitoring, and real-time analytics.

How does the free trial work?

You can send 20 transactional emails to max 20 email recipients with your free account, which is perfect for testing purpose. If you need to send more than that, you can easily upgrade to a paid plan.

How do you measure the number of emails I send?

Every time you send one email to one recipient, it’s deducted as one email credit from your paid plan. This occurs whether the email is ultimately deferred or sent to spam by the inbox provider.

What happens if I go over my plan?

If you send more emails than your plan allows within a given billing period, you will be charged a small overage fee on a per-email basis. Any overage fees are added to your invoice for the following billing period.

Can you help me get started? Do you offer deliverability consulting?

Yes! We can walk you through the entire set-up process to ensure that your email environment is built for success. You don’t need deliverability consulting with Kingmailer as your emails are designed to land in user’s inboxes.

Why do I need to verify my account?

We only ask you do this by email, just click on the activation link to verify your account. No credit card is needed for this.
