KingSMTP is a cloud-based transactional email service that provides businesses with a stable SMTP infrastructure for sending critical system-generated emails. The platform is designed exclusively for transactional use cases and does not support bulk or marketing campaigns. KingSMTP allows applications, websites, and backend systems to send emails through standard SMTP connections or API-based integrations. Typical use cases include account-related emails, password resets, system notifications, invoices, receipts, and welcome emails. All outgoing emails are logged and tracked, enabling auditing and troubleshooting. KingSMTP focuses on predictable delivery, transparency, and operational reliability rather than marketing automation features. Customer support is provided via email. Previously known as Kingmailer, KingSMTP continues to deliver trusted SMTP solutions to businesses, SaaS platforms, and developers. ## What is KingMailer used for?

" 4.0 Overall Rating 4.0 4.0 Ease of Use 5.0 5.0 Features 4.0 4.0 Customer Service 4.0 4.0 Likelihood to Recommend 9/10 March 24, 2019 I have many email marketing campaigns for my company with a good conversion rate. This is an excellent tool to use at such a low price. I would recommend this tool to startups and small businesses out there! Pros Kingmailer is an excellent tool to run innovative and customizable email marketing campaigns. You can easily create great email marketing campaigns to increase the conversion rate. It is super easy to use with a great user interface. If you're low on budget, you can use this tool to create low-cost email marketing campaigns with high conversion rates. Cons The spam filtering tools can be made more powerful. It is not as efficient as the big players in the market but, still, we can ignore this fact while considering the low cost they're charging. Once, my important mail sent into the spam box, so this should be improved.

It has worked to reduce costs since it is lower than other market options. Pros It is a simple software that does what it promises, sending email marketing campaigns at a low price. Cons Comparing the price with the competition we can see that it is economic. For this reason we can not demand as much as others. Putting aside this aspect, we can not expect a great deliverability rate with this program. Neither spam filtering nor very sophisticated features.

If I couldn't manage something quickly, the customer support did it for me, and instructed me how to use the software.

Pros Simple User Interface, Easy to use, Multiple applications (lists, etc.), good basic reports on conversion per campaign. Cons Lacks certain marketing tools still.
