Questions the author answers
Is SureMail really free?
Yes! SureMail is 100% free and open-source. It’s our way of giving back to the WordPress community, offering a reliable solution for email delivery without any cost. We believe in helping WordPress users succeed with effortless, fail-proof email delivery.
How does SureMail ensure email delivery?
SureMail ensures fail-proof email delivery by allowing you to set up multiple SMTP connections and fallback providers. If your primary SMTP provider fails, the plugin will automatically switch to secondary connections one after another. Plus, it retries failed emails after a set time, ensuring that your emails have multiple chances to be delivered.
Can SureMail handle high email volumes?
Yes! SureMail is built to scale, allowing you to handle large volumes of email without compromising on reliability. With multiple SMTP connections and fallback mechanisms, it ensures your emails get delivered even when traffic or email volume spikes.
Will SureMail slow down my website?
Absolutely not! SureMail is built with ease and performance in mind. Its architecture and clean code keep it lightweight and fast. Therefore, it will not affect your website speed and performance in any way.
What are the requirements to use SureMail?
You only need to have the latest version of WordPress on your website, to begin with. SureMail is basically a plugin like any other WordPress plugin. Therefore, the latest WordPress installation along with a theme is enough to begin with.
How do I configure SureMail on my WordPress website?
Configuring SureMail is easy. Simply install the plugin on your WordPress site, then navigate to the Connections page where you can input your SMTP provider credentials. SureMail supports multiple SMTP providers, so you can choose the one that works best for you. You can also configure fallback connections and email failure notifications for a more reliable setup.
