WordPress is built using PHP, that’s a coding language that’s usually used for net development. WordPress’s content material control gadget (CMS) uses this programming language for most of its core functionality, which include sending emails.
You can send emails the usage of a custom address along with your internet site’s domain call. Not simplest does this assist you have interaction with clients via e-mail, however it also lets you do so while staying on-logo by sending messages from www.Yourdomain.Com — instead of a private inbox.
However, every now and then WordPress’s e-mail feature isn’t the handiest because of the way that it’s coded. If you persist with the default PHP mail function, some of your emails would possibly never make it to their locations due to how certain servers are configured.
For WordPress Admins
Some website hosting providers disable the PHP electronic mail function altogether so customers can’t abuse their offerings and send junk mail emails. However, that leaves you in a bind. If your WordPress site can’t use the PHP mail characteristic, you and your users will leave out out on vital communications, which include:
Signup or e-mail exchange confirmations
Lost password emails
Purchase confirmation messages
Email notifications from plugins
Update notification emails
Although you could use WordPress with out sending or receiving those messages, it can create complications to your crew in the long time. For instance, in case you lose your password, you received’t be capable of use WordPress’s default account recuperation system. You’d need to exchange it manually through your database.

Some internet hosts do support PHP e-mail. However, your best wager is to apply a extra secure approach to ensure your messages are brought. That’s wherein SMTP comes into play.
What is Simple Mail Transfer Protocol (SMTP)?
Usually, servers fulfill very precise functions that they’re configured for. That’s why a few internet website hosting servers don’t aid email at all.

Sending and receiving emails
Relaying outgoing mail
Ensuring a excessive e mail transport charge
Although you can use most electronic mail offerings totally free, in case you need to send transactional messages from a internet site you might need to pay for a top class plan. For example, in case you ship transactional messages in mass from a regular Gmail address, many email carrier companies will logo those messages as spam. To keep away from that, you’d need to apply some thing like a Google Workspace account, which gives an SMTP service which could manage transactional emails.

Option 2: Connect to your SMTP provider via its API.
Technically, we used the Gmail API during the last approach to attach our electronic mail carrier issuer to WordPress. However, if you’re the usage of a dedicated electronic mail advertising service or SMTP provider, you won’t want to set up a web app to connect WP Mail SMTP to its API.

However, if you ship any form of email which you think may warrant a reaction, you’ll need to make certain that subscribers realize to which cope with they can truly publish questions to.
The sending domain (which comes after the @) have to be the same as your internet site’s. SendGrid will ask you to verify your sending area before you may use it to deliver transactional emails.
Once you do, SendGrid will have you create an API key that you could use to connect the platform with WordPress.

Overall, that’s how the API integration method works with maximum e mail provider companies. On the alternative hand, in case your SMTP issuer doesn’t provide API get entry to (that’s uncommon), you’ll need to use the guide method.
Option 3: Configure Your WordPress SMTP settings manually.
Both of the preceding SMTP integration techniques are available inside the WP Mail SMTP configuration wizard and its regular settings web page. However, you are not restricted to these integrated integrations.
You can manually join different SMTP services manually through the wizard, or via the plugin settings as depicted underneath.
Manual SMTP installation
It’s vital to note that we don’t propose this method except the SMTP company which you choose isn’t supported by the plugin out of the box. In that case, you is probably better off the usage of a distinctive WordPress SMTP plugin that does provide direct integration with your preferred platform.
That’s because by the use of this approach, you’re storing your email service credentials within your WordPress web page’s database. This is much less comfy than the opposite methods. For higher security, you could including your SMTP Username and SMTP Password for your website online’s configuration file the usage of constants. However, this requires you to feature a few code for your site’s wp-config.Personal home page file, which may be intimidating for novices.
If you are at ease editing your core documents and want to connect an SMTP company with WordPress manually, the plugin will ask you for the subsequent statistics.
