Contact Form 7 is one of the most important and popular plugins for WordPress. Whether you are a WordPress user or not, you may have already probably heard about Contact Form 7. The Contact Form 7 plugin is the most popular plugin within WordPress for managing contact forms. The plugin has more than 5 million subscribers, and it gives users easier use of contact forms, as well as for them to reach their clients quicker and easier.
Sometimes, the Contact Form 7 plugin may not be working properly, which can cause frustration. One issue you may encounter is that Contact Form 7 may not be sending emails properly. In this article, we will take a look at why it happens, and walk you through a tutorial on how to set up Contact Form 7 so that it sends you notifications regarding messages from new contacts, and allow you to be able to apply directly to the sender of a message through email.
So, why is your Contact Form 7 not sending emails? To better understand, you must first analyze whether your WordPress server, or the server on which you host your connection, is optimal. Contact Form 7 depends heavily on these two facts, and you should investigate that first. To send emails that are generated by WordPress, Contact Form 7 uses the PHP mail function. The issue might be in the hosting servers themselves, as many of them do not use the feature of the mail function.
Emails are often prevented by spam filters. These are smartly configured to reject any emails that come from questionable sources, even though they might actually come from reputable sources. Many reputable email providers reject potentially harmful emails by using a spam filter, and this is what might be happening to your Contact Form 7 emails.
Big companies and email providers, such as Yahoo and Gmail, often contain a filter that blocks all mail from questionable sources or any mail at all. For this reason, you may get the error of Contact Form 7 not sending emails because it is blocked by an email provider. These big companies use software that prevents as much spam mail as possible and reserve themselves from using PHP mail forms. This is likely the reason your email will be blocked by these providers.
Some of these tools have really restraining protocols of checking the origin of the email, and your WordPress emails could be being blocked by the email provider.
Perhaps Contact Form 7 is not sending emails, but your client had no problems with sending it. For the solution to this problem, you should examine your configuration of the plugin. The problem is likely not the plugin itself, but in its configuration. Your IP address (from the site that is sending emails) is likely not part of the sender’s domain. The mail server that is receiving the email does a DNS lookup to check whether the IP corresponds to the IP of the sender.
This lookup will result in failure if the from uses the sender’s email address without providing additional input about the origin of the email. The sender’s address is often set to your own address rather than the address of your WordPress site. This is set in the default settings, and the email provider will likely reject any emails sent from your WordPress site because it is not sent from your own address.
Unfortunately, there are a vast number of scams circling the internet that do occur in such a way, which is why big companies protect themselves by not receiving emails from addresses that are not the same as the address in the configuration.
The issue of Contact Form 7 not sending emails may likely be due to its configuration.
Sometimes, the solution to this dangling problem is a simple one. The “From” section of the settings needs to be set to the same email that is used by the server. To make the change, open the “Mail” tab, then open the “From” section. It is the address under the “From” section that determines whether the email can be sent or not.
To solve the problem, it is essential to use an email with the same domain as the server of your WordPress site. The correct email address should be entered in the from section of your configuration.
Here is how the settings would look like if they are done correctly:
From: [email protected]
(Please note that the email address should be your email address and the domain should be the same as the WordPress server)

Another possible solution would be to add another two email headers – A “ReplyTo” header and a “Sender” header can help clear up the confusion.
Sender: [email protected]
Reply-To: username <[user mail]>
The email under the sender section should have the same domain as your server, while the replyto email is the sender’s email address.
These settings can clear up the confusion for the mail server, and it will prevent it from getting blocked by informing the mail server that it was sent by the website on your behalf, but your email might still end up in the spam filters as this solution is not 100% guaranteed to work. However, it can clear up the confusion and might prevent your email from not getting sent.
Most sites use PHP to send emails – the WordPress interface uses PHP to send emails, as does the plugin. But some sites do not use it, and that might be causing the problem as well. To avoid this, you can use an SMTP plugin.

It can be used for sending and receiving emails from clients, and it can help you massively to avoid Contact Form 7 not sending emails to your clients. Because it offers a safe connection, your emails will not get blocked.
As an alternative method, you can use a ready contact form template and embed it to your page easily without having to use a plugin.
