Submit Form to Auto Send Emails (With Complete Codes)

We have developed a fully functional code file for sending emails through a contact form. To use this file, you will need to obtain the `app_key` and `template_id` from AOTsend. This article is divided into two parts: the first part guides you through the process of acquiring the `app_key` and `template_id` from AOTsend, while the second part includes the complete code for the email-sending functionality. With these instructions, you'll be able to set up and use the email-sending feature efficiently.

How to obtain the `app_key` and `template_id` from AOTsend?

1. Register for an account on the AOTsend Email API Platform.

2. Bind your domain and complete domain verification. After verification, it will automatically be submitted for review. Wait for the review to be approved.

3. Set up an email template. AOTsend offers high-quality, minimalist templates suitable for various uses.

4. Obtain the app_key and template_id from steps 2 and 3. (If unclear, contact AOTsend support.)

5. Download the PHP file (source code for automatic email sending via Contact Form).

6. In the PHP file, replace app_key and template_id on line 31 with your own. Also, specify the email address where you want to receive emails.

7. Place the PHP file in your website directory and access it via URL.

8. Submit a test form to ensure emails are received in your specified mailbox. Check your spam folder if using a new domain.
