Gmail offers several options for sending emails, whether in small batches or larger volumes. Let’s explore how to make the most of these possibilities.
1. Sending Emails via Gmail’s Web Interface
The simplest method is using Gmail’s web interface. This is ideal for sending a smaller number of emails, up to a few hundred. If you follow the guidelines for avoiding spam filters (details: How to Avoid Your Newsletter Ending Up in the Spam Folder), you can successfully send around 50 emails per day from the same template, staying within Gmail’s theoretical daily limit of 500 emails.
2. Gmail Business Plan
With a Gmail Business subscription, the daily sending limit increases significantly, allowing up to 2,500 emails per day. The principles and tips for avoiding spam filters remain the same as those discussed in the previous section.
3. Using Gmail’s SMTP
Another effective method is to utilize Gmail’s SMTP server. For this, you’ll need a web server, such as Apache or Nginx, which can either run on a hosting platform or be set up locally. For local development, the easiest approach is to use the XAMPP developer server, which also supports running PHP scripts.
SMTP Configuration in PHP:
phpKód másolása// SMTP connection settings for sending the email
$phpmailer->isSMTP();
$phpmailer->Host = "ssl://smtp.gmail.com";
$phpmailer->Port = 465;
$phpmailer->SMTPAuth = true;
$phpmailer->AuthType = "LOGIN"; // 'CRAM-MD5', 'PLAIN', 'LOGIN'
$phpmailer->SMTPSecure = "ssl";
$phpmailer->Username = "your@gmail.com";
$phpmailer->Password = "12345";
When using Gmail’s SMTP, the daily sending limits are the same as those for the web-based Gmail.
4. Advanced Solutions: Database and Content Rotation
The PHP script mentioned above can be extended with a MySQL database to store email addresses. Additionally, content rotation techniques can be implemented to ensure that the emails have varied content. This approach is highly effective for avoiding spam filters, as each sent email is unique while remaining relevant.
