Deliverability:

External SMTP servers have a better reputation than shared servers that are often used by web hosts. This means that your emails are more likely to be delivered to the recipient’s inbox and not be flagged as spam.

Scalability:

External SMTP servers can handle a large volume of emails without impacting your website’s performance. This is especially important if you have a large mailing list or need to send transactional emails.

Advanced features:

Many external SMTP servers offer advanced features such as email tracking, analytics, and automation. These features can help you optimize your email campaigns and improve engagement with your audience.

Security:

External SMTP servers often have better security measures in place than shared servers. They use encryption to protect your emails from being intercepted and ensure that your data is safe.

Overall, using an external SMTP server can improve the reliability, deliverability, scalability, and security of your email campaigns.
