What is E-mail to SMS?

Email to SMS is a communication service that facilitates the transmission of text messages from email accounts to mobile phones through the SMS protocol. Users can compose messages in their preferred email clients, substituting the recipient's email address with their mobile phone number followed by the domain of the SMS gateway provider. The SMS gateway then converts the email into an SMS format and delivers it to the recipient's mobile device. This method is often utilized for sending notifications, alerts, and other text-based messages seamlessly from email platforms to mobile phones, providing a convenient bridge between different communication channels.

In practical terms, Email to SMS is advantageous for users who prefer the familiarity and ease of sending messages from their email accounts. This service is commonly employed in various scenarios, including business communications and automated alerts, streamlining the process of reaching individuals through traditional SMS on their mobile devices.

What is the difference between E-mail to SMS and SMS to E-mail?

Email to SMS and SMS to Email represent two distinct communication services that bridge the gap between email and SMS protocols but operate in opposite directions. Email to SMS allows users to compose emails in their preferred email clients, substituting the recipient's email address with their mobile phone number followed by the domain of the SMS gateway provider. The message is then converted into SMS format and delivered to the recipient's mobile device.

On the other hand, SMS to Email enables users to send text messages from their mobile phones to an email address. The SMS is received by an SMS gateway, converted into an email format, and forwarded to the specified email address. These services cater to different communication preferences, with Email to SMS facilitating the seamless transition from email to SMS, and SMS to Email allowing users to manage SMS messages within their email inbox.

The second approach is to configure your SMS gateway as an E-mail client. When you go for the first approach, your SMS gateway will become part of the e-mail network as a standard e-mail server and will be able to provide service throught SMTP (Simple Mail Transfer Protocol) as any other E-mail server does. In the second approach, your SMS gateway acts like an e-mail client, like Microsoft Outlook or Windows Mail, and downloads and uploads E-mail messages from traditional E-mail servers. Both approaches have advantages and disadvantages, and Ozeki SMS Gateway can be configure to work in both ways. The approach you will choose is going to be determined by the E-mail server you currently operate. In the second part of this article, you will find details instructions for the most common e-mail servers. It is highly likely, that you will find your e-mail server there.

How to convert phone numbers to e-mail address and vica versa?

An E-mail to sms system takes an e-mail you send and forwards it to a mobile phone as an SMS message. The major question for such a system is how do you provide the phone number where the SMS should be sent to in your e-mail message.

Regarding the other direction when sms messages are forwarded to e-mails the question is usually easier. The SMS is either a reply to a previously sent e-mail, or it can be forwarded to a previously configured e-mail address or to multiple e-mail addresses. E-mail address configuration for this optin is available in the SMS gateway.

How to set the mobile phone number in an E-mail message?
