If you need to send emails from your website (regardless of whether it is built in ASP, ASP.NET or PHP), you should configure your site to send emails via the SMTP server websmtp.simply.com (port 587). There is no limit on the number of emails sent from websmtp.simply.com.
To send through websmtp.simply.com you must use port 587 (STARTTLS is supported), and log in to the server with username and password. The login credentials can be any mail address set up in your Simply.com Mail Administration.
This server can only be used by your scripts, from our web servers, and not by standard mail clients or from servers located elsewhere.
In CMSs (Wordpress, Drupal, Prestashop, Magento etc.) you can often specify an SMTP server, or install a plugin that makes this possible.
If you choose to send emails via PHP's mail() function the emails WILL NOT be DKIM/SPF‑validated by the recipient and will therefore likely be regarded as spam. In other words: use our SMTP server.
In PHP you can use the following libraries for sending, as the mail() function does not support sending via an external SMTP server.
We recommend the plugin http://wordpress.org/plugins/easy-wp-smtp/
See http://doc.prestashop.com/display/PS16/E-Mail+Parameters
We recommend the plugin https://github.com/aschroder/Magento-SMTP-Pro-Email-Extension
We of course do not allow websmtp.simply.com to be used for phishing, spam, address harvesting or any other type of mail sending that is a nuisance to the recipient or that generates complaints from us. Our SMTP service is available to help our customers run their websites and related services, so good reputation and delivery are a priority for us. See our terms for details.
If you need to send tens of thousands of emails, we do not recommend using websmtp.simply.com for this. We crack down hard on spam and misuse of the server to ensure our servers and other customers are not blocked because of spam or bulk mailings.
Ensure SPF, DKIM and DMARC are set up for your emails and domain; this helps prevent mail blocking by many providers.
Consider using third‑party services such as, for example, Mailgun for bulk sending; this gives you the best delivery.
For bulk mailings we always appreciate customers handling their bounce emails and removing ‘dead’ addresses from their lists. This can be done by setting up a sender account and checking that account for error mails/bounces. If such an account is set up, you should also disable antivirus and antispam on the account, as otherwise a significant amount of unnecessary resources will be used on our mail servers. Ensure you empty and process the mailbox regularly.
This will prevent mail servers from blocking emails sent from our SMTP servers, and ensure your messages are delivered correctly to valid recipients.
Also implement the List‑Unsubscribe header so it contains a link that directly removes the recipient from any lists, and otherwise follow good practice and legislation regarding opt‑out and opt‑in for your mailings.
