Mail settings

Here you can configure all about your sending method: sender information, mail server and technical format of your emails.

Default sender information

You can set the default information AcyMailing will use when sending an email. When installing, AcyMailing will get information from your website to preset these data.

  • From name: Default "From Name" used in all your campaigns

  • From email: Default "From Email" used in all your campaigns

  • You can choose to use the same values for the reply-to (enabled by default). If disabled, the next options will be displayed so you can set them.

  • Reply-to name: Default "Reply To Name" used in all your campaigns

  • Reply-to email: Default "Reply To Email" used in all your campaigns. If your receivers reply to your emails, their response will be sent to this address.

  • Add names: If this option is turned ON, the sender and receiver name will appear in the sender/receiver information. If this option is turned OFF, only the e-mail address will be visible.

You can add several reply-to addresses by separating them with a coma and no spaces: user1@example.com,user2@otherdomain.com

You can modify the sender and reply-to properties for each campaign you send.

Mail settings

There are several ways to send emails from AcyMailing. You can choose to send from your own server or to connect to an external delivery service (SMTP).

We recommend the PHP Mail Function but in some cases you might want to use an external SMTP Server (you can even use your own GMail account!). SMTP will be a little bit slower but you might decrease your spam score by using it.

Own mail server
External server

SMTP configuration

  • Server : Address of the SMTP Server. Example : smtp.gmail.com

  • Port : Port used to connect to your SMTP Server. Leave this field empty if you don't know which port you should use. (GMail does use the port 465 because it's an SSL method)

  • Secure Method : Should AcyMailing use an SMTP Secure Connection? For GMail, you should select SSL. This option should only be used if your SMTP server uses a secured sending method.

  • Keep Alive : Should AcyMailing keep your SMTP Connection opened during the send Process? We recommend to turn ON this option. This option should be turned OFF only if you have problems. If you turn it OFF, AcyMailing will connect to your SMTP server, then send one e-mail and then close the connection. It will need reopen the connection with your SMTP server to send another e-mail so it may consume a lot of time whereas if you turn this option ON, AcyMailing will open the connection with the SMTP server once, send the whole batch of e-mails and then close the connection.

  • Authentication : If you enter a Username and a Password to connect to your SMTP Server, please turn ON this option.

  • Username : Username used to connect to your SMTP Server.

  • Password : Password used to connect to your SMTP Server.

Test your SMTP ports

Since some hosting companies block SMTP connexions to external servers, we added a quick test so you can easily see the ports opened on your server and the blocked ones...

Just click on the "What port can I use from my website?" link to trigger that test and Acy will display a list of most used ports blocked or opened.

A blocked port may be blocked by your own server or by a firewall within your host.

If none of your ports are opened and your host does not want to open any, then you can still use our REST API integration with ElasticEmail.

Advanced configuration

  • Encoding Format : Encoding format used for all your Newsletters. We recommend 8-Bit to reduce the spam score.

  • Charset : Charset used for all your Newsletters. We recommend UTF-8 if you send english or international e-mails. We recommend to use the charset used in your country if your business is local.

  • Word Wrapping : Some servers do not allow you to send e-mails with more than xx characters per line. This parameter enables you to set this limitation.

  • Use https urls : AcyMailing will automatically convert your relative urls into absolute ones. You can configure Acy to use httpS urls or standard http ones. If you turn ON this option, you should make sure your website has an SSL certificate and is able to display httpS links!

  • Embed Images : Should AcyMailing embed your pictures inside the Newsletter? If so, the send process will take more time but the recipient won't have to download the picture from your website in order to display it. By default, this option is set to NO so the pictures included in your Newsletter will stay on your own website.

  • Embed Attachments : Should AcyMailing embed your attachments inside the Newsletter? If not, AcyMailing will add a list of attachments with a link to your website in order to download it. If you disable this option, the send process will be much faster as AcyMailing won't send the attachment but a simple link.

  • Send Multiple Part : Should AcyMailing send multiple part e-mails? If so, AcyMailing will send the text and the html version in the e-mail so that depending on the recipient server, the appropriate version will be opened.

  • DKIM : AcyMailing is able to sign your messages based on the DKIM protocol.
