Yes you can install an autoresponder on your Website.
The way it is done is to install a good autoresponder software. It is also linked to the email account that goes along with the website.
When you have your own autoresponder software installed on your website and its email account is included in the setup you can set up as many autoresponders as you want, all with their own series of autoresponder messages that will go out to the subscribers who signed up to the signup form on the different webpages you have placed the signup forms onto.
Each autoresponder will generate its own signup form and have its own series of messages to send out to its subscribers.
Each time you set up a new autoresponder it would just be done on the same website and email account but with a different autoresponder name, such as; ar abc, ar 123, etc.
Or you can set up as many autoresponders that you want to on as many different websites that you have and each of those websites email account. And this can be done over and over as many times as you want.
After you sign in to the control panel for the autoresponder that is installed on a website you can create as many autoresponders as you want by just typing in a name for it and pressing submit and you can keep doing that as many times as you want and have that many different autoresponders.
After you have setup as many autoresponders as you want to, you would just click on the name of the autoresponder on the control panel and then you'll be on the admin control panel for that autoresponder.
That is where you set up the header for your email messages; from name and from email; the redirect site url which is the next page shown after someone signs up to your signup form; there will be a choice for whether to show an unsubscribe link at the bottom of each outgoing email so that your subscribers always have that choice available to them; and there is a link you can press that generates the signup form for you that is linked back to the autoresponder that you are working on.
After someone signs up to that signup form that you can put on any website or webpage they will recieve the first message in the message series.
The messages are also set up right there on the admin control panel page that you are working on.
You can have 1, 2, 3, or as many messages as you want in the message series and there is a setting for how many days their will be between each message. Each message can have a different number of days between it and the previous message and the next message. With some autoresponder software you can also add an attachment to each message.
Each autoresponder you setup can have it's own series of messages to go out when someone signs up to the signup form that is generated for you on the control panel of each autoresponder that you set up.
This way you could have a different set of messages for each websites signups if that's what you wanted.
After you set up the first autoresponder software then it is simple to set up another one because each time you setup a new autoresponder it will be done exactly the same way as the first one.
There are two problems associated with autoresponder software.
The initial cost can be expensive and the software can be complicated and difficult to install.
The more extra features that the autoresponder software has the more it will cost. You can find a full featured autoresponder software without alot of extra features for under $20. You pay for it once and then you own it.
The autoresponder software should be easy to install and easy to work with. It should come with a step-by-step installation and users guide.
It should be able to be installed on as many websites as you want with as many autoresponders on each of those sites as you want so that each autoresponder can send out a different series of messages.
