You are welcome to request a custom opt-in form from your
Dog Handler at any time. But, if you'd like to try your 
hand at coding your own, here is a simple 10-step guide.

Before you start building the code that you will post on 
your website (that will subsequently gather new subscriber
data automatically in your Mail Dog account), it is a good 
idea to set up the list that the data will be gathered in 
and the confirmation message that will be sent to new 
subscribers.

Step 1:

Go to Lists and name and save your new list that will house
this data (if you have a list already created or simply want
the data to merge into a current list you've uploaded, 
select that list on the page). After saving the new list 
or selecting the existing list note the list's ID number 
(located in the list's URL in the address bar of your 
browser where you see ID= followed by a number). This number 
uniquely identifies this list and will need to be inserted 
into your opt-in code.

(NOTE! Make your list a rich list by checking the 
'create a rich list' box if you plan to gather any data beyond
email address)

Step 2:

Visit Messages and create a placeholder for the custom confirmation
email message that you want new subscribers to receive after they 
have added themselves to your mailing list. After naming and saving
your message note this message's ID number (located in the message's
URL in the address bar of your browser where you see ID= followed
by a number).

(NOTE! You can customize this message later with text and images, for
 now you simply need to name and save it). 
(NOTE! In this unique case the name of your message is viewable to 
recipients, it becomes the subject of your auto-generated confirmation 
email to new subscribers so you will want to choose something like 
"Thank you for subscribing!" or "Welcome to our mailing list!")

Once you have noted the ID numbers of both your list and your message
you are ready to build your code!

The best place to build this opt-in code is in a plain text
environment, use Notepad on a PC or SimpleText on a MAC.

Step 3:

Start by copying and pasting the following block of code, you will
not need to modify anything in the following block:

<FORM METHOD="post" ACTION="http://maildogmanager.com/optin.html"
 TARGET="optin"
 onSubmit="window.open('','optin','resizable=yes,scrollbars=yes,status=no,width=600,height=400, top=10,left=10,screenX=10,screenY=10')">

Step 4:

Enter your list's ID number into the following VALUE field, erasing
ENTER NUMBER HERE and replacing it with your list's ID. Then copy
and paste this line in next:

<INPUT TYPE="hidden" NAME="listid" VALUE="ENTER NUMBER HERE">

Example: 
<INPUT TYPE="hidden" NAME="listid" VALUE="12">

Step 5:

Copy the following line of code in its entirety, you do not need to
modify anything in this line:

<BR>Email:<BR><INPUT TYPE="text" MAXLENGTH=80 SIZE=20 NAME="optin_email">

Next you will need to customize the additional fields you would like
to collect beyond email address (i.e. First Name, Last Name, Mailing
Address, Interests, etc.) You can ask for up to 25 additional fields 
of data. You will want to use a unique field number for each and you
will want to replace the text at the start of the line (i.e. Field
1:) with the information you are requesting as it will be visible to
the user, but the rest of the code inside of the brackets remains
unchanged (NOTE! We show the first five field examples below, but
remember you can use up to 25 total)...

<BR>Field 1:<BR><INPUT TYPE="text" MAXLENGTH=100 SIZE=20 NAME="field_1">
<BR>Field 2:<BR><INPUT TYPE="text" MAXLENGTH=100 SIZE=20 NAME="field_2">
<BR>Field 3:<BR><INPUT TYPE="text" MAXLENGTH=100 SIZE=20 NAME="field_3">
<BR>Field 4:<BR><INPUT TYPE="text" MAXLENGTH=100 SIZE=20 NAME="field_4">
<BR>Field 5:<BR><INPUT TYPE="text" MAXLENGTH=100 SIZE=20 NAME="field_5">
.
.
.
<BR>Field 25:<BR><INPUT TYPE="text" MAXLENGTH=100 SIZE=20 NAME="field_25">

(NOTE! Do not include email as a field as you have already included it in Step 5)

Step 6:

Now you will add the subscribe and unsubscribe radio buttons and the
submit button. Copy and paste the following lines into your code
(nothing needs to be altered here):

<BR>
<BR><INPUT TYPE="radio" NAME="optin_action" VALUE="subscribe"CHECKED> Subscribe
<INPUT TYPE="radio" NAME="optin_action" VALUE="unsubscribe"> Unsubscribe
<br><INPUT TYPE="submit" VALUE="Submit">

Step 7:

Tell your form what account you are by entering your username in
place USERNAME HERE:

<INPUT TYPE="hidden" NAME="client" VALUE="USERNAME HERE">

Step 8:

Add the message ID of the custom confirmation message you set up
earlier to the following line in place of CONFIRMATION MESSAGE ID:

<INPUT TYPE="hidden" NAME="subscribe_confirm" VALUE="CONFIRMATION MESSAGE ID">

Step 9: (NOTE! This is optional)

If you would like to require any of your data fields beyond email
(first name and last name, for example) you will need to add a bit 
of code that gives an error message to the user if these fields are
left blank. For each field number you want to require you will add
the following line:

<INPUT TYPE="hidden" NAME="field_1_required" VALUE="1">

Example: if you wanted to require first name and zip code and you
find that they are field 1 and field 5 in your form, you would add
the following to your opt-in code:

<INPUT TYPE="hidden" NAME="field_1_required" VALUE="1">
<INPUT TYPE="hidden" NAME="field_5_required" VALUE="1">

(NOTE! Skip this step if you do not want to require any fields
besides email, which is required automatically)

Step 10:

End your opt-in form with the following close form tag:

</FORM>

Save your form in a text document and test it by creating an
opt-in form test message in your account, inserting the completed
code into the HTML box on your main messages page and then previewing
the page (fill it in and submit it - your confirmation message should
appear and your data should then populate in your list - if it all
works you're ready to post the opt-in code on your website!)
