Actually I would say that everybody who knows how to develop a website knows how to do what you say on top, I for one am not prepared to tell or show anyone who doesn't know how to do it and run the risk of being responsible for one of the most common ways spammers get to know and inunate someone's email address phone number or anything else.
Maybe you should try searching for the answer, there used to be hundreds of websites where one could get that sort of thing just by copying and pasting the code they provided, not sure there are so many around nowadays because of that risk, and that there are better more secure ways to do that ( which I know you have been shown how to do that).

Hi Inger and Wayan,
Sorry - Seems that I should better not try to make websites. I'm no coder and thought, that this "mailto" is a feature I can use in SD without any coding knowledge.
Thought I need not to write my emai adress in clear text.
Thought the pop up "mailto" window with the selection of the mail program can pop up without the visible written email. After selecting the mail program the mal to adress is inserted automatically like the "concern" is inserted...
Sorry for the misunderstanding and greetings
Michael

I just discovered in SD in
Elements > Form Element
the email form mail@
Could this be the SD way for a customer to send his email adress to the webpage owner ?
Could someone describe, what I have to fill in under "Element Properties" (and possibly elsewhere) to make it work ?
Thanks

In the original form that I made for you, I used that form element. However, it is dependent on a PHP back end...

And I made a simple form for you to go in the FOOTER that just needed them to input their email address, which has all the php configurations etc done.

All you had to do with ingers form was change the link to point to the correct php file/folder name.
The form elements in site designer have been available for a long time, certainly since we started helping with your Cuba project, and they still require PHP back end stuff to make it work.
I really believe that the main reason you seem to only get spam emails from the website(s) is that
1/ the bots don't need to see the website to complete things like that, they can see it in the code
2/ human spammers don't really care about what a website is for how it looks functions etc.
Which leaves the final conclusion they possibly other real humans who should be your targets either arent seeing your website(s) or aren't impressed /inspired /enough to consider making an inquiry for whatever reason (I can spot 2 reasons straight away)
I hope that you can fix this issue before too long because I also appreciate the time scales involved for releasing your video samples for distribution considerations.

Hi Michael
In the beginning your question was aimed at you getting ONLY spammy responses from the form (s) on your websites.
Can I ask (just to be clear in my own head) are those spammy emails coming from real human beings, that are completing the forms with stuff that isn't necessarily relevant to your website,, (maybe trying sell you something or provide another service) or from the BOT style spammy stuff (for example like you have inherited millions of euro's and all you have to do is send your bank card details etc etc)

I see that you have tried to make a new layout for the form in the footer of your cubaundercover pages

Hmm
the interesting thing about this problem now is the form on your contact page STILL USES PHP, which you mentioned in your first post stating that PHP didn't work, even with a 'HONEYPOT " capcha type of thingy AND then even if a user selects the link in the ENGLISH version, the page that opens is the GERMAN VERSION of the contact page.

It would surprise me if ANYONE that is human is going to fill out that form (even if they sort of understand German, that is the sort of thing that doesn't help any website which is hoping to attract users that maybe thinking of investing in that website (be it subscribing/purchasing/distributing etc) and even the so called security question code won't stop those new automatic AI intelligent spam bots from sending it, because they can still read the question and the answer. It's not a good user experience (very important for Google rankings, and portrays it as an UNPROFESSIONAL Impression ) The best solution would be to put a TRUE honeypot type of JS code in the correct place and add a dummy field that only bots can see.

Hi Inger aand Wayan and thanks for your comments.
Wayan - I don't know if the spams ar human or what they want - but they are sent automatically and repeatedly and have nothing to do with interst in my page. Inger, yes I tried first your form and spam arrived. Wayan, yes I tried your form and there were problems. Then I tried to modify the form myself and spam started to nerv my website provider...
And meanwhile I think it s better to have no form than to loose so much time with it. Sorry for the time I robbed you.

Well Michael you haven't wasted anybody's time except perhaps your own. The form I did for you (the one in the footer) did (and still does work) actually it's still up there on the testing site I did for you, but for some reason it seemed that it wasn't what you wanted. (possibly because it used Google Recapcha (optional security measure) but that along with a true honeypot type of capture (where only automatic spam bots can see two hidden fields).
Not exactly sure why, but the one one your domain it definitely isn't the one I did.

The form I couldn't get working for you was the one on the contact page. which is why Inger stepped in to help out and got it working. (but that one doesn't use ANY TYPE of Captcha (even though you suggested it has a honeypot CAPTCHA, method,,the reason being you haven't activated it in the PHP file which leaves it wide open to Automatic Spam emails.

Regardless of if they are real humans or automatic bots, they will have already your email address which you put on the form, so not having a form may not stop the spam stuff from coming. Not having a form at all definitely will mean that anyone that is interested WILL NOT be able to contact you, which sort of defeats the whole point of having a website, to promote your documentary films, you may as well just put the film up on YouTube or some other video platform, and promote it on that.
