we have 400 to 500 hundred emails, when we concatenate them and put them in mailto: it does not work, browser automatically adds "..." in between emails and clicking link does not work.

```
<a href='mailto:one@email.com,two@email.com....400@email.com'>open emails</a>

```

Is there a maximum length on **mailto:** attribute ? is there any other way i can open multiple emails ?
