    Hi thanks for such a great plugin.

    Recently users of my site have reported that they can’t subscribe and are getting message saying their email address is invalid.

    I thought they made mistake somewhere (like a blank space or missing @ ), but I tried myself and it appears that the form refuse to accept emails most often, but sometimes it does accept. I tried using firefox and chrome: the behavior is the same and I can’t figure out why it does work sometimes and not at other times :-/

    Any idea what could go wrong ?

    Hi thanks for such a great plugin.

    You are welcome 🙂

    Recently users of my site have reported that they can’t subscribe and are getting message saying their email address is invalid.

    – Is it a single site or multi site setup?
    – Do you observe any pattern between the email address which are accepted and rejected?

    It’s a single site.

    No I didn’t found any pattern. The same address got rejected a few times, then in another trial it got through.

    I thought it was linked with fact of filling the “name” field with incorrect characters but actually this also didn’t seem to make a difference in the end.

    Thank you for sharing your views.

    Can you please temporarily de-activate all other plugins except Email Subscribers and switch your current theme to default WordPress theme and check if it works.

    If yes, keep activating other plugins one-by-one and theme at the end to find conflicting plugin.

    Let me know your views.


    My website is also having the same issue as reported by Lilian Ricaud.
    My plugin version is 3.5.4

    Please help!!!

    Hi winnyapril,

    Did you try the steps mention above?
    Have you installed any spam protection field on your site?
    if yes, then can you just try it with disabling it.

    Hi winnyapril,

    Any update on this?

    Is this issue resolved?

    sorry I couldn’t work on the site for some time.

    I moved my site to another webhost without changing any settings so far it seems to be working. The new wordpress updates came in (wp 4.9.8) so I’m not sure if this helped or if it was linked to the host.

    I’ll keep watching and let you know if the bug comes back.

    thanks !

    Hello Lilian,

    Thanks for the update.

    Feel free to contact us if you will have any issue. We will be glad to help you.

    Ok, so it turns out that there is another bug even after wp updates.

    When I put an email in the subscription form I get the confirmation message “Your subscription was successful! Kindly check your mailbox and confirm your subscription. If you don’t see the email within a few minutes, check the spam/junk folder.”

    so on the surface it seems fine.

    but when I use wp mail log to work out if the mails are sent and it seems the confirmation mails are not sent, the plugin tells me:

    error “could not instantiate mail function”

    I tried disconnecting all the plugins apart from WP Mail log but !i get the same result.

    any idea what goes wrong ? cheers

    Hi guys!

    I have similar problem with plugin and it looks like problem is caused by page caching and nonce expiring for non-logged users. Have used quick fix for es_view_subscriber_ins patching, but need a better solution


    I discovered that I was having same problem, I had error “Invalid e-mail” which switch to nothing happening after updating plugin. Only thing I have done recently was making my site more secure with SSL sertificates (did it like my website host instructed).
    This plugin not working is very big inconvenience and since I’m not a web developer, I have also hard time fixing it on my own.

    Hi Lacebycr,

    Can you please contact us via this link?
    Give us the website URL where you have set Email Subscribers form.
    We will check and let you know.

    Hi there

    I still have a “could not instantiate mail function” error and can’t figure out what goes wrong.

    It only seems to happen when this plugin sents email (whether for new article or for subscription confirmation), but other wordpress email alerts seems to work fine (as seen using WP mail log)

    Hello Lilian,

    It seems you are trying to send a PHP Mail..and PHP mail function is not able to send an email from your installation..

    Please send an email using WP HTML MAIL / WP PLAINTEXT MAIL.

    You can set this settings in Email Subscribers > Settings > Email Type option.

    Hope that helps.

    Please check and let us know how it goes



    I was having the exact same problem as Lilian and lacebycr, and also just updated my site to use and force SSL.

    I found that my problem was that somehow the WP Mail plugin was no longer enabled for some reason. When I re-enabled it, everything worked fine.
