Support » Plugin: Post SMTP Mailer/Email Log » https:// not being added to linked attachments when email form is sent

  • Shanhua


    Hi Yehuda,

    I use Gravity Forms in WordPress to collect trip reports via a form in our intranet. I use Post SMTP and SendGrid to handle the mail. Colleagues fill out the form and then attach their report file to the form. Several people are then alerted by email that a report has been posted. A link to download the report is in the alert email.

    Recently, I have noticed that sometimes, https:// is not being added to the link in the attached report file — and then people who receive the email alert can’t open the file. Instead, they are brought back to the login page of the intranet site. This does not occur with every instance; only sometimes.

    Also, the form entries go into a Gravity View table on the intranet site. There, all the links are whole and do work properly.

    So I think the problem is happening during the sending process somehow.

    Any idea of how I can resolve this, or point me in the right direction? My Post SMTP details are below, and examples of what the links look like:

    I will try to check and update.

    Did you resolve this? I am having the same problem and I also use along with Sendgrid.

    The links creating by Sendgrid are very long and prior to update would start with https, now they are http.

    and the links also land on my BLOG home and not the correct URL.

    after disabling postman smtp, I have no trouble with the links.

    Hi pwiard,

    It seems to be a two-step process.

    1) You need to “brand your links”. See the first response from SendGrid below for details and a link to instructions.

    2) Then, under “Settings > Tracking” in your SendGrid account, you need to turn “click tracking” OFF.

    That worked for me. The SendGrid team was very helpful.


    Hi there,
    Thank you for reaching Sendgrid support. My name is Alex and it would be my pleasure to assist you.

    I have checked your concern and I would recommend branding your links. Here you can find more details about this process and how you can set it up:

    Please let me know if you need any further assistance.

    Thanks for providing this information! I was able to see that the link does not correctly download the Test file directly from the email! Would you mind answering the following questions so I can see if this is part of an issue affecting other customers as well?

    Which plugin was actually used to create the message? i.e. Woo Commerce, Gravity Forms, Mail Poet, Ninja Forms, etc.

    Are you using a WordPress site?

    Could you please list of any additional plugins installed on your WP integration if you are using WP?

    Have you tried turning click tracking off and making a test send?

    When sending only with WP and SendGrid and click tracking enabled, does this still occur?

    Thank you!

    Thank you @shanhua

    I’m sure it will help a lot of users.

    Thank you. Very much appreciated.

    The SendGrid link has changed after they’ve updated their site.
    For anyone else interested, the correct link is:

    thanks again, already figured that out by searching their support. Set it up and things look like they are working again.

    Take care.
