It gets connected to the database but not updating the database. I think I'm having trouble with 'addTracking' method. Any kind of help will be appreciated. Thank you.

same issue

[dunawayk]

I have the same issue. Have you found a solution?

[mryraghi]

Hi guys, I got it solved by adding an await in front of addTracking:

let newmsg = await pxlForEmails.addTracking(msg, {recipient: "[email protected]"});

var mailOptions = {
    from: '[email protected]',
    to: '[email protected]',
    subject: 'Do you need a professional Website for your business?',
    html: newmsg
};
...

Even after adding await, I still get the error TypeError: this.options.pxl.createPxl is not a function. Any suggestions ?

@BasselFouad I assume your setup is not correct. Please check the Usage section in the readme again. Your error seems to be caused by passing something incorrect as the pxl parameter to the PxlForEmails constructor.

[BasselFouad]

Yes thank you I have now fixed my error and am successfully sending emails. However, nothing is happening in my database in terms of tracking the sent emails, my email markup is a string of html, and I am then using this : html = await pxlForEmails.addTracking(html,{ recipient: req.body.recipients[i].email }) It is worth noting that my clicks on buttons are redirecting correctly.

@BasselFouad Please double check the Usage section in the readme to verify that you did all setup steps. For starters, check that your emails contain the pxl=... additions and that external links are shortened. If you face further hurdles, please open a separate issue for that since this doesn’t belong into this issue here anymore. Thanks!
