For your first email, do not include any links. If possible, try to send an open ended email. Example, hi, I have just changed my email address to [email protected], you can reach out to me from this address.

Once curious users open and reply to your email, you can then inbox. Target to send to those that open your email and send your offers.

the problem that the emails are lending in spam folder which that the users will not pay attention for it and they will not read it or reply
