First and foremost thing for any offer letter or email that comes to you should be the address of the sender (in the case where you are not given the physical letter face to face). For wellsfargo, you can verify if the sender email have u2018@wellsfargo.comu2022 or not.The second thing will be when you open the offer letter verify the Original Wells Fargo logo and also the contact and other details (though these all things can be easily duplicated incase anybody wants to).Apart from this make sure you didn't get the offer letter as an attachment rather it should be a link to open and read the detailed offer letter. When you click the link it should redirect to u2018trm.brassing.comu2022 and that's is where you ll get the original offer letter with your name mentioned and salary break up and all terms and conditions.Just keep in mind that the first point is the most important point as it is difficult to send a mail from the domain of wells Fargo. Thank you
