Likely, you didn't receive your welcome email because we don't have your details from your employer just yet! Usually, we receive this information within 2 weeks from the day that you receive your payslip.
Not to worry though - if you'd like to opt out of your employer's pension scheme, you have 1 month to do so from the day you receive the welcome email.
It's also possible you didn't receive the welcome email due to a typo in your email address. So, if you haven't received the email yet, it's best to get in touch with us at email@example.com so we can take a look.
