When my daughter sends an email it delivers multiple times, she was excepting an apprenticeship offer sent an email and ‘replied to all’ we’ve been told that the email is delivering multiple times a day 🤦🏼♀️ we don’t know how to stop it any help as this must be annoying for her employer. Not very tech savvy I’m afraid so n sure in how to stop it apart from potentially asking them to block her 😬 HELP
