Watch out for this fake blockchain email:
The actual link: https://u40257556.ct.sendgrid.net/wf/open?upn=HvOKSqJFA55zs9Q8-2B7p4-2F... is to take you through to a call on WhatsApp with the number 07360458207 which does not accept incoming calls from a normal phone.
Presumably the whatsapp message will try and defraud you by getting your blockchain details so do not connect with them.
