100% Reading Assurance

Know if your message was read –
for sure

What is it?

Sealero is a technology that promises 100% accuracy in opening rates. Without Sealero knowing that the message was opened – the message cannot be read at all.


Application examples

Many organizations and people must know whether their messages were read or not: from invoices and money-worth vouchers to blood tests results. Sealero gives you 100% opening rate accuracy, no matter what platform the message was sent from: an iPhone, Facebook account or a professional Email Marketing software.
