Transactional Email

What is the difference between transactional, triggered and marketing emails?



What is Email encryption?

Mailthumb attaches great importance to confidentiality and encrypts all connections as much as possible between servers and customer emails (like Gmail):
for incoming connections, we recommend you send your emails through our SMTP using port 465, which uses the SHA256 encryption protocol. for outgoing connections, we always try to use the TLS protocol whenever it is available. If it is not available, we use the insecure standard SMTP protocol.
