Gecko uses a number of message status to let you know what's happening at every turn with your communications.

We've put together a handy list to describe exactly what you should read into each status when you see it:
Processing - your email/SMS is being processed by Gecko and be sent shortly.
Sending - your email/SMS message is being processed by AWS/ Twilio and will be sent shortly.
Sent - Twilio has had a request for the SMS to be sent by the nearest 'upstream carrier' accepted.
Delivered - Gecko has received confirmation from the recipients' email client/ telephone provider that the message has been successfully delivered.
Hard Bounce - your email hasn't been delivered, and has been permanently rejected by the mail server. This could be due to the mailbox not existing, for example.
Soft Bounce - this is a temporary status. Your email has been rejected for a range of reasons, eg. the recipients mailbox being full.
Dropped - your email hasn't been sent, as we have dropped it due to the email addressing having a hard bounce within the last few months.
Opened - your email message has been opened by the recipient. (note: some email clients send a false-positive status back to Gecko. As a result, a small percentage of messages with this message may not be accurate.)
Clicked - the recipient of your email has clicked a link contained in your message template.
Duplicate - multiple messages have been sent to this contact in too short a space of time and Gecko has flagged this message as a duplicate. Messages with this status will not have been received by the recipient. If testing a workflow, this status can be avoided by enabling Test Mode.
Failed - the SMS message has failed to deliver. This may be due to an invalid telephone number, network outages, recipient account suspension, account overflow etc.
No Consent - your message has not sent due to the contact not having consented to receive this type of message. This status can be avoided in a number of ways, including toggling to Ignore Consent Reasons when sending your message.
Sender not Verified - your message has failed as the sender (the email address you're using to send your message) is yet to be verified.
