How do I read the Messages screen?

Open Messages for one row per send attempt, newest first.

Filter messages

1. Open the status filter.
2. Choose All messages, Sent, or Failed.
3. Use the pager to move through the results.

Each row shows the subject, status, recipient, sending mailbox, campaign, and attempt time.

Read a status

Status	Meaning
Sent	Gmail accepted the message and placed it in the sender’s Sent folder
Pending	ColdMerge is still confirming what happened
Bounced	A permanent bounce was received for this message
Failed	Gmail refused the send, or the outcome could not be confirmed safely

A Pending attempt is checked against Gmail’s Sent folder. If ColdMerge finds the message, it becomes Sent. If Gmail proves that no message was sent, it becomes Failed and a campaign can retry once.

If ColdMerge still cannot decide safely after 25 hours, the row becomes Failed and that send is not tried again. This avoids sending a duplicate.

Diagnose a failure

Message or cause	What to do
Gmail rate or quota refusal	Wait. ColdMerge applies Gmail’s backoff before trying again
Mailbox needs reconnecting	Open Settings, then Accounts, and reconnect it
Mailbox credential could not refresh	Reconnect the mailbox under Accounts
Unsubscribe footer did not survive the message markup	Simplify the end of the message body and try again
Interrupted before Gmail accepted it	ColdMerge retries once, then stops rather than risk a duplicate
Sent folder cannot confirm the interrupted send	No action. It is marked Failed and is not sent again

The exact provider reason appears under a failed subject.

Open the message in Gmail

A Sent row has Open in Gmail. Failed and Pending rows do not.

ColdMerge stores the send record but not the message body. Gmail holds the copy you read and reply to.

The same history appears on a contact, limited to that person, and on a campaign, limited to that campaign.
