Email testing & diagnostics

Before running a live sequence, verify your mailbox can actually
send + receive. FlowMaticX ships built-in diagnostics so you don't
need a separate tool.

1. Open Deliverability → Mailboxes.
2. Click the Test button next to the mailbox.
3. The dialog will report:

• SMTP send — can we open a TLS connection and hand off a test message?
• IMAP fetch — can we read the sent folder and confirm delivery?
• Authentication — does the provider accept the credentials?

Typical failures and fixes:

• "Connection timeout" — a firewall is blocking the port. For SMTP,

open 587 (STARTTLS) or 465 (SSL). For IMAP, open 993.

• "Authentication failed" — regenerate the app password on the

provider's side. Gmail requires a real App Password, not your
login password.

• "Relay denied" — your provider requires the From header to

match the authenticated username. Don't mask the sender.

Open Deliverability → DNS check, paste your sending domain, and
review the three records. Green means your authentication passes;
red means mailbox providers will route you to spam.

If any record is missing:

1. Copy the suggested DNS value from the check.
2. Add it as a TXT record at your DNS provider.
3. Wait 5–30 min for propagation, then re-run the check.

1. Create a sequence with your real copy.
2. Enroll just yourself (or a friendly internal address).
3. Watch the inbox — does the message land in Primary, Promotions,

or Spam?

1. If it lands in Spam, pause before sending to real leads and

check your DKIM/SPF first.

Every bounce is logged to Deliverability → Bounce log. Common
categories:

• hard bounce (550) — address doesn't exist. FlowMaticX auto-

suppresses the address so you don't burn it again.

• soft bounce (4xx) — temporary (mailbox full, greylisting).

Retry tomorrow.

• spam complaint (FBL) — recipient clicked "Report spam". We

auto-suppress globally.

If you see >2% bounces, pause and rebuild your list. Apollo-verified
leads typically bounce under 1%.
