My emails land in spam or don't arrive

I can't send: "Configuration required to send emails" appears

That notice means something mandatory is missing before sending:

• Domain not configured — go to Settings > Branding, Email Domain tab, and verify your domain. See Configure your sending domain.
• No postal address — bulk sends require it by law; add it in that same Email Domain tab.

Until you resolve both, campaigns stay blocked on purpose, so as not to damage your reputation.

I can't send: "You've reached the monthly limit"

Each plan includes a monthly send quota. If you reach it, sends stay paused until the following month or until you upgrade your plan. The notice says something like "You've reached your plan's limit". See Plans and pricing.

The emails go out but land in spam

If you send but they end up in the junk folder, check:

• Unverified domain — it's the number-one cause. A verified own domain is what most improves delivery. See Configure your sending domain.
• Reputation from a dirty list — sending to addresses that bounce or to someone who unsubscribed marks you as spam. Keep your Suppressions clean. See Measure your sends and keep your list healthy.
• Content that triggers filters — subjects in all caps, excess punctuation, a single giant link, or heavy attachments. Write naturally, like a real email.

A specific contact didn't receive the campaign

Look for them in Suppressions: if they unsubscribed or their address bounced, they don't receive sends. It's the expected behavior. Review the detail in Measure your sends and keep your list healthy.

How to prevent spam before it happens

• Verify your domain before the first send.
• Send to audiences that asked to hear from you; avoid purchased lists.
• Segment and send relevant content: fewer unsubscribes, better reputation.
