Email delivery issues

You sent an email batch, but bounces are high, opens are unusually low, or recipients say nothing arrived. Start by understanding which of three distinct problems you have, then work through the causes below in order.

Bounces, blocks, and spam placement#

These look similar in results but have different fixes:

• Bounces — the receiving server rejected the message and returned an error. Bad or dead addresses are the classic cause. Bounces show up in the batch drilldown's bounce count.
• Blocks — the receiving server refuses or silently drops your mail, often because of sender reputation. Blocks may not produce a clear error, so they can look like messages that simply vanished.
• Spam-folder placement — the message was delivered, just not to the inbox. It won't appear as a bounce; the symptom is a batch with normal delivery but very low opens.

Where to check: open the batch drilldown for opens and bounces, review Settings → Deliverability, and confirm your account status in Settings → Email accounts.

Common causes#

Your email account is unverified or misconfigured#

Sending needs a connected, verified email account. Open Settings → Email accounts and confirm the account you're sending from is connected and verified. If you haven't finished setup, see Configure email.

Poor list quality#

Old or unverified addresses drive bounces, and sustained bounces damage your sending reputation, which then causes blocks. Verify addresses before you send — see Verify email addresses. Verification runs domain checks on every address and costs 1 credit per 10 addresses. If a batch already bounced heavily, verify the list before you send again.

Missing address in your signature#

Commercial email is generally expected to carry a sender mailing address, and mail without one is more likely to be filtered. Landing Zone signatures have a structured address field — fill it in under Settings → Email accounts. See Email signatures.

Spammy content or spin overuse#

Templates support spin syntax to vary your message, but heavy spin that produces awkward variants — or pushy, spam-associated wording — makes filters suspicious. Review the template in Templates, read a few generated variants in the preview, and simplify.

Volume spikes#

A sudden jump in sending volume looks like a compromised or spamming account to receiving servers. Increase volume gradually and watch each batch's opens and bounces in the drilldown before scaling up.
