Error while sending a campaign

When you are in the campaign list tab you might see something like this, occasionally:

This means that Woodpecker has encountered a problem while attempting to send email from your SMTP server. 

First thing to do in such case is checking whether the account is connected to Woodpecker at all. It might have disconnected due to password change, wrong refresh token etc. Disconnecting email account from Woodpecker and connecting it again might solve some of the issues. 

The error shown in example is somewhat generic, and if you see it we might be able to give you more detailed information after you contact us at support@woodpecker.co.

Other errors that you might see are:


Email blocked due to SPAM problems

This means that sending of your emails was blocked by anti-SPAM filters of your email provider. This does not necessary mean that there is something wrong with your emails, as anti-SPAM filters tend to be rigorous nowadays.

In this case we pause sending campaigns from account in question for 10 to 24 hours.

The best solution would be to contact your email provider and ask why your messages are being blocked.

 It might also be a good idea to check the contents of your emails in services like mail-tester.com or Email On Acid to learn what part of it might be treated as suspicious by various ant-iSPAM mechanisms.

Outgoing quota is exceeded.

This means that you have reached hourly or daily limit of number of emails that are your provider allows to be sent from one address in a given period. For example Gmail allows users to send no more than 500 emails daily from one email address.

Here you might find a summary of limits set by various providers, but it is not complete. It is always best to contact your provider directly to address this issue.

In this case we pause sending campaigns from account in question for 4 to 24 hours.

Error: Sender address blocked

This means that your provider has blocked your address for some reason. Contact them to resolve this issue.

Authentication failed

This is quite common, but not unequivocal. It might mean that you simply changed your email password and forgot to update it in Woodpecker, but it might also mean that your account has been blocked for other reasons. If it is not a problem with credentials then it would be best to contact your email provider.

Error: Couldn't connect to host
