SMTP Error Messages

SMTP Response Codes and Errors

Simple Mail Transfer Protocol (SMTP) is an internet standard for email transmission.
SMTP is a text based protocol in which the sender communicates with the mail receiver by issuing commands and receiving a response code.

Sample:

C: MAIL FROM:
S: 250 Ok

In this sample the client issues the MAIL FROM command and the server replies with 250 Ok.

The following (incomplete) list of response codes and error messages should help finding errors in your mail settings.
It contains common problems and error messages.

SMTP Error 221

221 Service closing transmission channel
221 Closing transmission
221 Goodbye

Error 221 is an authentication error, which means you are using the wrong mail server, the user/password is incorrect, you need to change the authentication method or SMTP access is not enabled for your email account. Try using SSL/TLS if you are sure that the mail server and user/password is correct.

Note: SMTP access in disabled by default on some accounts, e.g. when using Gmail you need to enable «less secure apps» (third party apps) in the Gmail settings: https://support.google.com/accounts/answer/6010255?hl=en

SMTP Error 421

421 Temporary System Problem. Try again later.
421 Try again later, closing connection.
421 Server busy, try again later.

The SMTP error 421 is normally used for temporary problems on the mail server or a problem with the recipients email account.
Some mail providers might also return 421 after you reached a limit (restriction) on your mail account (see SMTP Error 451 below).

SMTP Error 451

451 4.3.0 Mail server temporarily rejected message
451 You have exceeded your messaging limits

If you receive one of the above (or a similar) error message from your mail server (after you’ve sent out some messages), then you have reached a limit on your mail server (or email account). This means your mail server will not accept any further messages until you waited some time.

Your mail account might have one or multiple limitations:

• Daily mail limit, e.g. max. 2000 messages per day
• Hourly mail limit, e.g. max. 500 messages per hour
• Message submission rate limit

Note: No mail software can send more messages as your mail server (or email account) allows. It’s a limitation of the used email account and not a program limit or software bug. Please contact your mail administrator or mail provider for further details on your account limits for SMTP mail (outgoing messages).

If the used email account is too restrictive, use a different email account (and mail server) instead. It’s recommended to use an email account from your own domain (website), your company mail server or a business email account. In general a business account should have less mailing restrictions than a free account.

SMTP Error 530

530 Authentication Required
530 5.7.0 Must issue a STARTTLS command first

Check the authentication (username/password) and enable SSL/TLS (StartTLS) in the account settings of your mail client, if required.
If you are using MailList Controller, change the authentication method to «StartTLS» (Details).

SMTP Error 550

550 Requested action not taken: mailbox unavailable [E.g., mailbox not found, no access]
550 5.7.1 unable to relay for
550 The email account that you tried to reach is disabled
550 Invalid recipient
550 No such user here

You will get this error when you try to send an email to an invalid email address or if you need to authenticate before sending an email.
Some providers also use error 550 to indicate that you reached your send (relay) limit:

550 5.4.5 Daily sending quota exceeded
550 5.7.1 Email quota exceeded
550 5.7.1 Daily SMTP relay limit exceeded for customer

See: «SMTP Error 553» (below) for details.

SMTP Error 553

553 Requested action not taken: mailbox name not allowed
553 Mailbox name invalid

Check the recipient’s email address: either the email address does not exist or there is a syntax error. Also check additional recipients in CC and BCC.

553 Sorry, over your daily relay limit
553 Too many mail
553 Quota exceeded

If you receive one of the above (or a similar) error message from your mail server (after you’ve sent out some messages), then you have reached a limit on your mail server (or email account). This means your mail server will not accept any further messages until you waited some time.

Your mail account might have one or multiple limitations:

• Daily mail limit, e.g. max. 2000 messages per day
• Hourly mail limit, e.g. max. 500 messages per hour
• Message submission rate limit

Note: No mail software can send more messages as your mail server (or email account) allows. It’s a limitation of the used email account and not a program limit or software bug. Please contact your mail administrator or mail provider for further details on your account limits for SMTP mail (outgoing messages).

Why do your mailing lists contain invalid email addresses?

Invalid email addresses on your list may be spam traps.

Spam traps are the email addresses used to catch spam senders. They are usually created by inbox or blacklist providers to maintain the anti-spam policy and healthy mailing lists. If you send emails to spam traps, you risk being blacklisted, since it means that you aren’t practicing good mailing list hygiene. Thus, you can get a spam sender reputation.

How can spam traps occur in your mailing list?

Recycled email addresses

These are real but abandoned email addresses. Internet services deactivate addresses after some period of being inactive. Sometimes, they use them as spam traps to identify spammers.

Pristine email addresses

People never use these emails. They are placed on public websites but hidden in the code. They aim to reveal corrupt practices of email list growing, such as website scraping.

Old and inactive subscribers

Your mailing list may include the same email addresses that you’ve collected at the beginning of your business. That’s why some of them can be unengaged. Sending emails to inactive subscribers means that your emails will bounce.

Misspelled email addresses

People can give you an address with the typos deliberately or unintentionally. In the first case, they may have filled out a form that needed an email but didn’t want to share it. Thus they type anything that comes to their mind. Indeed, such an address will be fake. In the second case, it’s just a misprint. Still, you have to take steps to avoid spam traps.

How to avoid sending emails to spam traps?

Contact inactive subscribers

Send an email to subscribers who have not been active for one year, for example. Just ask if they are still interested in your emails. If not – give them a chance to unsubscribe.

Make use of double opt-in

Double-opt in is an excellent practice for building an email list of interested and engaged subscribers. Using this method, users can express their wish to subscribe via the confirmation email. Thus, you will have fewer subscribers, but the mailing list quality is more important.

Check new email addresses

Use a validation tool to find fake and misspelled email addresses.

Never buy mailing lists

The most obvious advice ever, but it works. A purchased email list is a collection of things that looks like a real email address. Surely, they will never bring you engagement.

Besides, when you add a mailing list to SendPulse, you’ll have to prove that you have permission to email the users. This is how an email service prevents sending spam.

After sending an email campaign with SendPulse, go to «Reports» and check its performance.

In «Error statistics,» you’ll discover the number and type of email delivery errors. They’ll help to:

I see a lot of cases where a developer encounters the error “The email address for the recipient is invalid. The recipient Id follows.”, but isn’t sure what is causing the problem to occur in their code. The error can be a bit misleading, as you would expect the ID of the recipient to be the issue; however, that’s not the case with this error. I want to show you the typical reasons that this error occurs and how to check for it.

Possible causes

Email address missing for a recipient: The most straightforward reason that you may run into this problem is that the email address for one or more recipients in your API call may be missing, so you’re only passing part of the recipient information. It’s worth double-checking each recipient to make sure that all information is being sent correctly.

Incomplete email address: If you’ve checked to make sure that you are passing an email address for all of your recipients, then the issue that you may be encountering is that the email address is incomplete. For example, if you try to pass “john.doe@ example.com”, it will result in the error. At first glance, you may not notice the space between the “@” and “example.com”, but it’s an issue that I’ve seen trip developers up before.

Using a template, but not specifying all roles correctly: When you’re using a template or composite templates and encounter this error, it could be that your API call is encountering either of the above issues, or you could have an empty role that the system is trying to use, but is causing the error to occur because there’s no role name to assign a recipient to. If this is the case, you should ensure that you’re passing the correct roles with the correct recipients assigned to them and that there isn’t an empty role not being used on the template.

Question

I just set up my email account on my device. But, every time I try to send email, it says the email address is invalid, any advice?!!

Answer

NOTE: If you are having problems getting or receiving email, this article might help. If you still are having problems after reading this blog, please contact your email or internet provider as I cannot offer extended advice on this subject. My business focus is web and graphic design — not email.

If you can send an email to another address, the problem is the recipients email address and not your email set up.

Usually, this means something is not quite right with one of your recipient’s email addresses. Sometimes a sender will have their “reply to” email address spelled incorrectly and it ends up in your address book. So, when you try to type in their address it auto-fills with the wrong address. It could be a space or bad character.

Double check the email addresses of the people you are sending to and check for things like:

• Extra space somewhere in the email address. Usually auto-fill is the culprit what looks like your correct email is actually your email with a trailing space you can’t see: [email protected]<space>
• More than one ‘@’ sign
• Username is longer than 300 characters
• You’re entering ‘@gmail’ or ‘@yahoo’ instead of ‘@gmail.com’ or ‘@yahoo.com’
• Their domain name is spelled wrong
• Hand type (not auto-fill) their email address and see if it will send.

If you’ve tried these and still have no luck, try double-checking your own “reply-to” email address, and email address to make sure you have your email spelled properly.
