No, if you have received the blacklist notification, you are not blocked from sending mail.  You can continue to mail while you work through the remediation steps. The only time we will ever block you from sending mail is if you trigger a listing at Spamhaus, the world’s most respected and widely used blacklist. If this happens, you will receive a call or email to let you know what’s going on and we will work with you to resolve the issue. This is a rare occurrence.

When a customer triggers a blacklisting on Marketo's shared IP range that customer is moved to a set of IPs we call the quarantined IP range.  We do this to protect the health of our shared network and ensure the best deliverability possible for all of our customers on that network.   If you have received a Blacklist Notification from Marketo reporting that you have triggered a blacklisting your Marketo account is now in the quarantined IP range.   While you are in the quarantined range it is possible that you may experience a slight decrease in your deliverability rates. The reason for this is that you are now sending from a range made up of senders that have also caused other blacklist issues. All customers have received a notice of the listing and are in the process of repairing their database.   There are two ways to be removed from the quarantined IP range: Follow the steps outlined in our Blacklist Remediation article.  Be sure to fill out the form referenced in the email alert to indicate that you have taken steps to mitigate the issue. Demonstrate clean sending behavior for 3 months. We remove senders from the quarantined IP range if they have not triggered any new listings in 3 months.   To ensure your best deliverability rates blacklist issues should be addressed right away to prevent further damage to your sending reputation.   Furthermore, if no action is taken to improve list hygiene the issue will likely recur. Marketo's Privacy Team strongly recommend following the Blacklist Remediation steps.   Additional Resources: Blacklist Deep Dive

  Quick points: *Spamtraps are addresses owned by antispam organizations *Emailing a spamtrap (usually) gets your IP or domain blacklisted *Maintain current, direct opt-in with an active lead database to avoid this     What is a spam trap or spamtrap?   A spam trap, or spamtrap is an email address secretly owned by an antispam organization that is used to detect spam. Antispam organizations do not sign up for mailing lists, so they consider any email sent to these addresses to be spam. Once email is sent to the spamtrap, the antispam organization that owns this address will blacklist the IP that sent the email (or, less often, domains that are linked in the message).   Email administrators purchase subscriptions to various blacklists, and use the lists to block all incoming email from listed IPs or containing listed domains. From the marketer’s perspective, this can mean a high number of bounced emails leading to low lead engagement, and ultimately to weak revenue performance.   There are two types of spamtraps – pristine traps, and repurposed/recycled traps. A pristine trap is an email address that was never used by a person. A repurposed trap is an email address that once belonged to someone but is no longer a valid address; these addresses will bounce as bad addresses for at least six months before an antispam organization will turn them into live traps.<   How can a spamtrap get into my Marketo lead database?   Purchased data   Purchased data is unreliable. The antispam world does not like the use of purchased data so antispam administrators have made a concerted effort to get spamtrap addresses into the databases of data vendors. While data vendors may say they provide opt-in data in reality consent should be direct to your company./p> Sending unsolicited email is prohibited by the Marketo Terms of Use because this practice has a high risk of causing blacklist issues that can destroy deliverability for multiple Marketo customers. To avoid spam traps get direct opt-in before sending email. If you have purchased data in the past we recommend setting any inactive purchased leads to marketing suspended or simply removing them from your database. Old data Repurposed traps are email addresses that were once valid but are now owned by an antispam organization. This can happen when a company goes out of business; expired domains are often purchased by antispam organizations. Sometimes a company that has a direct partnership with an antispam organization will allow email addresses of former employees or users to become spamtraps. Because antispam organizations will generally make sure future spam traps return a bounce as bad addresses for at least six months before they become spam traps you can prevent repurposed traps in your database by emailing remaining engaged with everyone in your database at least once every six months. Avoid “wake the dead” campaigns to addresses you have not contacted in more than six months. Unconfirmed form entries People can unintentionally enter spamtrap addresses into forms either by making a typo or by intentionally using a fake email address that happens to be a spamtrap. If you use single opt-in, you may add spamtraps to your mailing list. This is more likely to happen if you are a B2C company or if someone thinks they can get whitepapers or free trials simply by filling out a form with made-up information.   How can I identify spamtrap addresses?   Spamtrap addresses are considered trade secrets by the antispam organizations. They do not share these addresses because their goal is for senders to change their mailing practices rather than to simply remove spamtraps from their mailing lists.   That said, one thing we do know about spamtraps is that they tend to be automated processes and do not engage. Spamtraps do not click links. You can use smart list filters to identify inactive leads in Marketo.   How can I prevent spamtraps in my database? Maintain active, direct opt-in for all leads. Don’t purchase data. (To grow your list, sponsor events, use list rental services that send the first message for you, or use co-branded content that sends you only good leads) Email everyone you want to email at least once every six months Don’t add old data directly to your mailing list. (If you need to, add in small batches and send a welcome email with a slightly different subject to each batch.) Regularly clean your database of inactive leads Grant access to assets such as free trials and whitepapers as email links to discourage intentional use of fake email addresses on forms Use scripting on your forms to identify potential typos

When using Marketo it is not a requirement to set up DNS text records for SPF and DKIM.  However, Marketo recommends setting up SPF and DKIM because it improves the deliverability of your mailings.  Configuring and implementing one or both of these records is a way to verify that the server sending your mail is authorized to do so.   If a recipient domain is configured to check for SPF and/or DKIM and those DNS records are available and your mail passes the SPF/DKIM check, it further reinforces its good reputation.  Not implementing SPF/DKIM records does not add to or subtract from its reputation, it’s just not there.   Please note, not all domains check for SPF/DKIM and if this is the case, again, the presence of these records does not add or subtract from your mail’s deliverability. There is no negative effect to setting up these records, and it can improve your deliverability.  It is for these reasons that Marketo recommends setting up these DNS records and configuring their use in your instance of Marketo.   For more information on how to set up and configure SPF/DKIM, please read our KB article here.

Issue Emails with valid email address get soft bounced with this error:  Local address contains control or whitespace. Solution This error means that the email has a space somewhere in the the From email address or there was a comma or extra character in the From line.  If you do not see a space inside the email address, check the end of the address to see if a space somehow got added at the end. The email send did not occur due to the error with the address. The emails will need to be resent once after the associated address is corrected with white spaces or extra characters. Also, there is the possibility that email address "text" contains Paragraph marks or hidden formatting symbols (https://www.computerhope.com/jargon/f/formmark.htm) and instance users will required to have it reviewed and changed.

Issue You want to recall emails sent from your Marketo instance. Solution Once an email has been sent from Marketo Servers it cannot be recalled or pulled back. You can cancel a program before it sends at its scheduled time using the steps here: https://docs.marketo.com/display/public/DOCS/Abort+Email+Program The above cancellation only works on Email Programs. If you are wanting to cancel a smart campaign follow these instructions: https://docs.marketo.com/display/public/DOCS/Abort+a+Smart+Campaign Note: A smart campaign will only stop what hasn't been run yet. If you already had 100 emails sent by the time you cancel it, those 100 emails cannot be unsent. You may see in your Outlook an option for "Recall Email." This function within Outlook only works with internal sends/private systems where the client can request the server revoke access to other client mailboxes before they're viewed, such as your office email to other users in the same company.

When someone emails abuse@marketo.com to tell Marketo that they received unsolicited email from one of our customers, the result is called an abuse report.  Instead of just hitting the “Report Spam” button, someone actually took the time to write to our abuse@marketo.com address and explain to us that they never wanted email from the sender.  Because of this direct complaint we take these types of spam reports very seriously. Only about 10% of our customers ever receive any abuse reports at all so it is cause for investigation if you receive one. If you receive notification that someone filed an abuse report against your account review your list management practices. Below are some things to consider: When people sign up to receive emails from you, is it made clear to them that they are giving you permission to email them? Have you recently added any new leads or lead sources? Have you recently added older leads to your database that you have not reached out to in the past 6 months or more? Was there anything about the campaign that was complained about that makes it different from previous campaigns?   In most cases people file these kinds of reports because: They never requested to be on your email list. They did request to be on your email list at some point but have forgotten because they have not heard from you in so long.   The importance of using explicit opt-in in your list building efforts cannot be stressed enough. You should also send to active leads consistently enough that they continue to expect emails from you. The best ways to avoid complaint driven reputation issues is to send to opted-in, engaged recipients. To help with this, a lot of senders clear out their inactive leads every 6 months or so. An inactive lead is a contact that has taken no action in the given time period— they haven't opened an email, clicked a link, visited your webpage, attended a Webinar, and so forth. Inactive leads are a dangerous group to continue mailing to because their behavior proves that they do not want to interact with your mail and will likely complain to Marketo or to their ISPs about it. We have a great resource on how to create a Smart List to remove inactive leads here. If you still need some help, please feel free to reach out to our Support team (support@marketo.com).

Issue You see a soft bounce on a lead and in the details you see it show System send failure: Reply-To address parse error (value of the address) Solution Confirm the tokens you are using are for the proper field and that the value for the field is an email address. The parse error occurs when we cannot generate or create a proper email address in the From Email or the Reply To Email fields. The error will show in the parenthesis the value we tried to put in.. For example Service Department is in the parenthesis, this would be an example of a incorrect field being used.

Any emails being sent as part of 'Forward to Friend' will create that user as a new lead (provided that the lead does not already exist in Marketo). When leads are created in Marketo via the 'Forward to Friend' feature, Marketo automatically unsubscribes the lead records in order to protect our global customers from anti-spam laws. This is because a lead being sent a forwarded email doesn't qualify as opting in to a mailing list and also prevents them from getting any other emails by accident.

Issue How to re-subscribe records who are already unsubscribed.     Solution Once the person is willing to resubscribe to receive your emails, either of the following can be done: Smart Campaign: Change Data Value of "unsubscribed" to false.You can either use a Smart Campaign to execute this flow or can just go with single flow action ( select the lead, Person actions > Marketing > Change Data value; Attribute: Unsubscribed, New Value: False.) You can manually change unsubscribe from True to False. To do this, go to Lead database, click on the lead ( whom you need to unsubscribe), go to lead Info tab, look for unsubscribe field , remove the tick or check off the unsubscribe field checkbox.

Issue Issue Description An email was sent to leads but immediately returned an 'Email Bounced Soft' Activity Type with the Activity Details stating: 'Details: Empty address: []'   Solution Issue Resolution This is due to a token used in the 'From Address' Field in the Email editor that does not have a valid value or valid default value. For example: {{lead.Partner Email:default=edit me}} The Record's field value for 'Partner Email' is Empty. As there is no value for the record the token would use the default value 'edit me' which is not a valid value. A valid value must be an email string format such as mark@eto.com
