Most of your work will be done from the Campaigns page. Once you begin creating and launching campaigns, they'll appear listed on this page in alphabetical order. Active, Paused, or Archived status (archived campaigns are moved to the bottom of the list) are also shown, along with the date Last Mailed.

At the top you'll see the Total Spend, Total Mailed, CPA, ROAS, and Total Revenue across all campaigns. The Reporting Window for these metrics can be adjusted using the calendar tool in the top right. The Columns tool allows you to select which reporting metrics you'd like to view across all campaigns.

Click the New Campaign button in the top right to create a new campaign, or click into an existing campaign to see the Overview, Creative, One Time Sends, Suppressions, and History tabs.

Create a New Campaign

If your Poplar account is brand new, the only thing you'll see on the Campaign's page is the option to Create New Campaign. Click this button to begin:

Campaign Name & Description

The campaign name should be unique and reflect your use case - adding the date of creation is recommended, if you plan on having multiple campaigns of the same nature.

The description should contain any key information such as trigger filters, notes on audience suppression, or anything relevant worth communicating to team members.

Address Enrichment

Poplar's Address Enrichment feature matches email addresses to physical addresses. If plan on passing email addresses via trigger or uploading a CSV list of emails to be matched, Enable Address Enrichment when your campaign is created, or Edit and existing campaign to adjust the setting. If you already have full address data for you target audience, leave this setting Disabled.

Typically, Poplar's address enrichment process sees a 60-80%+ match rate. In our internal tests we have generally found that older demographics tend to yield a higher match rate than younger ones. Thanks to the strict accuracy filters we've put in place, there should be a high yield of accurately matched addresses.

Running the match process costs an extra $0.07 per piece. You will only be charged if an append is successful, and will not be charged if a match can't be found. Under the campaign's History tab, the system will return append failed if it is unable to identify an address to match. If it's successful it'll change the status to mailing_queued.

Rules and Limitations

  • You must agree to the Share Local Media Supplemental Terms of Use.

  • Emails submitted must be customer emails; you should NOT submit emails you have obtained in other ways.

  • The emails must belong to US residents only.

  • Recipient addresses for append will always be addressed to "Current Resident." Any personalization of the mail piece should not include any PII (personally identifiable information) for that specific customer.

  • Use of certain merge tags in creative design is restricted for recipient privacy purposes.

Matched address data is not available for download and will be redacted from CSV mailing records downloaded from the campaign's History tab. The email addresses that found a match will be visible for tracking and attribution reports.


Enable a specified holdout percentage to compare conversions between mailed and unmailed groups and easily analyze incremental lift. Given that mailings are triggered or launched individually and in real time, the holdout percentage is approximate. The holdout percentage you set is just the odds that any individual mailing will move to the holdout group.

We strongly recommend taking a holdout for campaigns sending at least ~5,000 pieces per month. If you're mailing at lower volumes, the holdout size is generally too small to get a high level of confidence in it, in which case this setting can be left Disabled.

We do not recommend manually taking a holdout from your audience segment. It is best practice to set a holdout inside the platform to ensure the highest level of randomization, and allow for in-platform reporting of lift metrics.

Holdouts are taken after Address Enrichment so matched addresses can be checked against your opt out list. Any holdout requests are still charged for address enrichment, but the base print and mail fee is not charged when the mailing is in the holdout group.


For triggered campaigns, you have the option to specify a daily and/or weekly budget cap. Budget caps are approximate and your actual costs may end up lower or higher.

The reason for this is because you are only charged after specific events occur in the mailing stream. This means if more data appends succeed than expected, or if more mailing addresses you've provided fail to validate, you may see the actual costs come in above or below your budget.



Daily Budget

Resets everyday at 12:00am UTC

Weekly Budget

Resets every Sunday at 12:00am UTC

Budget settings are ignored for One Time Sends. The cost of the send will be charged to your account credits, and the card on file if the balance exceeds your account credits.

Address Strictness

Address Strictness can be set on a campaign-level, which will override the global strictness set under Account Settings. Varying rules are applied when uploading address data and when sending mailings to gauge the highest possible deliverability.



Organization Default

Uses the strictness specified under Account Settings.


Only allows addresses deemed "in-service" by the USPS.


Checks the existence of an address and verifies that the street and unit information is correct.


Will mail regardless of address validity. This setting is only recommended when mailing to commercial addresses.


You can set a custom attribution window when you create a new campaign. By default, Poplar uses a 90-day attribution window. This is the period of time for which you wish to credit a customer's transaction to the mailing. We recommend a minimum of 30 days to see the full scope of your results.

If you're sharing transactional data with Poplar, you may begin to see some results before your attribution window has fully passed. Since these number are considered incomplete, we suggest waiting until the attribution window has fully passed before evaluating the performance of your campaign.

National Change of Address Forwarding

NCOA is a dataset of change-of-addresses filed by individuals and/or businesses with the USPS. The database is maintained by the USPS and we are required by the USPS run a check for every mail piece we send. Learn more.

How is NCOA accounted for when using Geolocations, Geofences, and Zip & State suppressions?

Our location and area-based checks are performed on the original address that you provide. These checks are run prior to NCOA, meaning if your recipient has moved, we do not account for the move in our checks.

However, if you are concerned about potentially mailing someone who has moved outside your delivery area(s), you can append the phrase "or Current Resident" to your recipient name field. This allows you to skip NCOA, meaning your mailer ultimately lands at the original address.

Here's an example:

Return Address (Optional)

Some campaign use cases require or would benefit from the option to show a unique return address from the one listed for your Organization. Reach out to to have this feature turned on for your account.

Campaign Overview

Click into a campaign to see its Overview tab. At the top you'll see the Mailed number which includes all requests that have or will likely move to production, total Spend which includes any requests that have or will incur a cost as it moves through the system (i.e. production and/or data appends) and, if you're sharing transactional data with the platform, CPO, ROAS and Revenue for the campaign's set Attribution Window.

Below, you'll see a data graph which is controlled by the adjustable calendar.

On the right hand side you'll see the campaign's status, and the option to Edit or Pause the campaign at the top, followed by the unique campaign_id and a summary of the campaign's settings. All settings can be updated at any point by editing the campaign. The option to archive a campaign will appear once a campaign is paused.

Campaign Active indicates a campaign is available for launch. A campaign will not start mailing unless it is hooked up to a live trigger or specifically launched via One Time Send.


At the bottom of the page is a detailed attribution analysis divided by each creative mailed. If you're sharing transactional data with Poplar and the campaign has been in-home for the 30-90 day attribution window, this section breaks down campaign's success and is especially useful if comparing against a holdout group or A/B testing different creatives.

Visible attribution metrics can be adjusted using the columns filter to the right. Descriptions of each metric appear when hovering your mouse over the information circle.
