Getting Started

Build Your First Campaign
A guide through campaign settings, capabilities, and how to set up in minutes.
How Poplar Works
Whether you’re a marketing manager, CRM specialist, or agency onboarding client accounts, the Poplar platform provides an easy and seamless way to introduce Direct Mail into your marketing stack.
One Time Sends vs. Triggered Campaigns
A One Time Send or batched mailing is launched to a single static audience list; great for sales events, product launches, seasonal promos, or prospecting lists. Simply upload a CSV of recipients to your Audiences, create a campaign and upload creative, then head to the One Time Sends tab of your campaign to select your audience to launch in minutes.
Triggered sends are programmatic - launched automatically when customers take specific actions in your CRM or ESP (just like an email trigger). Common examples:
Abandoned cart reminders
Post-purchase thank-yous
Win-back or re-engagement campaigns
Integrate Poplar with your CRM/ESP to start sending automatically. All flows and dynamic segmentation is managed outside of Poplar, from within your CRM or ESP.
In-home Timeline
A campaign can be created, and creative artwork uploaded in under 5 minutes. To then launch, you want to either initiate a One Time Send (also takes a matter of minutes) or set your triggered integration live. Once launched, your mailers will move from processing to production before being handed off to USPS for shipping. Poplar offers two shipping speeds: First Class and Standard.

Poplar is optimized for speed, so mailers are sent to production almost immediately and begin printing within 24 hours. From your campaign's History section, you can click into individual mailers and scroll down to the Event Log to see a live timeline of the production and mailing process.
We receive our mailing status scan data directly from USPS. It is important to note that because of the nature of USPS data collection and tracking, a small percentage of mailers may not receive Delivery scans - this is normal and we still assume successful delivery. For additional info or questions, please reach out to [email protected].
Attribution & Reporting
Poplar uses last-touch order matching to calculate attribution. When you share transactional data with the platform (via Shopify, Orders API, or CSV upload), Poplar matches mail recipients to resulting orders so you can measure campaign impact and ROI.
For incremental metrics, make sure you always set a Holdout percentage when creating your campaign.
Poplar does not track promo code redemptions or QR code scans, we consider order matching to paint a more accurate picture of campaign success. Most code redemptions and QR code scans can be tracked using the platform that generated them.
Account & Team Management
When creating your Organization, you'll be lead through a number of steps prompting you to enter info such as address and phone number, team member invites, payment plan selection, and more. Once you've completed onboarding, you can later access all of these settings by clicking your account icon in the bottom left:

Multiple organizations can be created and navigated between via Switch Organization - our agency clients will find this particularly useful.
Data Privacy Compliance
Poplar has built in features to make data privacy compliance easy for our clients. Poplar is set up to process both right to delete and right to access request types. This is separate from an opt out which is handled more as a default audience.
Data Subject Request API
We have 2 endpoints, an opt-out/do not mail endpoint that will add submissions directly to a global opt out list for your account as well as a data subject request (DSR) endpoint that can process the right to delete and right to access requests programmatically. View API Documentation
In Platform CSV Upload
You can upload a CSV of deletion or access requests as well as review historical requests directly from the UI: https://app.heypoplar.com/account/data_subject_requests
Formatting the CSV should be a single type of request per submission and use the standard audience fields. I.e. email, address_1, address_2, city, state, postal_code.
Share Local Media & Poplar Joint Clients
If you work across SLM, Poplar opt outs will apply to all of your client data across our business lines.
Additional Notes:
Data deletions submitted should generally occur within 24 hours.
Please submit all types of PII that you have when submitting opt outs or running a data deletion we do not have any type of global user profiles so if you submit an email it will only run a deletion on any records containing that email (we don’t automatically associate an email with addresses on an order for example)
Data deletions and opt outs only apply to an individual client's data, if you found this article as a consumer wishing to opt out of mailings please contact the Brand directly via their website. To opt out of Share Local Media Shared Envelopes you can go to https://opt-out.sharelocalmedia.com/
