One Time Sends
Launch a batched mailing in minutes
Once your campaign has been created, creative files uploaded and a credit card is on file for your account, you can launch your mailing via One Time Send. Before initiating, we recommend downloading and reviewing CSV file formats and guidelines:
Mail File Template - Sheet1.csv
Mail File Template
Click into the campaign, navigate to the One Time Sends tab at the top and click New One Time Send.
If you're interested in receiving a physical sample of your creative before launch, you can do so via the One Time Send option from within your campaign. Select Send Sample, then input the address for delivery:
Depending on mailroom policy, sending to a residential address may be more reliable than sending to an office building.
Once the mailing is done processing, you'll be able to see a preview of the mailer along with a delivery date estimate, and live status updates on where it is in the mail lifecycle from production to delivery from the campaign's History tab.
Uploading a mail file is the ideal choice for launching batched campaigns via One Time Send and are the only other option, aside from trigger setup, for supplying custom merge tag data. Pick Upload Addresses to drag & drop your address file.
You'll be prompted to map your file columns to the required data for mailing, as well as any custom merge tags (if applicable). If any required data columns are missing, you will not be allowed to proceed to the next step. If any of the value in your data column are empty or improperly formatted, you'll see a warning but will be allowed to move forward.
If you've already uploaded your audience file to the Audiences page, you'll see it available for selection if it has finished processing:
Do not select this option if your creative contains custom merge tags. The page Audiences does not store custom merge tag data, so your merge tags will not populate.
Select the Upload Addresses option instead.
Email is the only required column for uploading email data for address enrichment. Including additional info such as name or phone number will not aid in the match process.
Typically, Poplar's address enrichment process sees a 50-70%+ 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. Read More
Lookalike models are special, custom prospecting lists created from traits and/or behaviors identified within your existing customers. These can encompass purchasing behavior, interests, affinities, and additional predictive traits you wouldn’t initially think of.
- Total Records refers to the number of records in your file.
To ensure the highest likelihood of deliverability to we recommend the Strict setting. When mailing to commercial addresses, you may want to try adjusting to Normal or Relaxed depending on the confidence in your data. A CSV record of invalid addresses is available for download, this contains an explanation of the invalid tag if you'd like to review and make adjustments. Read More
Review all details before finalizing. You'll see a preview of the send and the final cost. If you do not have sufficient credit in your account, there will be an attempted charge to the card on file.
We recommend naming your send with a description, this is especially helpful if you plan to mail the same campaign more than once. Instead of creating multiple campaigns from scratch, you can launch multiple One Time Sends under the same campaign and adjust the campaign settings as you go, if necessary.
Once you click Process Mailing, there is a 30 minute grace period to cancel a send. Within this time-frame, head to the One Time Send Overview page to hit Cancel or Send Now. Just as with email, once the send has processed it cannot be reversed.
Once your send has finished processing, head to the History tab to see a record of each individual mailer. Click into one of the items to see a PDF preview with the individual address data and merge tags applied, along with the Request Details and Event Log. The Event Log tracks each mailer as it moves through the mail stream, based on scans updated by the USPS.
A typical mailing transitions through a number of states during its lifecycle. These states indicate where it is in the preparation, production and mailing process. You can see many of these states when viewing a campaign on the web or when querying the API, this value is presented in the
To make it easier to see quick status of a campaign or one time send, we roll up one or more individual mailing states into easy to read groupings.
In some instances a mailing will never receive a USPS scan event and will be remain in the In Production state. Generally this should be under 5% for any given campaign but the piece would be expected to still be delivered in this instance.
