Field marketers: radius geotag lists for Marketo, Pardot, Eloqua, HubSpot, and Inflection
Every field event starts with the same question: who in our database is close enough to come? RingFence answers it with a geotag list of every postal code and town in range, in a format your marketing automation platform already accepts.
Field marketing is local by definition
Roadshows, executive dinners, user groups, trade shows, customer appreciation events, and partner days all depend on getting the right people into one room. Distance decides attendance. A database-wide invitation produces unsubscribes and noise, and a hand-built city list misses the suburbs where half your accounts actually sit.
What a field marketer needs is a geotag list: every postal code and town within a realistic travel radius of the venue, in a format the marketing automation platform can filter on. That's exactly what RingFence produces, in seconds, for any venue in the world.
Build the geotag list once
- Search the venue. Enter its postal code or town in RingFence, and a radius in miles or kilometers: 25 miles for a dinner, 75 for a regional roadshow, up to 150 for a flagship event.
- Review the rings. Results come back nearest first, with distances. Trim anything across a bay or a border you don't sell into.
- Copy or export. Copy the postal codes as a list (one per line, or comma-separated), or download CSV or Excel with postal code, town, region, country, and distance for your records.
That list now drives every channel: the invitation audience, paid social and search geo-targeting, sales rep call lists, and post-event follow-up.
Use it in your marketing automation platform
Every major platform can segment contacts on a postal code field. The pattern is the same everywhere: a multi-value postal code filter for dynamic audiences, or a list import for static ones. Menu names vary by version and by how your admin configured fields, so check with your ops team, but these are the usual routes.
Adobe Marketo Engage
In a Smart List, add the Postal Code filter with the is operator and paste RingFence's one-per-line list as the values. Save it as a reusable smart list per event, and reference it from the invitation program. For multi-city roadshows, build one smart list per stop.
Salesforce Marketing Cloud Account Engagement (Pardot)
Build a dynamic list with rules on the prospect Zip field, or, for long lists, segment in Salesforce on the mailing postal code and sync the result. For one-off invitations, a static list built from an import works too.
Oracle Eloqua
In a segment, filter contacts on the Zip or Postal Code field and use a quicklist-style condition to paste the full RingFence list in one step instead of entering values one at a time.
HubSpot
Create an active list (segment) with a contact filter on Postal code and the is equal to any of condition, then paste the RingFence codes. The list stays current as new contacts in those postal codes enter your database.
Inflection
Create an audience segment with a filter on the contact's postal code property, matching any value in the RingFence list. If your Inflection setup reads from your data warehouse, you can also load the RingFence CSV as a table and join on postal code for reusable geo segments.
Three data hygiene traps to avoid
- Leading zeros. US ZIP codes in the Northeast start with 0 (02139 is Cambridge, MA). Excel turns them into 2139. Copy codes straight from RingFence, or import CSVs with the postal code column set to text.
- ZIP+4. If your database stores 02139-4307, an exact match on 02139 misses it. Use a starts with condition, or normalize the field to five digits.
- Country collisions. 02139 is also a postal code in Spain and Poland. Add a country condition to the filter so a Spanish prospect with a matching code doesn't get an invitation to Boston.
Roadshows in every market
A European tour with stops in London, Munich, and Paris is built the same way as a US one: one RingFence search per stop, in kilometers if your team prefers, from a dataset covering postal codes in 120+ countries. Where postal data is thin, RingFence still returns the towns in range, so sales can work the list by name.
Prove the radius worked
After the event, export registrants and attendees with their postal codes and join them to the RingFence CSV, which includes each code's distance from the venue. You'll see how far people actually travelled, which rings converted, and where to set the radius next time. That's the difference between "we invited the region" and a field program with numbers behind it.
Let the AI assistant do it
If your team uses an AI assistant, connect it to RingFence's MCP server. "Build the invite geotag list for the Austin dinner, 40 miles" becomes a tool call that returns the complete postal code list, ready to paste into your platform. Details are on the AI agents page.
Frequently asked questions
Does RingFence work with Marketo, Pardot, Eloqua, HubSpot, and Inflection?
Yes. RingFence produces postal code lists (one per line or comma-separated) and CSV or Excel files with postal code, town, region, country, and distance. Those plug into the postal code filters and list imports that Marketo Engage, Salesforce Marketing Cloud Account Engagement (Pardot), Oracle Eloqua, HubSpot, and Inflection all support. RingFence does not need a native connector to any of them.
How do I target contacts within 50 miles of an event in my marketing automation platform?
Search the event venue's postal code with a 50-mile radius in RingFence, copy the postal code list, and use it as a multi-value filter on the postal code field in your platform's smart list, segment, or dynamic list. Then send the invitation to that audience.
What about contacts whose ZIP code is stored as ZIP+4 or loses its leading zero?
Clean the field first or filter with a starts-with condition. Northeastern US ZIP codes like 02139 often lose their leading zero when a file is opened in Excel, so copy codes directly from RingFence or import CSVs with the postal code column set to text.
Can RingFence build lists for events outside the US?
Yes. RingFence covers postal codes in 120+ countries, including Canada, the UK, and 26 EU member states, and towns in 250 countries and territories, in miles or kilometers.
