Is there a difference between a filter that has an (L) appended to it? If so, what does is signify and how do I know if I should/shouldn't use it? My Salesforce admin said there isn't a syntax for it in our instance.
The "(L)" signifies that it is mapped only to the Lead object in SFDC. If you go to Admin > Field Management and then search for "Email Invalid", you'll see two of them in the list - "Email Invalid" and "Email Invalid (L)". "Email Invalid" will likely be mapped to the SFDC Contact object while the "Email Invalid (L)" will be mapped to the SFDC Lead Object.
You can have them merged together so that "Email Invalid" works for leads and contacts, but you'll need to first remove any references to "Email Invalid (L)" anywhere in your Marketing Activities or Design Studio, and then contact support to have them be merged together.
I would also work with your SFDC admin to ensure that "Email Invalid" maps from the Lead Object to the Contact Object at the time of lead conversion.
Super helpful, @Andy. And thank you for such a quick response.
All my best,
Could you please mark my reply as Correct so that we can mark this question as answered?
In addition, please note that Marketo will only append (L), (C) and (A) when multiple fields have the same label. So when you have a (L) field, it usually means that there is another fields with the same label that was created.
