Hi Cazoomi team we are a huge user of SyncApps in South America and love the product. http://www.kenaz.com.ar/blog
However, we recently ran into issues after we created a new email campaign in Mailchimp and sent it to a list called Leads which syncs with Salesforce Leads, which has almost 50.000 subscribers. The MailChimp Campaign was successfully synced/created in Salesforce, but it only has 5.000 Leads.
The same MailChimp Email Campaign was also sent to our Contacts list in MailChimp with almost 4.000 subscribers (synced with Salesforce Contacts) in which the Campaign was also successfully created in Salesforce yet has almost all of the subscriber's activity (10 less approx) so perfect.
Do you know why there is such a big difference in the Leads List sync?
We think we have found what the problem is in this sync. From the SyncApps logs we can see that there are 10,000s of campaign recipients emails in MailChimp Leads List which are not lead yet in Salesforce. That is why the synced Campaign Responses number in Salesforce is less than the actual Campaign Members in MailChimp.
*Please note Campaign Responses for an email address that is in MailChimp but not in Salesforce will not be synced.
Additionally the number of synced leads (4) compared to the number of leads in Salesforce (>40K) causes a very inefficient sync.
The following is the best practice in SyncApps and most efficient in the sync process.
1. Sync contacts/leads from Salesforce (all records/most of the records)
2. Send email campaign to all/part of the synced contacts or leads in Step 1
3. Sync Campaign Responses back to the synced contacts or leads
