Frequently Asked Questions (FAQ)
Do you sync every email, or only campaign emails?
We sync every email that comes through your connected accounts. That’s why it’s called the master inbox. You can choose to only sync campaign emails, but we recommend treating it like an email client and syncing everything.
Do you categorize "out of office" or "automated emails?"
Yep. We take care of these for you, and tag them. You can choose to include them in your reply stats if you'd like. You can also filter them out and push them into followup campaign sequences too.
Can I attach custom tags to leads within the master inbox?
Yep. We auto attach some default tags for you like the lead's email service provider (ESP), but you're welcome to add and assign any custom tags you'd like.
How long does it take for emails to arrive in the master inbox?
Because you're running on dedicated infrastructure, email syncing is near real-time. In some cases, if you have email accounts connected to multiple places (eg other tools), it can take a little longer.
Can I send attachments like PDFs or images in my email responses?
Yes you can.
Can I build my own master inbox UI on top of your APIs?
Yes you can. You can find our full API reference here . Look under the "Replies" resource.
