Thanks in advance!

Anyone knows Facebook chatbot sending limit?

If a merchant needs to send Facebook messages via mobile numbers (chatbot), what is the rate limit?
This is a link on this topic but it does not talk about the actual limit:
https://developers.facebook.com/docs/messenger-platform/send-api-reference#errors
This is graph api rate limit:
https://developers.facebook.com/docs/graph-api/advanced/rate-limiting
Thanks!
There are two major types of rate limits that can be encountered by your app, application-level rate limiting and page-level rate limiting.
At Application level limit is:
200 calls/person/hour
which will give you error code:4
At Page level limit is:
4800 calls/person/24-hours
which will give you error code:32
Great description Available Here in this reference.
The updated documentation from Facebook clearly lists out 250 calls per second as a safe limit for the Send API.
The Send API does not have a fixed rate limit, but you can safely send 250 requests per second.

Is it possible to retrieve all unanswered email?

My use case is that I sometimes fail to reply to messages say sent to me via sales#example.com. Hence dropping valuable business development!
I need a way to create a filter to show all the messages missing replies.
I can't seem do this from within Gmail's filter dialog. :(
I have a bit of a stare at https://developers.google.com/gmail/api/v1/reference/users/threads/list aka the new Gmail API and I don't see a way of doing this.
Do you have any ideas? Should I be using IMAP?
you stared at the right place. you can use the gmail-api to fetch all threads:
GET https://www.googleapis.com/gmail/v1/users/me/threads?q=to:sales#example.com
then you'll have to fetch each thread:
GET https://www.googleapis.com/gmail/v1/users/me/threads/<thread-id>?fields=messages
now this will get you the list of messages. if the size is 1, then it's unanswered.

Does Facebook have a maximum number of API connections?

If the answer is yes, then what is it?
By maximum number of connectioned allowed per application I mean how many instances of the same api/key can be used to get the friends list at any one time, will Facebook block too many requests?
EDIT I have been looking at http://developers.facebook.com/ but have not been able to find the answer to my question there.
From their Policy
If you exceed, or plan to exceed, any of the following thresholds please contact us as you may be subject to additional terms: (>5M MAU) or (>100M API calls per day) or (>50M impressions per day).
The only information I was able to find is something in a forum.
http://www.quora.com/Whats-the-Facebook-Open-Graph-API-rate-limit
After some testing and discussion with the Facebook platform team,
there is no official limit I'm aware of or can find in the
documentation. However, I've found 600 calls per 600 seconds, per
token & per IP to be about where they stop you. I've also seen some
application based rate limiting but don't have any numbers.
As a general rule, one call per second should not get rate limited. On
the surface this seems very restrictive but remember you can batch
certain calls and use the subscription API to get changes.
You can see how many API requests your users can have a day if you go to your Insights page and click on "Diagnostics". You can also see some other request statistics if you click on "Performance".
