1
00:00:00,06 --> 00:00:03,02
- [Instructor] So our agent has come a really long way.

2
00:00:03,02 --> 00:00:06,00
We have already added three tools to our agent,

3
00:00:06,00 --> 00:00:06,08
the knowledge tool

4
00:00:06,08 --> 00:00:09,04
to gather information about the exhibition,

5
00:00:09,04 --> 00:00:11,07
the calculator tool to calculate a price

6
00:00:11,07 --> 00:00:13,01
for a given booth type,

7
00:00:13,01 --> 00:00:14,04
and a quote generator tool

8
00:00:14,04 --> 00:00:17,05
to actually create a quote in an HTML file.

9
00:00:17,05 --> 00:00:19,02
The only missing piece now is a connection

10
00:00:19,02 --> 00:00:20,04
to an email account

11
00:00:20,04 --> 00:00:23,07
so the agent can actually also send out an email,

12
00:00:23,07 --> 00:00:27,01
either directly through the client or store it as a draft

13
00:00:27,01 --> 00:00:30,00
or send the client to our internal sales team

14
00:00:30,00 --> 00:00:32,06
so they can actually follow up with that person.

15
00:00:32,06 --> 00:00:34,02
Now, that's what we're gonna do now.

16
00:00:34,02 --> 00:00:35,00
The good news is

17
00:00:35,00 --> 00:00:37,09
we don't have to build this email integration from scratch.

18
00:00:37,09 --> 00:00:39,04
In n8n, there are plenty

19
00:00:39,04 --> 00:00:42,00
of pre-built email connectors available.

20
00:00:42,00 --> 00:00:45,06
If you click Tools, you will see that under Other Tools,

21
00:00:45,06 --> 00:00:47,03
there are lots of different integrations

22
00:00:47,03 --> 00:00:50,00
to different email service providers.

23
00:00:50,00 --> 00:00:52,08
If you want to connect it to a custom email integration,

24
00:00:52,08 --> 00:00:54,09
you can use this Send Email tool,

25
00:00:54,09 --> 00:00:59,00
which sends an email using a simple SMTP protocol.

26
00:00:59,00 --> 00:01:02,05
For our purpose now, we will rely on a pre-built connector

27
00:01:02,05 --> 00:01:04,09
that is using Gmail to send out the email.

28
00:01:04,09 --> 00:01:08,05
So just look for Gmail at this tool,

29
00:01:08,05 --> 00:01:10,08
and now you have the possibility to connect n8n

30
00:01:10,08 --> 00:01:12,06
with your Gmail account.

31
00:01:12,06 --> 00:01:16,01
Just select this dropdown and click Create New Credential.

32
00:01:16,01 --> 00:01:18,06
For demo purposes, I highly recommend setting up

33
00:01:18,06 --> 00:01:20,03
a new email account for this,

34
00:01:20,03 --> 00:01:23,02
just for demonstration and learning purposes.

35
00:01:23,02 --> 00:01:24,04
Once you have done that,

36
00:01:24,04 --> 00:01:27,06
as I did it in my case here, you are connected to Gmail

37
00:01:27,06 --> 00:01:31,07
and you can now automatically define which field should be

38
00:01:31,07 --> 00:01:33,05
filled out by the AI.

39
00:01:33,05 --> 00:01:35,01
We can leave the tool description

40
00:01:35,01 --> 00:01:37,05
to be set automatically as a resource.

41
00:01:37,05 --> 00:01:40,05
We don't select message, but we change it to draft

42
00:01:40,05 --> 00:01:43,06
because we don't want n8n to send out emails right away.

43
00:01:43,06 --> 00:01:46,01
For now, we just wanna see if everything is working.

44
00:01:46,01 --> 00:01:48,03
And also at this point, it's quite a good idea

45
00:01:48,03 --> 00:01:50,03
to have a human at least look over the emails

46
00:01:50,03 --> 00:01:52,06
before they are being sent out to clients.

47
00:01:52,06 --> 00:01:55,06
So as an operation, let's create a draft

48
00:01:55,06 --> 00:01:57,09
and then define the different fields.

49
00:01:57,09 --> 00:01:59,06
For example, the subject line,

50
00:01:59,06 --> 00:02:02,02
we could either have AI generate that automatically,

51
00:02:02,02 --> 00:02:05,05
or we could pre-fill it with a custom line

52
00:02:05,05 --> 00:02:08,03
that is always being used as the subject line,

53
00:02:08,03 --> 00:02:11,06
as for example, "Here is your quote."

54
00:02:11,06 --> 00:02:14,08
This can be useful if you want to have more consistency

55
00:02:14,08 --> 00:02:17,02
on especially things like a subject line.

56
00:02:17,02 --> 00:02:19,09
You could of course, also specify a subject line

57
00:02:19,09 --> 00:02:21,09
in the instructions of the prompt.

58
00:02:21,09 --> 00:02:24,00
This will give you a higher probability

59
00:02:24,00 --> 00:02:26,02
that the agent is actually using a subject line

60
00:02:26,02 --> 00:02:27,07
as you define there.

61
00:02:27,07 --> 00:02:29,01
So for now, I don't really care

62
00:02:29,01 --> 00:02:30,04
about the subject line too much.

63
00:02:30,04 --> 00:02:32,07
So I say that the model should define

64
00:02:32,07 --> 00:02:34,06
this subject line parameter.

65
00:02:34,06 --> 00:02:36,02
Next is the email type.

66
00:02:36,02 --> 00:02:38,04
We can select between text and HTML.

67
00:02:38,04 --> 00:02:40,01
In this case, I'm using HTML,

68
00:02:40,01 --> 00:02:42,09
and I'm also letting the agent define the message for me.

69
00:02:42,09 --> 00:02:45,03
If you check again the system prompt, you will see

70
00:02:45,03 --> 00:02:48,01
that the system prompt contains some light instructions

71
00:02:48,01 --> 00:02:51,03
on how the agent should formulate this email.

72
00:02:51,03 --> 00:02:53,02
Of course, you could add your own templates here,

73
00:02:53,02 --> 00:02:54,02
either in the instructions

74
00:02:54,02 --> 00:02:57,08
or customize this message here according to your needs.

75
00:02:57,08 --> 00:02:59,02
Now, there's one more thing we need to add,

76
00:02:59,02 --> 00:03:01,03
which is the two email address.

77
00:03:01,03 --> 00:03:03,04
So this is the email address that should be used,

78
00:03:03,04 --> 00:03:06,04
and this is also something we want the AI agent to control.

79
00:03:06,04 --> 00:03:09,07
So the AI agent should either add the email address

80
00:03:09,07 --> 00:03:11,07
of the client here or the email address

81
00:03:11,07 --> 00:03:14,01
of our internal sales department if the email should be

82
00:03:14,01 --> 00:03:17,03
forwarded because maybe it's a very high-prospect leader,

83
00:03:17,03 --> 00:03:20,00
they inquired for a really large booth size.

84
00:03:20,00 --> 00:03:21,03
Now, let's close this for now

85
00:03:21,03 --> 00:03:22,06
because this is everything we need

86
00:03:22,06 --> 00:03:24,04
to set up the email integration.

87
00:03:24,04 --> 00:03:25,06
And there you have it.

88
00:03:25,06 --> 00:03:28,08
We have now four tools integrated into our agent.

89
00:03:28,08 --> 00:03:31,05
We have the knowledge tool, the calculator tool,

90
00:03:31,05 --> 00:03:34,00
the quote generator tool, and the Gmail tool.

91
00:03:34,00 --> 00:03:36,04
And one quick heads up, of course, now we need

92
00:03:36,04 --> 00:03:39,03
to at least have the email field defined

93
00:03:39,03 --> 00:03:41,01
before we can actually send out an email

94
00:03:41,01 --> 00:03:43,02
or the agent can use that.

95
00:03:43,02 --> 00:03:45,05
So as I mentioned before, at some point we need

96
00:03:45,05 --> 00:03:48,05
to tell the agent that this is a required field.

97
00:03:48,05 --> 00:03:51,00
I added it here in the quote generator tool

98
00:03:51,00 --> 00:03:53,04
where I added few more information about

99
00:03:53,04 --> 00:03:55,04
what is the required information.

100
00:03:55,04 --> 00:03:58,05
Since we need a quote before we can send out an email

101
00:03:58,05 --> 00:03:59,08
and we now need an email

102
00:03:59,08 --> 00:04:02,08
before we can generate a quote, everything is intact.

103
00:04:02,08 --> 00:04:04,09
Just double-check that whatever you need in order

104
00:04:04,09 --> 00:04:07,03
to call these tools is actually available

105
00:04:07,03 --> 00:04:08,08
and you also let the agent know

106
00:04:08,08 --> 00:04:11,05
that these fields are required at some point,

107
00:04:11,05 --> 00:04:14,05
as I did here, for example, in the quote generator tool.

108
00:04:14,05 --> 00:04:18,00
So let's close this and actually see the agent in action.
