1 1 00:00:01,100 --> 00:00:02,950 Hi guys, and welcome back. 2 2 00:00:02,950 --> 00:00:04,080 In this video we're quickly going 3 3 00:00:04,080 --> 00:00:07,470 to talk about sending emails. 4 4 00:00:07,470 --> 00:00:08,890 We're going to be using this service 5 5 00:00:08,890 --> 00:00:11,020 called Mailgun to send emails, 6 6 00:00:11,020 --> 00:00:12,440 but there's a lot of them, like 7 7 00:00:12,440 --> 00:00:14,313 SendGrid is another example. 8 8 00:00:15,430 --> 00:00:19,430 These email services have API's, 9 9 00:00:19,430 --> 00:00:22,540 and what that means is you can send them some data 10 10 00:00:22,540 --> 00:00:25,300 in a format that they understand and they expect, 11 11 00:00:25,300 --> 00:00:27,060 and they'll do something for you. 12 12 00:00:27,060 --> 00:00:28,313 That's what an API is. 13 13 00:00:29,250 --> 00:00:31,200 In this case, when you send them the data 14 14 00:00:31,200 --> 00:00:34,212 that they expect, Mailgun will send an email 15 15 00:00:34,212 --> 00:00:36,683 to the email address that you tell them to. 16 16 00:00:38,490 --> 00:00:41,400 If you go to Mailgun.com, here you can see 17 17 00:00:41,400 --> 00:00:44,426 some of the example languages 18 18 00:00:44,426 --> 00:00:47,260 and Python is one of them, which is quite nice 19 19 00:00:47,260 --> 00:00:50,480 because it tells us exactly how to use their service 20 20 00:00:50,480 --> 00:00:51,863 to send an email. 21 21 00:00:53,400 --> 00:00:55,150 Something important to note is that 22 22 00:00:55,150 --> 00:00:58,310 this depends on the Requests library, 23 23 00:00:58,310 --> 00:01:01,838 which is now really the standard way of sending data 24 24 00:01:01,838 --> 00:01:05,640 through the internet to another web service. 25 25 00:01:05,640 --> 00:01:08,888 So, if we instal the Requests module, which we will do, 26 26 00:01:08,888 --> 00:01:12,280 then we can send some data in this format 27 27 00:01:13,560 --> 00:01:15,710 and Mailgun will send an email. 28 28 00:01:15,710 --> 00:01:18,950 And how they send an email, we don't care about 29 29 00:01:18,950 --> 00:01:21,713 because that's what the API is for. 30 30 00:01:22,730 --> 00:01:24,610 So, a couple of things that we need is 31 31 00:01:24,610 --> 00:01:26,800 we need to sign up and we need to get 32 32 00:01:26,800 --> 00:01:29,830 the data that they require. 33 33 00:01:29,830 --> 00:01:34,830 That is a URL, something that we send data to, 34 34 00:01:35,330 --> 00:01:39,000 an API key, that's used to uniquely identify us 35 35 00:01:39,000 --> 00:01:41,408 as the makers of a request. 36 36 00:01:41,408 --> 00:01:44,740 And then who the email is from, 37 37 00:01:44,740 --> 00:01:46,610 who the email is to, 38 38 00:01:46,610 --> 00:01:50,260 a subject for the email, and some text. 39 39 00:01:50,260 --> 00:01:52,950 Optionally, we could also include some HTML 40 40 00:01:52,950 --> 00:01:55,793 in the email, if we want, to make it a little bit nicer. 41 41 00:01:57,250 --> 00:01:59,720 So, if you do go ahead and sign up, 42 42 00:01:59,720 --> 00:02:01,840 that will get you an account 43 43 00:02:01,840 --> 00:02:04,530 and you do have to give them some information 44 44 00:02:04,530 --> 00:02:05,770 but you don't have to give them 45 45 00:02:05,770 --> 00:02:07,810 payment information, if you want. 46 46 00:02:07,810 --> 00:02:10,950 But, if you don't give them a credit card 47 47 00:02:10,950 --> 00:02:12,490 you are restricted to send email 48 48 00:02:12,490 --> 00:02:15,080 to Authorised Recipients only. 49 49 00:02:15,080 --> 00:02:17,170 That means that you have to add your email 50 50 00:02:17,170 --> 00:02:19,400 as an Authorised Recipient, in order to be able 51 51 00:02:19,400 --> 00:02:22,180 to receive emails, otherwise it will fail. 52 52 00:02:22,180 --> 00:02:23,900 If you do give them the credit card, 53 53 00:02:23,900 --> 00:02:25,990 that does not mean they're going to charge you. 54 54 00:02:25,990 --> 00:02:29,110 There is quite a generous limit of free emails 55 55 00:02:29,110 --> 00:02:31,610 that you can send before they start charging you 56 56 00:02:31,610 --> 00:02:33,500 and they are quite nice with the limits 57 57 00:02:33,500 --> 00:02:34,720 and so on, so if you do go over 58 58 00:02:34,720 --> 00:02:36,660 a little bit, it doesn't really matter. 59 59 00:02:36,660 --> 00:02:38,290 The limit, as I said, is quite generous, 60 60 00:02:38,290 --> 00:02:42,850 I have yet to go over the limit myself, so there you go. 61 61 00:02:42,850 --> 00:02:45,700 Just make an account and then we can look 62 62 00:02:45,700 --> 00:02:48,050 at what you'll see once you've made an account. 63 63 00:02:50,420 --> 00:02:51,940 Once you've logged into Mailgun, 64 64 00:02:51,940 --> 00:02:55,070 you'll see something that looks more or less like this. 65 65 00:02:55,070 --> 00:02:57,310 Some things may be slightly different, 66 66 00:02:57,310 --> 00:03:01,670 but one of the things will be the Sandbox Domains. 67 67 00:03:01,670 --> 00:03:04,800 This is what we're gonna use to test our application. 68 68 00:03:04,800 --> 00:03:07,470 So, do click on Authorised Recipients 69 69 00:03:08,470 --> 00:03:10,680 and make sure that your email has been added. 70 70 00:03:10,680 --> 00:03:11,810 You'll have to invite yourself 71 71 00:03:11,810 --> 00:03:13,550 and then click a link on the email. 72 72 00:03:13,550 --> 00:03:16,400 That way you can really make sure that it's working 73 73 00:03:16,400 --> 00:03:18,517 before you decide to go down the 74 74 00:03:18,517 --> 00:03:20,215 "create your own domain" route, 75 75 00:03:20,215 --> 00:03:22,083 which we'll look at later on. 76 76 00:03:23,920 --> 00:03:26,320 If you click on the domain, 77 77 00:03:26,320 --> 00:03:29,070 then you'll see some information. 78 78 00:03:29,070 --> 00:03:31,680 We will need this in order to send email. 79 79 00:03:31,680 --> 00:03:34,530 One of those things is the API key, 80 80 00:03:34,530 --> 00:03:36,800 another one is the URL. 81 81 00:03:36,800 --> 00:03:38,120 So, we'll need both of these 82 82 00:03:38,120 --> 00:03:40,083 in order to be able to send our emails. 83 83 00:03:41,000 --> 00:03:44,550 Notice that there is some sort of email account here, 84 84 00:03:44,550 --> 00:03:47,310 but you don't need this one for anything. 85 85 00:03:47,310 --> 00:03:49,740 So, that's just if you want to log into this account 86 86 00:03:49,740 --> 00:03:52,400 through an email client, which we don't want to do. 87 87 00:03:52,400 --> 00:03:55,523 So, all we need is the API key and the URL. 88 88 00:03:56,880 --> 00:03:58,140 Once you've got those two, and you've 89 89 00:03:58,140 --> 00:04:00,550 added yourself as an Authorised Recipient 90 90 00:04:00,550 --> 00:04:02,290 we're ready to move onto the next video 91 91 00:04:02,290 --> 00:04:03,870 where we're going to start sending email 92 92 00:04:03,870 --> 00:04:05,840 from within our app. 93 93 00:04:05,840 --> 00:04:06,790 I'll see you there.
