Can two Pagerduty services use the same email address? - pagerduty

I am setting up technical services in Pagerduty for a team and want all of them to use the same email integration, specifically, the same email address.
I see that I am allowed to associate the same email address to multiple technical services.
Is this the right thing to do? If not, what are the drawbacks?

A drawback to this is that you'll get an incident for all of those services that share the email. Depending on the size of your setup, this will cause a lot of noise for oncall.
If you want a single email, I'd suggest a global event rule or event orchestration. This products a single routing key and email but still allows you to use rules to route the incoming event to a specific service.

Allow customers to send from their own domain in a SAAS application

I'm currently running a SAAS application and mails are being sent from our application using Mailjet.
Some of the larger customers have been asking to allow the emails to be sent from their domain (e.g. info#largehotel.com) instead of our system (notifications#saasapp.com).
Are there any initial pointers I will need to look at? I'm guessing they will need to add our SPF records to their SPF records too and that they will need add a DKIM key that we generate for them to add to their records too? Then do some validation on them on the DNS level and mark them as validated?
I have some understanding to have customers run their own domain against our SAAS domain but a bit lost on the sending from their email domain requirement.
First, for the record, my SaaS platform does this (vía option 2b). It’s an e-commerce marketplace and I need the receipts to be sent from the email address of the product seller, not from me (the marketplace)
You have two(ish) options
Send email through your client’s mail servers (instead of mailjet)
Verify the client’s domain on your Mailjet (or similar email) service
option 1
With option 1, you’ll need to ask your client’s IT team to setup a username and password for you to access their SMTP server. This is essentially just like them creating an email account for you to use. This may seem like the easiest path available for you, but there are potential pitfalls and disadvantages:
Doing this, you will lose the mail open/click/bounce tracking functionality you get with mailjet; because you’ll be using the company’s SMTP server instead.
If you’re sending out as a fairly common email address (eg info#your-client.com) the client may already have that account active on their mail servers. That would allow them to receive replies into the existing infrastructure but make them wary of the security issues with sharing a password to their mail server with you.
You might find that they don’t even have the ability to give you a username and password. Modern mail services don’t allow for SMTP access (which is what your web app will need); and security conscious companies require 2 factor authentication on mail accounts (which your web app can’t answer)
Option 2
For this, you will need to ask their IT team to configure some DNS records to prove to mailjet, and to the email recipient, that you’re allowed to send on behalf of your client.
You did this for your own domain when you first setup mailjet. See https://app.mailjet.com/support/how-to-add-a-sender-address,96.htm for what this involves, but it’s a case of asking the client to configure a DNS record.
That tells mailjet that you’re allowed to send on behalf of that domain; but you’ll also want the client to adjust their SPF and DKIM records so as the recipient of the emails knows to trust Mailjet’s servers with emails sent from your client’s domain name. Normally, recipients only trust email sent from your client’s mail server (which you have as option 1) and distrust email sent from SAAS providers.
You will (or should) have done this on mailjet for your own domain already as well. https://app.mailjet.com/docs/spf-dkim-guide
So for this, you’ll need your client to setup 3 DNS records.
If you go this way, you could setup a separate Mailjet account which they and you have access to. That way they ca see their dashboard directly and feel a sense of ownership and security around it. But you won’t be able to markup the price of it 😜
Conclusion
How important is the tracking? If you can’t lose that you need to go with option 2.
How technically savvy is the client? Are they going to be able to have those DNS records changed? Are they going to be (rightly) security conscious around giving you an account on their main mail sever.
Option 2 would be my preference. You might need to hold their hand through the DNS setup so get it configured on Mailjet (And ask about SPF in here to make sure you get it right) so you can provide them with clear instructions of the specific 3 DNS records to create/update.
Whatever approach you take make sure you’re talking to the right people at your clients side soon. Their marketing team may be keen to do this with you, but if their IT feels left out of the conversation they will be difficult to get on board when you need them to make the changes. Us IT folk can be grumpy and obstinate 😀
your web app
This is going to need some adjustment. You probably already store your Mailjet credentials in a file or environment variables; these might need to move these to a dB table so you can relate credentials with specific accounts. But we’d need more info on the web app to be able to speak more to that side of the challenge.
option 2b
just as a note instead of a real suggestion. Be aware that some email service provers allow the sending verification part to be done by sending an email to someone on that domain (eg admin#yourclient.com) and then allowing sending vía the API if the recipient clicks on the approve link on that email. But, even with that setup you still need the client to configure SPF and DKIM on their DNS, so the extra one record isn’t a big ask. AWS’s SES allows for this. This works for me; but I have different requirements around deliver ability, and a large number of non-tech users (as opposed to your one or two big clients)
you can ask your client to generate programmatic(app key/password) user for email need to use for example info#largehotel.com and some other info like (host:gmail, protocol: smtp,...) all basic info needed then in your saas retrieve all this info to create object with client info that you stored before to send email for the target (from developer prospective non network engineering )
The SPF is the most important think to do. In most cases you have to be very careful about the IP reputation, but since you are using Mailjet it's up to them to manage this part.
Be attentive to the overall quality of the email, text/image ratio... Also offers a text body version of the content and dont forget the unsubscribe link. Since you already send emails with your service, I guess it's points are already correct.

emailing in microservice architecture

Sorry about my english - if some thing is not clear please ask me in comments - i will clarify this.
I build system in microservice architecture. I have one service with user information, one service for "offers", and one service for "ideas". Services "offers" and "ideas" comunicate (by Restful API) with "User" service on login and other operations. And i wonder - how to deal with emails? Each service have it separate frontend and send emails after some actions (eg. when some third person open link with some offer the user who create this offer will get email, or when some user create idea the manager will get email). Moreover, on each service frontend, manager can create "periodic" mailing with season statistical data or just some other information. Each service email looks differently and have different content.
I have many choices and don't know which will be better. This are some propositions:
Each service has his own separate emailing system and send all kinds
of email (after action, and periodic) independent.
The "user service" have "engine" to send action and periodic emails and other services give the task. Inside task there is link to service who give task and that link will generate email content (for example witch statistical data in periodic email). This solution is complicated...
The "user service" has only engine to periodic emails (tasks have link to generate email body...) but email after actions are send from each microservice indepenndent
Create new microservice only for sending email (periodic and "after action") with proper API. Ofcourse each service like "offers" should send also link (to themself) in mailing task - this link will be call when the periodic email will be send and the response of this link will be generated body of email....
Which one will be better? Or may be there is some better alternative?
Sending emails it's like making request to another service (via SMTP). So, that's a good approach when every service will be able to send emails.
But, of course there's some common logic for sending emails like rendering templates, sending code, configurations and so on. This logic should be shared between services via common code (dll, package and so on).
So, in this way:
Every service doesn't depend on another service when it needs to send an email
Common code for sending email is shared between services
You don't have development, deployment and network overheads in the case of having dedicated email sending serviced
One drawback of this approach is that every service should have the same email configuration (SMTP address, login, password and so on). But if you share configurations between all services it's not a problem.

How to acheive high email deliverability without sharing data with 3rd party ESP?

We are hosting customer data on behalf of companies/clients, and one of our tasks is to send out a very specific transactional email from us (with our email address as sender and reply-to) to clients customers.
We are trying to move away from storing the personal part of a customers data, including his email address. Of course, in order to be able to send out an email to a customer we need to at some point have access to the email address, but in our view it's a step in the right direction to retrieve the email address from the client during a session instead of retreiving it from our own database.
The problem now is that our unwillingness to have email addresses stored anywhere rules out using email service providers like Sendgrid. Instead we need to send out lots of emails through our own server, and this might hurt deliverability. I've been looking for a kind of "self hosted Sendgrid". One who will enable us to send bulks of emails, and one we can tweak to not store the sent emails.
One solution I've found is sendy.co who defines themselves as:
Sendy is a self hosted application that runs on your web server.
This sound promising, but then I read that emails are sent through Amazon's cloud:
Sendy uses multi-threading to send emails via Amazon SES.
I suppose this leads us back where we started, because then Amazon is storing the email addresses.
As I understand, the high deliverability that ESPs achieve is not only caused by state-of-the-art email headers, but also by their servers being recognized by Google/Gmail, Microsoft and other email hosts. So maybe a high deliverability just isn't possible without an ESP. But is there an alternative approach that lets us acheive relativly high deliverability without needing to involve a 3rd party server to do the sending?
The reason that people tend to pay for this service is because it is reasonably difficult/complicated/time consuming. If sending this email is a core part of your business, you'll want to hire a deliverability engineer to handle this. If it's not, I'd start by contacting the various transactional ESPs and see if you can find one that has an enterprise offering they're willing to tailor to this use case.
I think that I'm a little late to this. I hope that you figured out your question by now.
If you haven't then:
One alternative that you can try is to host your own server with an on-premise option. I would check out SocketLabs Hurricane MTA.
SocketLabs is a cloud ESP, like Sendgrid. But they also have a powerful on-premise option.

Server for proxying emails for the purpose of hiding original address

For an application we are building, it is required to give certain registered accounts the ability to send emails to other registered accounts.
As part of the registration, we obviously collect the real email address of every user.
I do not want to expose any of my users' email addresses so I would like to have the ability to proxy them through fake email address that basically forward to the real email address.
For example, if someone want's to email John Doe, they would send an email to abcdefg12345#mysite.com which would then forward the email to john#johndoe.com.
In case its not obvious, the purpose of this is to protect the end user from spam and keeps their real email address private. Since my application acts as the proxy, I could easily block certain email's from going through.
The most famous example of this is Facebook's email proxy for Facebook Apps.
My Question: Are there any patterns, servers, 3rd party services, or libraries that provide such a feature? Does anyone have any suggestions for how this could be built?
I've never seen a service that offers this directly. The hardest part here is the receiving of the emails and wiring things up to your app for the authentication. You could use a service like http://cloudmailin.com in order to receive the email and then forward it on or even use some sort of custom install. Another option would be to create a script that modifies a server such as postfix's configuration.
Finally although I wouldn't recommend it you could try and create your own mail server to do this. I would read up a little more on SMTP/IMAP and see what options you have.
It looks like there is no 3rd party service or tool\library to accomplish this. It is going to be a bigger task than I was hoping for so I will be putting it off until I have the time to implement it.
I think the solution is to use a mail daemon that has an API or at least allows you to manipulate the users\emails\aliases in it such that you can create new mailboxes on demand and set them to forward from someuser#proxy.mysite.com to user#theirdomain.com
I found out that there are services that provide this type of functionality as part of their offerings:
http://mailgun.net/
http://www.sendgrid.com
Both of these services are very cool and offer quite a bit for sending and analyzing emails including the ability to create forwarding\proxy emails.

How are SaaS/Mult-Tenancy apps implementing email notifications (sending and receving)?

Given multi-tenant application, How are vendors implementing email notifications from an email account setup and programming perspective:
Sending emails could come from a generic account: eg notifications#VendorName.com or noreply#VendorName.com, this seems reasonable considering reply addresses and lilnks can be contained within the email contents.
Receiving Emails: How would an application receive email, for instance; to generate support tickets or assign comments in an email to a project/task. I have seen ID's within the subject and some reply to addresses containing the account name eg: notifications#AccountName.VendorName.com
I realise one can programatically connect to a pop3 server and receive emails and look for the IDs with the subject, but is there a way of setting up and receiving email to a single pop3 account from multiple sub-host name email addresses (not sure on terminology there) eg: noreply#AccountName1.VendorName.com or noreply#AccountName2.VendorName.com and check the Account Name from the address? (similar to checking subdomains on a URL)
Any practices, experience, comments or sughestions?
(not sure its relevant, but using C# asp.net-mvc and services etc)
For sending notification emails, we have a notification send to address associated with each account and simply send from our domain to that address. Our from address is monitored and replies end up in the CSR work queue.
For inbound emails, we use FogBugz (from the makers of Stack Overflow) for case tracking. That accepts new cases via email (e.g. cases#mycompany.com). Tickets are auto-created from the email. My only complaint there is that the customer needs to check an obscure link for case updates (no "my cases" web portal, but maybe that will come out in an upcoming version of FogBugz).
We have a custom field in FogBugz to indicate the customer the ticket is from. We could theoretically write a plugin to FogBugz that auto-assigns that using the senders domain, but I guess the CSR's haven't complained loudly enough yet :-)
We (at muHive) are an inbound email/social conversations management product. If you are looking at a handling inbound email or social media conversations from customers, we have an impressive toolset.
For our own outbound needs, the simplest way is to use an Email sending API. Don't bother with SMTP sending by yourself. We use Amazon SES and have also tried Sendgrid which gave us additional benefits like delivery status and email parsing.
There are two ways in which you can handle multiple accounts to a catch all email address. If your target system can differentiate between different customers and assign tasks to the correct representatives based on either the content/sender, ask all your customers to send an email to support#company.com.
As you rightly said, you could also create *accountName_support#company.com* email addresses and use different accounts on whatever CRM/Support solution use to manage these emails.
Another approach is to have your customers send you an email to support#company.com and you use a rule based system (like muHive) to forward these mails to the appropriate account executives based on the customer/account who sent the mail.
