They are related in that all major email service providers (GMail, HotMail, Yahoo!, Comcast, Verizon, etc) scan email '''content''' on the receiving side with some heuristics to determine a 'spam' score in addition to other more 'technical' measures.
==Reputation==Check at https://talosintelligence.com/ == Audience ==
http://emailclientmarketshare.com/ shows that GMail, which only accounted for 4% of market share in early 2013, accounts for 15% at the end of 2015. Know your market. Know the current devices and technologies in use to read email.
== Content and Tools ==
You want to do an email campaign. You need to know what works and what doesn't in email these days. Email is not the web. It's worse.
But even with these great tools, you still need help.

Premailer is written in Ruby, with a lot of help from Nokogiri, Hpricot and the Sinatra framework (goodbye eruby). The [https://github.com/premailer/premailer source is available] on GitHub. As of 2014, there was discussion of making a 2.0 version, but it's 2015 now and there isn't a separate branch, so maybe the "new version" is just being incrementally built into the current.# Putsmail (https://putsmail.com/) is another free option to test your email messages.

This Rackspace article covers the 3 types of DNS records you need to know about for Email delivery: http://www.rackaid.com/blog/email-dns-records/
Aside from domain SPF records, one option you have for sending is '''SMTP relaying''' your mail off to your service provider such as Google Apps. See
* [https://support.google.com/a/answer/2685650 Mail routing and delivery: Guidelines and best practices]* [https://support.google.com/a/answer/176600 Google Apps SMTP settings to send mail from a printer, scanner, or app]* [https://support.google.com/a/answer/2956491 SMTP relay service setting]
for how to configure your Google Apps domain for '''SMTP relaying'''. Note too that you should set the 'Comprehensive mail storage setting' <ref>https://support.google.com/a/answer/3547347</ref> when using systems (like issue trackers) that deliver mail on behalf of users, via the SMTP relay and you wish copies of those messages to be stored in GMail.
If you are going to send larger volumes of email that surpass the limits of your Google Apps account, you will want to use the services of SendGrid, Dyn, MailChimp (Mandrill<ref>They [http://thenextweb.com/dd/2016/02/25/in-hostile-move-mandrill-gives-all-developers-60-days-to-switch-to-paid-mailchimp-service/ cut off their free developer accounts] giving users 60 days to test and implement a new solution or pay for a MailChimp account</ref>) etc. SendGrid actually has a free service tier for < 17,000 messages per month. These services can not only handle the deliverability aspect, but also handle bounces on transactional email messages too.
=== Postmaster ===
Comcast and others have their 'Postmaster' websites with tools and info for help

Unfortunately, your hosting provider may be crippling your email service without even advertising the fact. https://warrenguy.me/blog/ipv6-digital-ocean-crippled
== Email Handling within specific Apps ==
Many apps not only rely on email, but the built-in mail system is often insufficient for real-world needs. So, you must look to extensions, plugins, or otherwise configure the system to talk to an actual SMTP server.
=== MediaWiki ===Usually, people install MediaWiki in internal environments where PHP's internal 'mail()' might actually work. But if you've got something public facing, your you're going to need something beefier. Looking at the [[mw:Manual:Configuration_settings#Email_settings]], you might think you can You should use [[mw:Manual:$wgSMTP]], however you first need to install PEAR Mail for that (unless or, you run bleeding edge 1.27 which nobody does yet), and there are a ton of problems with that <ref>listed at [[mw:Extension:SwiftMailer]]</ref>, so could potentially use one of the [[mediawikiwiki:Category:AlternateUserMailer_extensions|mw:Category:AlternateUserMailer_extensions providers where there is an extension]] like # [[mw:Extension:SwiftMailer]]# [[mw:Extension:Mailgun]]# [[mw:Extension:SendGrid]] (there is no integration for integrates [https://sendgrid.com/docs/Integrate/Open_Source_Apps/index.html SendGrid] but they might sponsor me to write it {{@todo}} Write an extension for MediaWiki that is based on the [[mw:Extension:SwiftMailer|SwiftMailer extension]] and publish to [[mw:Extension:SendGrid]])
The actual implementation is a [https://git.wikimedia.org/blob/mediawiki%2Fextensions%2FMailgun/master/MailgunHooks.php straightforward hook implementation]
=== CiviCRM ===
The documentation for CiviCRM has a fairly comprehensive guide to setting up your email. http://book.civicrm.org/user/current/advanced-configuration/email-system-configuration/, but it can be daunting and complicated even for someone experienced with mail delivery (e.g. [https://wiki.civicrm.org/confluence/display/CRMDOC42/CiviMail+Installation#CiviMailInstallation-SettingUptheReturnChannel Setting up the Return Channel] depends on your choice of provider, and will degrade your spam reputation if not done properly).
