Spam management and delivery rates

It’s becoming more common for people to report emails as spam, even if they signed up to a list in the first place. If enough emails are reported as spam, delivery rates can be reduced and in the worst case scenario email addresses can be blacklisted and emails won’t get through at all.

Management of email addresses that have marked an email as spam is critical in keeping delivery rates high and preventing email lists from being blacklisted. You’ll be happy to know that Simplelists fully manages spam reporting for you, ensuring that your emails continue to get through.

What happens when someone hits ‘report spam’?

When a list member marks an email as spam their email provider creates a ‘feedback loop’, which automatically notifies Simplelists. We receive reports from email providers such as Gmail, Yahoo mail, Hotmail and a number of Internet Service Providers.

We use this information to automatically remove the email addresses of people who reported emails as spam from your list(s). This prevents them from receiving further emails from the list and from repeatedly marking emails as spam.

By taking this action Simplelists keeps your ‘marked as spam’ rate low and helps ensure that the delivery rate of your emails is as high as possible. It also helps to keep your list up to date with those people who really want to receive your message.

Emails accidentally marked as spam?

Occasionally people can accidentally mark emails as spam – if this is the case they can always subscribe to your list again in order to receive emails.

Ideally you want accidental marking as spam to be kept to a minimum – here are a few tips on how to achieve this:

Keep your branding consistent. If you have set up a list and people have subscribed to it, try to remove anything that could cause confusion, such as: changing the name of the list; using a different name from your company or organisation name; adding members to a new list with a different name; using an acronym rather than the full company name. Ideally, your branding should be recognisable every time so that your members can look at your email and immediately remember why they subscribed.

Ensure subscribers are clear about what they signed up for in the first place. If they’re not getting what they thought they opted-in to, or there is a long delay between subscribing to the list and receiving the first email, they may have lost interest or even forgotten that they originally subscribed.

For a more in-depth look into using subject lines that will help prevent emails being marked as spam please see this post.

It can be worth noting that marking as spam can be an invaluable source of information about your members’ behaviours and preferences. If a particular list is producing a lot of complaints, it is worth investigating further.

Using a Subdomain for List Emails

We’ve recently produced some videos with instructions on how to use your own domain with your email lists. The main advantage to using your own domain is that you can brand the entire Simplelists system as your own.

You can include your logo, branded landing pages and use your domain as the list email address – you’ll completely replace all the Simplelists branding. This will create a professional image and strengthen your brand.

Domain or Subdomain?

An important point to note when setting things up is that you can only use a domain for email with one host. If you don’t already use your domain for emails then you can go ahead and use it for your Simplelists email without a problem.

However, if you already use your domain for emails with your web host (e.g. for personal or business emails) then you can’t use it for Simplelists at the same time. You could use another domain with Simplelists but this wouldn’t be good for branding – strong branding relies on consistency so using different domains will weaken it.

A good solution in this case is to set up a subdomain with your web host and use that as your Simplelists emails. For example…

Your domain is and you already use it for business emails like,

To brand your Simplelists system and also keep your business emails running set up a subdomain with your web host such as, or You can usually set up several different subdomains with your web host at no extra cost.

Then use the subdomain for your Simplelists emails – remember that you can have as many lists as you like:, and are some examples.

For full instructions on using your own domain with Simplelists see these two short videos.

Simplelists API (beta)

Simplelists is designed to be really easy to use with only very basic computer skills needed to manage your email list – if you can click and type you can use Simplelists! However, there are also a range of technical features which open up a world of options for more advanced users. One of these is an API…

What can you do with the API?

The Simplelists API allows you to automatically synchronise your Simplelists members list with the contact list in another website or system. This opens up many options such as:

  • automatically adding customers who purchase from your online shop to your Simplelists email list
  • integrating website registrations with your Simplelists account so that new registrations are automatically added to your list
  • removing members from your list when the paid membership of a service expires
  • integrating a company database with your Simplelists account so that new employees are added to the email list and employees that leave are automatically removed

In fact, the possibilities are endless!

In simple terms, how does the API work?

Simplelists provides a computer-friendly interface, which allows another website to
make amendments to a Simplelists contact list, without it having to
login using the normal web-interface, which is obviously designed for

CiviCRM Plug In

The easiest way to use an API is with a module that has been created for an application. Due to the popularity of CiviCRM we have created a (beta) plug-in that allows contacts to be synchorised both ways.

Features include:

  • When a contact is created or updated in Simplelists, it is automatically created or updated in CiviCRM too.
  • For multiple lists groups will be created in CiviCRM, reflecting the Simplelists list membership.
  • A number of options to help synchronise the 2 systems.

For more details on the functionality of the plug-in and for installation instructions please see this page.

API Specification

If you’re a programmer or have someone who can program for you, it’s possible to create your own plug-in to interface with your own system. The details that you’ll need to get started can be found on the API Specification page. There is also a complete example of code (PHP) used to for a complete API, including the code to: ‘Authenticate using User Credentials’, ‘Retrieve contacts’, ‘Authenticate using Authorization Code’ and ‘Obtain a new access token’.

Beta Testing

Note that the API is in beta testing at the minute so the protocol may change in the future.


New – Search Archives!

We’ve added a search function to the archives pages – it enables you to find old emails by searching with keywords. Previously you could browse emails by date or by thread – these browsing functions are still available alongside the new search function. Read on to hear about the special features…


Reasons for the improvement:

Simplelists is constantly being updated and improved in order to make things as user-friendly and useful as possible. We don’t just update for the sake of it though; any new additions should improve the service.

We could clearly see the benefits of this feature: busy long-standing lists can have thousands of emails over many years. New members to these lists will be able to access old emails about a specific subject more quickly and easily. Long-term members can also use the feature to revisit emails that they have seen before.

You asked for it! Several customers requested a search feature for archived emails – we listened and put it in place.

Special Features:

A search function isn’t rocket science – simply navigate to the archives page for your list, type your keyword in the search box and hit the button. There are a few special features that might come in handy though:

Wildcard ‘?’: If you type the ? symbol it will be replaced with any single character. This is useful if you’re not sure how to spell a word. For example, you want to search for an old email that was titled ‘Worthington Event’ but you had forgotten if ‘Worthington’ was spelled with an ‘o’ or a ‘u’ you can type ‘W?rthington’ and the results will show emails with both spellings.

Wildcard ‘*’: If you type the * symbol it will be replaced with any number of characters. So, using teh previous example, if you didn’t know how to spell ‘Worthington’ at all you could type ‘W*ton’ results will show all emails that start with a ‘w’ and end with the letters ‘ton’… including ‘Worthington’.

Search by Keywords for Specific Months: You can narrow your search to specific months by browsing to the month of the email that you’re looking for and then searching – only results from that month will be shown.

Enjoy your search!
