It has been estimated that just under 80% of emails sent by email marketers to people who signed up to your list reach the inbox. This is a pretty staggering number when your recipients have subscribed legitimately. This is because spam filters are becoming increasingly sensitive to make sure that non-legitimate emails do not get delivered. To avoid your email ending up in the spam folder, there are some simple things you can do.

Have a good email list

It is important that you make sure that the people you are emailing want to hear from you. We do not recommend that you buy or rent email lists that you can’t trust the source of, and it’s crucial that your list members have opted in to receiving your correspondence.

The easiest and most common way to do this is to get them to subscribe to a mailing list, either via a website or links on social media. You can assume that, if people visit your site, they are likely to be interested in the information/product you provide. You could add a sign-up box on all of your pages to allow users to join the list.

Ask your recipients to put you on their contact list

It is pretty much guaranteed that emails are delivered to the inbox if your list members have added you to their address book/contact list. In your welcome/first email you could ask them to add you to their contact list. You could also ask them to do this in the body of other emails that you send.

Mind the subject line

It is important to take care with the subject line of your email as it can affect the likelihood of your email avoiding the spam folder.  We have written another short post on how to write a good subject line – the key message is that it should not be too much longer than 35 to 50 characters. The longer the subject line, the more likely it is that the email will go to the spam folder.

Make it easy to unsubscribe

While this might sound counter-intuitive, making the unsubscribe link visible on your emails can actually help overall deliverability to your list. It is preferable that your recipients choose to unsubscribe themselves, rather than marking your email as spam.

Email providers such as Gmail, Hotmail and others keep track of spam complaints and may penalise you, affecting how many of your other emails are delivered. If you make it easy for your list members to unsubscribe, the risk of the email service provider blocking all the emails you send is minimised.

Don’t forget that it is important to understand that there are laws governing the sending of emails to a list – you can read more about email spam and the law in one of our earlier posts.

We have written on this blog before about the importance of email deliverability and what we do to ensure your emails reach their recipients. Spam filters implemented by different email clients (Gmail, Yahoo, Hotmail, etc.) are becoming increasingly sensitive, to make sure that non-legitimate, spam emails aren’t delivered. Ensuring emails are delivered to the inbox is pretty much guaranteed if your list members have 'whitelisted’ you. This means, simply, that you (as the sender) have been added to their list of 'approved’ or 'safe senders’. Different email clients carry out the whitelisting process in different ways and use different terminology. In this short post, we explain how to whitelist email addresses in Gmail.

'Safe sender’

Gmail is pretty efficient at identifying non-important and potentially harmful emails that you probably don’t want to open. However, it isn’t 100% correct all of the time and, to make sure important emails never end up in the Gmail spam folder, you can tell Gmail that emails from a particular sender are safe, allowing those messages to pass through the filter. If important emails keep getting sent to your spam folder in Gmail, you need to add email addresses to the safe senders list to whitelist them.

Set up a filter

In Gmail, it is possible to set up 'filters’ to whitelist a sender (or senders). You can apply a filter to a specific email address, a whole domain, or a mix of both. First of all, click on the gear icon in your inbox and select 'Settings’ from the menu. Then, select the 'Filters and blocked addresses’ tab when viewing the Settings menu. Click the link called 'Create a new filter’ (if you have a lot of filters in place already you’ll see this at the bottom of the list, like in the diagram below). Select 'Never send it to spam’. This will make sure emails that match the filter description will always reach the inbox.

Filtering a specific email address or a whole domain

In the 'From’ field, enter the email address in full that you would like the filter to apply to. If you want to filter a specific email address, write the whole address, like 'johnsmith@emailbusiness.com’. If you want to whitelist all emails from a specific domain, you can just type '@emailbusiness.com’ to put all emails from this domain on the list of safe senders. There are other options but the 'From’ field must be filled out.

Filtering more than one email or domain

You do not need to repeat these steps for multiple emails and/or domains. A handy tip is to put a vertical bar (Shift and then the backslash '\’ key, with a space before and after it) between the separate emails you wish to filter. For example: johnsmith@emailbusiness.com | janesmith@emailbusiness.com | simonsmith@emailbusiness.com.

Alternatively...

You can also filter messages directly from an email as you receive it. So, if you find an important email in your Spam folder, which should have come to the Inbox, you can open it and then apply the filter so it ends up in the right place next time. When you have the email open, click on the vertical dots in the right hand corner and then select 'Filter messages like these’ (see below).

The email address of the sender will then be auto-filled in the next form in the 'From’ field and you can create a filter from there, as before.

Don’t forget

It is worth knowing that when you whitelist an email or domain in Gmail, the filter does not work retrospectively. That is, it does not apply to emails that are already in the Spam/Trash folders.

A daily digest summary is an email containing a compilation of new emails sent by members of a list. This can be a handy function to avoid clogging up members’ inboxes, reducing the number of emails they have to scan each day. To receive an email digest, members will need to opt to receive it. In this short post, we explain how to set up daily digest summaries with Simplelists.

Pros and cons of email digests

Daily digest summaries can be useful for busy lists. Instead of receiving emails when they are posted, Simplelists list members can receive one email every 24 hours. This prevents members becoming inundated with emails when discussions are active and allows them to pick and choose which email discussions are more important for them to read, at a time that suits them.

It can sometimes be tricky to ensure optimum formatting of digest emails, when the original emails are pulled automatically into the digest. The digest needs to be appealing to read and easy to navigate. It can also be a challenge to decide which information should be included in the digest. Too much or too little information may have the same effect as being inundated with individual emails – members may simply delete it.

An easy-to-digest digest

To make sure digests are accessible and appealing to Simplelists list members, most formatting is stripped from the emails, in order to create a clean, easy to follow summary. A link is included for each message, which allows members to reply back to the list. If archives are enabled, links to attachments and the original emails are contained in the digest.

Enabling digest summaries

Enabling daily digest summaries is very easy. Log in and navigate to list members in the left hand menu. In the Address Book, you can see which members receive summaries and which don’t – a cross or a tick will appear next to their name in the ‘Digest format’ column. To enable daily digest summaries for specific members, edit their details by ticking the checkbox next to their name and selecting ‘Edit’. On the Edit Members screen, you can then check the ‘Digest’ box and then ‘Update’ to ensure that they receive it (a green tick should now show next to their name when you return to the Address Book).

When adding members to your list in bulk, you can set all members to receive digest summaries. Click on ‘Add many’ in the Address Book and then add your members’ details. Before clicking ‘Add Addresses’, make sure you have checked the ‘Set added members to receive daily digest email’ box on the left.

You can watch a demo of enabling daily digest summary emails in this short video.

A recent study carried out by ReturnPath estimated that only 79% of emails sent by legitimate email marketers (i.e. emails sent to people who signed up to your list) reach the inbox. Spam filters are becoming more and more sensitive, to ensure that non-legitimate, spam emails don’t get delivered. It is important to follow a simple set of rules to ensure that your list members receive the emails they have signed up for.

Build a good email list

The most important thing you can do to ensure that your emails get delivered to the inbox is to ensure that the people that you are emailing want to hear from you. It is not advised to buy or rent email lists that you can’t trust the source of, and it’s important that your list members have opted-in to receive your list. The most common way to opt-in is to subscribe to a particular mailing list, either via a website or a social media link. If people visit your website (regardless of whether they purchase something), they tend to be interested in the information you are providing. You can include an email sign-up box on all pages, allowing users to join your list. A 'soft opt-in’ is is when a customer has bought something from you and, on this basis, you assume that they might like to receive information about other products/services. They might also have opted in 'softly’ if they have been given the option to refuse to receive communications from you and they chose not to select this option.

Ask your recipients to add you to their contact list

Getting emails delivered to the inbox is pretty much guaranteed if your list members have added you to their address book/contact list. You can ask them to add you to their contacts in the first welcome email that you send them when they sign up to receive your messages. It’s also a good idea to remind them in the body of other emails that you send.

Take care with your subject line

The subject line of your email will also affect the likelihood of your email making it to the inbox.  We have considered how to write a good subject line in a previous post - the key message here is that your subject line should not be significantly longer than 35 to 50 characters because the longer it is, the more likely it is that it will go to the spam folder.

Make it easy for them to unsubscribe

This might sound like a strange one but making the unsubscribe link prominent can actually help overall deliverability to your list. It is much better if your recipients choose to unsubscribe, rather than marking your email as spam. Email service providers such as Gmail, Hotmail and others keep track of spam complaints and may penalise you for it, affecting how many of your other emails get delivered. By making it easy for your list members to unsubscribe, you minimise the risk of the email service provider blocking all the emails you send.

Finally, it is important to understand that there are laws governing the sending of emails to a list - you can read more about email spam and the law in one of our earlier posts.
