How do I maximize my E-mail Deliverability Rate?
How do I maximize my E-mail Deliverability Rate?
Updated over a month ago

Are you send your e-mail blast, you realize that many of the e-mails ended up 'Bounced', 'Rejected', or 'Undelivered'.

How did this happen and how can it be prevented?

1) Why is my e-mail's status listed as 'Rejected' in my 'Donor Management' system?

Here are some of the most common reasons e-mails in your 'Donor Management' system can have a status of 'Rejected':

  • your IP address has been "denied" by the recipient (or their e-mail client)

  • the content of your e-mail contains elements the recipient's e-mail provider has flagged as "Junk" or "Spam"

  • there was a technical issue that occurred between the two servers (yours and the recipient's) at the time you attempted to send the e-mail

2) What is a “deliverability rate”?

A “deliverability rate” is the rate at which a particular e-mail was successfully delivered to your contacts without any obstacles, such as getting caught in a "Junk" or "Spam" folder. They are measured in percentages – for example, an e-mail with a deliverability rate of 45% means that 45% of the intended recipients received it with no issue.

3) What is an “open rate”?

An “open rate” is the rate at which e-mails are opened by recipients, instead of being left unread or deleted. A “click-to-open" rate (the “clicked” metric in your 'Email Blasts') is the rate at which individuals who opened that email clicked on the links within – like a link to your donation page, or your nonprofit’s social media accounts.

4) What is considered a “good” deliverability rate or a “good” open rate?

It can be difficult to determine a “good” deliverability rate in the nonprofit sector since several factors can impact how successful an e-mail’s deliverability is. A "good" deliverability rate can depend on how large the e-mail’s audience is, how large the e-mail was, and several other aspects that are difficult to compare across the entire nonprofit sector.

However, nonprofit organizations have one of the highest industry averages for their e-mail open rates, with 20-25% of nonprofit e-mail communications being opened by their recipients. The click-to-open rate for nonprofits can also vary, depending on what kind of link is included in the message. Only about 1% of e-mail recipients click on links within a nonprofit’s e-mail blast – but, nearly 5% of e-mail recipients click links that allow them to share the message or post directly to social media.

5) What causes an e-mail’s deliverability rate to decrease?

Many things can negatively impact an e-mail’s deliverability rate. Here are some of the most common:

  • generic “from” e-mail addresses, such as noreply@yourorganization.com, or development@yourorganization.net

  • using “shortened” URLs for links or buttons within the message

  • e-mail subject lines in all capital letters

  • e-mail subject lines that include special characters or excessive punctuation

  • sending communication infrequently or inconsistently

  • sending an e-mail to a large audience (e.g. 10,000 contacts)

  • sending too many similar e-mails to the same audience within a short amount of time

  • including large attachments, images, or videos

  • inconsistent formatting (such as using multiple colors and fonts)

  • spelling errors

6) How can you improve an email’s deliverability rate?

There are several ways to help increase the chances your e-mail hits more of your contacts’ inboxes:

  • remove any e-mail addresses that previously have unsubscribed or bounced from your mailing lists

  • update your 'Email Blast Senders' in 'Donor Management' (Not sure how? Learn more here.)

  • use the full link (including the https://) when including a hyperlink, image, or button within the body of the e-mail

  • use short, catchy, personalized subject lines that avoid excessive punctuation, special characters, or all capital letters

  • personalize the e-mail by using merge fields to pull in a donor’s name

  • be consistent with your font colors and sizes throughout the message

  • use spell-check

  • send consistent communications to your audience (weekly, monthly, etc.)

  • use filtering and segmenting to share the e-mail with multiple targeted audiences (Want to learn more about filtering and segmenting to send more effective e-mails? Click here.)

  • minimize the size and number of images and attachments included in the e-mail

  • avoid the use of that may trigger e-mail clients to assume the message is not legitimate (Examples: “free gift”, “giveaway”, “miracle”, “promise”, “act now”, “take action”, “dear friend”, etc.)
