What is email deliverability?

Email deliverability measures the ability to deliver emails to a recipient’s email inbox. Deliverability is also related to inbox placement – whether your email appears in the primary inbox, the promotional tab, or the spam folder. The best email content in the world can’t make up for poor deliverability.

What affects your email deliverability?

Getting an email in an inbox depends on many factors that determine whether an email is delivered, blocked, or even filtered as junk or spam.

Reputation checks

Mailbox providers check sender, IP address, and domain reputation

Email Authentication

Authentication lets ISPs to approve the legitimacy of email sends

Email engagement metrics

The percentage of opens and clicks affect email sender reputation

Email Volume

The volume (like drops or spikes) of email campaigns sent

Bounce rate

Bounces are emails that fail to reach the subscriber

Spam Complaints

How can you improve email deliverability?

ActiveCampaign makes these 6 email deliverability best practices easy, to help improve your email deliverability score.

Practice email list hygiene

List hygiene is critical to maintain a good sender reputation. ActiveCampaign makes list cleanup easy by automatically reviewing and removing inactive addresses so lists are always up-to-date.

Send engaging content

Low open rates signal that contacts aren’t engaged with your emails. ActiveCampaign has pre-built automations and re-engagement campaigns to keep engagement high with consistent, relevant content.

Choose double-opt in

Double opt-in means contacts receive an email to confirm their list subscription. ActiveCampaign makes double opt-in easy so your lists see better engagement metric results, and your sending reputation is strong.

Make it easy to unsubscribe

Unengaged recipients cause email deliverability to drop. ActiveCampaign includes an opt-out link in every email so your entire list is made up of engaged contacts that want your emails — and get them.

Monitor your campaigns

An active and engaged list helps maintain list hygiene. ActiveCampaigns automatically monitors key email metrics like clicks, opens, and bounces to help determine how relevant and engaging your emails are.

Choose a reputable provider

Not all email providers have great deliverability. ActiveCampaign has a best-in-class email sender reputation and works with our customers to keep their email score rate high.

We deliver to the highest standards

We’re confident in our deliverability standards, working as hard as you do to protect your email deliverability, provide the stability you need, and help you stay compliant.

We control our infrastructure, so you stay in control of your email’s impact.

Other solutions may outsource to 3rd party vendors where they have little control or insight into their email reputation. Unreliable deliverability means fewer emails in inboxes, fewer clicks — and fewer sales. Since we own our full delivery stack, that means:

Your emails are trusted.

Your messages appear more trustworthy to mailbox providers (like Google or Microsoft) and ISPs (like Comcast, GMX, or Orange), and less likely to be marked as spam.

Send more emails, faster.

We send hundreds of thousands of messages per minute with complete control over the reliability, scalability, and resiliency of our system.

You save money.

Managing MTAs in-house costs a fraction of a premium third-party vendor — and we pass the savings on to you.

You know email grows your business. Our technology gets it in front of people.
