Email marketing deliverability <\/a> defines what percentage of emails reaches the recipient’s inbox. <\/p>\n\n

In the end, the success of a campaign depends on this: <\/strong> the ability of your email marketing service to get the messages to their destination.<\/p>\n\n

Therefore, choosing a service with high deliverability is essential to optimize communication with your subscribers.<\/p>\n\n

In this article, we will explore the key factors to ensure a high delivery rate in your campaigns<\/strong>. <\/p>\n\n\n\n

Importance of deliverability in email marketing<\/h2>\n\n

Deliverability is vital because it indicates if the emails effectively reach your subscribers. <\/strong> <\/p>\n\n

High deliverability equals a more effective email campaign.<\/strong><\/p>\n\n

In contrast, if deliverability is low, a good portion of your list will not even see your content.<\/p>\n\n

Consequently, deliverability directly impacts the return on investment (ROI<\/a>) of your campaigns. Sending emails with a bad reputation generates distrust and diminishing results. <\/p>\n\n

Therefore, it is not enough to create valuable content; <\/strong> it is key to choose a provider that takes care of the sending process. <\/p>\n\n

A reliable service also simplifies list management and makes it easier to comply with anti-spam rules.<\/p>\n\n

In the end, without deliverability, there is no effective campaign. <\/strong><\/p>\n\n

Sending emails without worrying about reputation may seem easier, but in the long run, it costs dearly in lost opportunities. <\/p>\n\n

Deliverability is quantified as a percentage. <\/p>\n\n

For example, sending 10,000 emails with only 85% delivery implies losing 1,500 contacts in each campaign. <\/p>\n\n

This margin impacts your reach and reduces business opportunities. <\/strong><\/p>\n\n

Hence the importance of improving those numbers.<\/p>\n\n

Finally, the choice of a robust platform directly influences the quality of the campaigns. <\/p>\n\n

A reliable provider applies best practices and stays updated with the rules of email clients. <\/p>\n\n

This way, your messages avoid the spam folder and remain visible. <\/p>\n\n

On the contrary, an inadequate service can reduce your results, no matter how good your offer is. <\/strong><\/p>\n\n

\"Key<\/figure>\n\n

Key factors for high deliverability<\/h2>\n\n

To choose an email marketing service that favors good deliverability, consider these factors:<\/p>\n\n

\u00b7 Sender reputation: <\/h3>\n\n

This depends directly on you.<\/p>\n\n

The domain and email address used must be reliable. <\/p>\n\n

A sender with a good history and authentication (SPF, DKIM, DMARC) improves delivery. <\/p>\n\n

Conversely, new domains or those without configuration can reduce the delivery rate.<\/strong><\/p>\n\n

\u00b7 Quality of the contact list: <\/h3>\n\n

It is fundamental to use clean and opt-in lists. <\/p>\n\n

By sending only to confirmed and active subscribers, you avoid spam traps <\/a> and high bounce rates<\/strong>. <\/p>\n\n

A clean list increases the trust of email providers (destination servers for your emails).<\/strong><\/p>\n\n

\u00b7 Good subscription practices: <\/h3>\n\n

Don’t buy email lists or send unsolicited messages. <\/p>\n\n

Always use double confirmation systems (double opt-in) to ensure your list is composed of genuine contacts. <\/p>\n\n

These practices protect the sender’s reputation and improve deliverability.<\/p>\n\n

\u00b7 Relevant content and clean structure: <\/h3>\n\n

Providers analyze the content of the emails. <\/p>\n\n

Avoid using words that could be considered spam and use simple, easy-to-understand wording.<\/p>\n\n

Likewise, separating the text into brief paragraphs with useful links improves readability.<\/p>\n\n

\u00b7 Consistent sending limit: <\/h3>\n\n

Maintaining a regular sending rhythm improves your reputation. <\/p>\n\n

Sudden spikes can alert anti-spam filters. <\/strong><\/p>\n\n

If you have never done mass mailings before, it is better to start slowly.<\/p>\n\n

\u00b7 User interaction: <\/h3>\n\n

Clicks and opens are signs that your emails are wanted. <\/strong><\/p>\n\n

A good provider allows you to segment lists and personalize messages, encouraging a better response from readers. <\/p>\n\n

Below you can see a simple example of segmentation with Mailrelay:<\/strong><\/p>\n\n

\"\"<\/figure>\n\n

Of course, there are many more options available.<\/p>\n\n

Remember, the more interaction you get, the more ISPs will trust you.<\/p>\n\n

\u00b7 Support and analysis: <\/h3>\n\n

It is useful to have bounce alerts and analysis tools. <\/p>\n\n

Choose a service that alerts about sending errors (bounces, non-existent emails, complaints, etc.) to correct problems instantly. <\/p>\n\n

Active analysis helps prevent penalties for dirty lists or accumulated complaints.<\/p>\n\n

These factors combine to define a service’s deliverability rate. <\/p>\n\n

Make sure the chosen platform addresses every point: authentication, sending quality, and campaign adaptability.<\/p>\n\n

\"What<\/figure>\n\n

What to look for in an email marketing service with high deliverability?<\/h2>\n\n

When selecting the best tool, keep the following in mind:<\/p>\n\n

\u00b7 Robust infrastructure: <\/h3>\n\n

Choose providers with dedicated servers or shared IPs with a good reputation, as is the case with Mailrelay. <\/p>\n\n

A solid infrastructure ensures that your campaigns don’t get stuck or collapse with high traffic. <\/p>\n\n

Robust infrastructure includes redundant servers in various regions, so that in case of a failure, another server replaces it without interruptions. <\/p>\n\n

Likewise, providers with load balancing distribute the emails sent to avoid saturation.<\/p>\n\n

\u00b7 Integrated automation tools: <\/h3>\n\n

Make sure it includes features like welcome sequences, drip emails, and A\/B tests. <\/p>\n\n

These options not only optimize your campaigns but also maintain the audience’s interest. <\/strong> <\/p>\n\n

Mailrelay offers automated email series and A\/B tests in all its plans.<\/p>\n\n

\u00b7 Personalization and segmentation: <\/h3>\n\n

The more relevant your message is to the recipient, the better. <\/p>\n\n

Look for a system that, like Mailrelay, allows you to segment the list with custom fields and create dynamic content. <\/p>\n\n

Personalization increases opens, which reinforces deliverability.<\/p>\n\n

\u00b7 Real-time reports: <\/h3>\n\n

It’s key to constantly measure your email delivery performance. <\/p>\n\n

The best service shows real-time analysis, such as click maps or heat maps. <\/p>\n\n

This way you can adjust your campaigns on the fly and improve ROI. <\/p>\n\n

Not all providers offer this level of support for all users.<\/p>\n\n

\u00b7 Friendly interface and editing with AI: <\/h3>\n\n

Ease of use is crucial. Mailrelay offers an intuitive dashboard and a newsletter editor enhanced with artificial intelligence to write content. <\/p>\n\n

With an easy-to-use tool, you waste less time and avoid errors that could affect delivery.<\/p>\n\n

\u00b7 Flexible integrations: <\/h3>\n\n

Check if the service connects with your current applications. <\/p>\n\n

For example, Mailrelay facilitates the import of large subscriber lists and synchronizes contacts automatically through platforms like Make.com <\/a> or Bitapps.pro<\/a>.<\/p>\n\n
