The Best MailPoet Alternative for WordPress Publishers

If you’ve been using MailPoet and hitting friction, you’re not alone. Deliverability issues, server strain, outgrowing a self-contained plugin. A lot of publishers reach the same wall.

Newsletter Glue takes a different approach. Here’s why it works better for most serious publishers.

How MailPoet Works (And Where It Struggles)

MailPoet stores your subscribers in WordPress, manages your lists, and sends email through your server. That last part causes problems at scale.

When your site is sending thousands of emails, it’s competing with itself. Pages slow down, emails queue up, and deliverability suffers because your server’s IP wasn’t built for bulk sending.

Newsletter Glue Does It Differently

Newsletter Glue doesn’t replace your email service provider. It connects to the one you already use.

MailChimp, Kit, ActiveCampaign, Sendy (Amazon SES or SMTP), Brevo, SparkPost, Omeda, BigMailer. Your subscribers stay where they are. Your automations stay where they are. Your deliverability reputation stays intact.

What Newsletter Glue adds is the part ESPs can’t do on their own: turning your WordPress posts directly into newsletters, without leaving the editor. Write your post, style your newsletter, hit publish. Your ESP handles the send.

Why This Works Better for Growing Publishers

Your server stays fast. Sends are offloaded to your ESP’s infrastructure, which was purpose-built for this. Your WordPress site keeps serving readers without the added load.

You keep your deliverability. If you’ve spent years building a clean sending reputation on your ESP, Newsletter Glue works with that, not around it.

Your subscriber data lives in one place. No sync issues, no duplicate lists, no wondering which tool has the real numbers.

Your workflow gets faster. Publishing a newsletter stops meaning a context switch to another tool. Write once, send from the same place.

When MailPoet Makes Sense (And When It Doesn’t)

MailPoet is fine if you’re starting out with a small list and no existing ESP relationship.

Newsletter Glue is worth a look if:

• You already have an ESP and don’t want to migrate subscribers
• Your list is large and server resources matter
• You publish frequently and want a tighter post-to-newsletter workflow
• Deliverability is critical and you want your ESP’s sending infrastructure doing the work
• You run a news site where editorial speed matters

The Bottom Line

MailPoet puts newsletter infrastructure inside WordPress. Newsletter Glue puts your WordPress content inside the newsletter workflow you already have.

For publishers serious about deliverability, performance, and speed, Newsletter Glue is the better fit.
