Newsletter - Speed Control
This WordPress plugin gives you control over how quickly your newsletters are sent. You set a sending rate that suits your server, so large mailings go out at a steady pace instead of hitting your hosting all at once. It works for small blogs and for sites with big subscriber lists.

What it does
Sending a newsletter to a long list can put a heavy load on a web server. When too many emails leave at once, the server can slow down or sends can fail, and a sudden burst of mail is more likely to be flagged as spam. Newsletter - Speed Control addresses this by letting you decide the pace of delivery, so your messages go out in a controlled stream that your server can keep up with.
You configure the speed settings from a simple interface and can watch sending progress as it happens. If you prefer not to pick a fixed rate, an optional automatic throttling mode adjusts speed based on how the server responds. Sending logs give you delivery reports to review after each campaign. The plugin is built to work alongside popular WordPress newsletter tools and to keep its own impact on site performance low.
Best for
- Bloggers sending regular newsletters from shared hosting
- Sites with large and growing subscriber lists
- Agencies managing email sending for client WordPress sites

Questions about Newsletter - Speed Control
Why would I need to slow down my newsletter sending?
Sending a full list at once can overload your server and cause slowdowns or failed sends. A sudden burst of mail is also more likely to be flagged as spam. Setting a controlled sending rate keeps delivery steady and within what your hosting can handle.
Do I have to figure out the right speed myself?
You can set a fixed rate if you know what your server handles well. There is also an optional automatic throttling mode that adjusts sending speed based on the server's response, which is useful if you are unsure what rate to choose.
Can I see how a send went after it finishes?
Yes. The plugin keeps detailed sending logs with delivery reports, so you can review how a campaign performed. You can also monitor sending progress while a newsletter is going out.
Will it work with the newsletter tool I already use?
It is designed to work with popular WordPress newsletter plugins, adding control over sending speed to your existing setup. It is also built to stay lightweight so it has minimal impact on your site's performance.
