Our Customers
Love Us

Interspire has by far the best support for any ESP I’ve used. Their team was amazing and quickly helped resolve any issues I’ve had with the system.

Ryan J.

Resilience Media

“Interspire was recommended to us about 6 months ago, and we are delighted with it. We send about 20,000 emails monthly to our registered users, and it does exactly what we need it to do, with the added benefit that we no longer need to buy email credits. Their customer service has been equally excellent – prompt and helpful – every time we needed help.”

“Our monthly email newsletter is a breeze with the simple-to-use template and contact list creation system. You can use the built-in templates or create your own. Photos are a snap to upload. Anyone can use the simple editor. You can easily segment lists, schedule campaigns. The stats are readily available … opens, clicks, shares, etc.”

Carolyn Worthington

Interspire software makes sending emails easy and straight forward. Setting up Interspire to send an email takes just a few minutes. The price itself is incentive enough and the support staff is prompt and very helpful. I would definitely recommend using Interspire.

Frequently Asked Questions

What do you mean by unlimited contacts, segments, emails, etc.?

Interspire is offered for a one-time purchase; there are no additional charges based on the number of contacts or number of emails you send.

Does Interspire have sending limits per hour or per day?

No, Interspire does not have sending limits, and you can send in excess of 60,000 emails per hour with an optimized set-up. However, your ISP / SMTP provider might have sending limits, and you should also keep in mind the factors that affect email send rates.

How can Interspire help in improving email deliverability?

Deliverability depends on many factors, and Interspire has advanced tools such as our integrated spam-checker and automatic bounce processor to help in that regard. In addition, following email management best practices also improves email deliverability. Please consult our comprehensive guide.

Do you offer multi-lingual support?

Yes, Interspire supports different languages. Language packs are available through third party providers.

Do I have to pay monthly fees?

Interspire is sold as a one-time purchase. After the first year, you can renew the optional support and maintenance period if you want to.

Why is there a maintenance renewal if Interspire is sold as a one-time purchase?

Interspire is sold under a perpetual license: you can use the specific version you have purchased for an indefinite period of time. Regular renewals of maintenance and support are optional but highly recommended as they allow you to continue receiving updates and support after the first year of purchase.

Do you have any money back policy?

Interspire offers a 30-day money back guarantee provided that: 

  • The Interspire team was contacted and allowed to troubleshoot the product installation. 
  • The refund is requested within 30 days of purchase.

I don’t know how to install the software, can you help me?

Of course. With the pro-installation, we will install the Interspire software and other components such as missing PHP modules from the defaults.

What are the requirements to run Interspire on my server?

Interspire runs on a UNIX/Linux with a LAMP/LEMP stack. Please review the detailed requirements here.

Is the source code available?

Yes, the source code is available and can be modified, except for the license verification code.

We are unable to support any modifications made by you or a 3rd-party, and we do not take responsibility regarding the compatibility of the changes made with subsequent Interspire versions.
