Software.
I have used both.
I have used a service from
http://www.yunau.com and found it to be cumbersome to use and the costs got out of hand as the mailing list grew past 5000.
They were charging 3 cents per message which is very reasonable for low volumes, but not for high.
I have used a service from
http://www.blacktie-colorado.com/ and found it to very poor. Editing recipients was difficult and it changed my HTML code in the newsletter!
This service is free (included in membership cost) but the homegrown code is poor.
I use a software product called Broadcast from Aestiva (
http://www.aestiva.com ). I use it to send out a monthly newsletter for one of my clients to 15000 recipients.
Broadcast is a server-based, browser-controlled product.
Pricing for Aestiva's Broadcast is:
Bronze Gold Platinum Titanium
2,500 10,000 50,000 Unlimited
$599 $1,499 $2,495 $4,999
I also use a software product called Group Mail from Infacta (
http://www.infacta.com ). Group Mail runs on my Windows PC.
Costs are very reasonable at:
Group Mail Plus, unlimited, $179.95
Group Mail Pro, unlimited, $99.95
Group Mail Free, limited, $0.00
My preference is for software and not a service. Primarily because service costs can explode.
I can't comment on Karen's product's features, but it does seem reasonably priced.
