There's no reason to compare the pay as you go option if you are charging per subscriber and they have an option to pay per subscriber as well. Right on the MailChimp pricing page is a calculator that will tell you straight up it's $75/mo for 10,000 subscribers and unlimited emails. Sure, you are much cheaper but it's not a fair comparison to say you are charging $30 and they are charging $200 when really there's a $75 option that most people would be smart enough to find and take advantage of.
If I have 10,000 subscribers and I send a daily email so 300,000 emails a month do I pay $30 or $59 using OwlSend?
If I send a morning and an evening email (600,000 per month) do I pay $30 or $89 per month?
I'm confused because in your comparison chart you say $30 to send 10,000 emails. Your pricing says $29 / month. Your FAQ talks about "How much does it cost?
Owlsend application charges a flat fee of $29 upto 10,000 subscribers, $49 for upto 50,000 subscribers and $79 for upto 100,000 subscribers. You can send unlimited bulk emails with Owlsend every month. Amazon SES costs $1 per 10,000 emails sent."
So is it $29 + $1 for that first 10000 emails? If not, why are you talking about SES and how much SES costs? SES [costs] should be a non factor and not even mentioned.
EDIT: In the Pricing section it says "Send Unlimited Emails to 10,000 Subscribers" again, am I still paying $1 per 10,000 emails above the $29 / month just to use your interface?
Yes, It is $29 for 10,000 subscribers + $1 per 10,000 email sent via Amazon SES.
Here is a simple calculation. If you send 5 broadcasts to all your audience of 10,000 people.
It would be
$29 + $5 = $34
Here $29 is a recurring cost and $5 is a variable cost depending upon number of emails sent any month. Amazon SES charges $1 per 10,000 emails through them.
