New account fee
To prevent people from abusing the free tier to send spam, we charge a one time $5 fee when you add your first domain. You can try the product prior to paying using our demo subdomain with up to 5 recipients.
The fee acts as a "captcha" and protects our customer's sending reputation from being associated with spam.
Pricing examples
The pricing system runs on credits. You purchase credits in $5 blocks which equates to 50,000 credits - equal to 50,000 emails at the base rate described above ($1 per 10k).
[1] Emails consume more than one credit if certain conditions are met. If they are larger than 200kb they consume two credits. If they are larger than 2mb they consume three credits and an additional credit per every 2mb after.
Examples: If you send a 174kb email it consumes 1 credit. A 215kb email consumes 2 credits. A 1.9mb email consumes 2 credits. A 7.8mb email consumes 5 credits. The average email rarely exceeds 50kb so these costs shouldn't be a concern.
[2] If you enable tracking on emails they consume an additional credit per email.
These little fees can be annoying, but they help save you money. Other mail APIs typically cost 5-10 times as much as our base rate, so they are just building these costs in whether you use the feature or not. With PostAgent you can selectively add tracking only for your marketing emails but not for things like reset password emails. This saves your business money.
All accounts get 10,000 free credits at the start of each month. Free credits do not rollover to the next month.
Notice: 1mb = 1000kb
