MailBluster and Postmark Pricing Calculation Examples
Let’s conduct a thorough analysis of some pricing calculation examples, combining both MailBluster and Postmark pricing. See how much these two will cost you, both separately and all together. Estimate email marketing pricing as closely as possible.
Example 1: MailBluster Starter and Postmark Basic plan
You can test MailBluster with the Starter plan. This pricing plan offers 3,000 emails for free (once in a lifetime). Yes, with a $0 cost, you can send 3K emails to check if MailBluster can be a suitable email marketing platform for you. If you use Postmark SMTP, then you only have to pay the Postmark bill.
Let’s see the total monthly cost of using the MailBluster Starter plan and Postmark Basic pricing plan.
Note: Why with the Postmark Basic plan? For testing purposes, it’s wise to use the least expensive monthly Postmark package.
| MailBluster pricing | Postmark pricing | Total cost (MailBluster + Postmark) |
|---|---|---|
| Starter pricing plan cost: $0 | Basic pricing plan cost: $15 | $0 + $15= $15 |
Note: MailBluster will require no credit card at this stage.
As you can see, using the MailBluster Starter pricing plan and the Postmark Basic pricing plan for a month will cost you only for the Postmark usage, which is $15.
Example 2: MailBluster Pro and Postmark Basic plan
After completing the Starter plan or sending more than 3,000 emails, you must switch to the Pro pricing plan, which is available for a yearly subscription fee of $60 (equivalent to $5 per month).
Let’s start with the second example of the MailBluster and Postmark pricing combo.
Suppose you use the Postmark Basic plan, which is set to send 10,000 emails a month. Therefore, you want to send 10,000 emails monthly using MailBluster Pro. Let’s calculate the cost:
| MailBluster pricing | Postmark pricing | Total cost (MailBluster + Postmark) |
|---|---|---|
| Email sending cost: (10,000/1000) emails x $0.60= $6 | Basic pricing plan cost: $15 x 1 month = $15 | $6 + $15= $21 |
As you can see from the pricing calculation chart, the monthly cost for sending 10,000 emails with MailBluster Pro and the Postmark Basic plan is only $21.
Would you like to know the email marketing cost if you were to follow this approach throughout the year?
In that case, the yearly email sending cost will be:
$21 total monthly email sending cost x 12 months = $252.
Example 3: MailBluster Pro and Postmark Pro
Suppose you use the Postmark Pro plan, which starts at 50K emails a month. You plan to send 30,000 emails for the first six months and 50,000 emails for the last six months of the year. Want to see the cost according to this plan? There you go!
Let’s calculate the cost of sending 30,000 emails for the first 6 months of the year.
| MailBluster pricing | Postmark pricing | Total cost (MailBluster + Postmark) |
|---|---|---|
| Email sending cost: (30,000/1000) emails x $0.60 = $18 | Pro pricing plan cost: $60.50 x 6 months = $363 | $18 + $363= $381 |
Therefore, the total cost of sending 30,000 emails for the first six months is $381.
Now, let’s calculate the total cost of sending 50,000 emails for the last 6 months of the year.
| MailBluster pricing | Postmark pricing | Total cost (MailBluster + Postmark) |
|---|---|---|
| Email sending cost: (50,000/1000) emails x $0.60= $30 | Pro pricing plan cost: $60.50 x 6 months = $363 | $30 + $363= $393 |
Therefore, the total cost of sending 50,000 emails over the last six months is $393.
This way, your total annual email sending cost will be:
$381 (first six months cost) + $393 (last six months cost) = $774 only.
Note: This email sending plan is excellent, especially for small businesses. Wondering why send more emails in the last half of the year? It’s because the latter half of the year is marked by many special events and occasions, such as holidays and New Year’s celebrations. Therefore, it might require you to send more sales email campaigns than in the first half of the year.
Example 4: MailBluster Pro and Postmark Pro for 100k emails
Moving on to the next MailBluster and Postmark pricing combo calculation example.
Suppose you want to send 100K emails in a month using MailBluster Pro and the Postmark Pro plan. Let’s see what it will cost.
| MailBluster pricing | Postmark pricing | Total cost (MailBluster + Postmark) |
|---|---|---|
| Email sending cost: (100,000/1000) emails x $0.60= $60 | Pro pricing plan cost: $60.50 x 1 month = $60.50 Extra 50k emails cost: (50,000/1000) emails x $1.30 = $65 So, total Postmark cost: $60.5 + $65 = $125.5 | $60 + $125.5= $185.50 |
Note: The Postmark Pro plan is already set to 50,000 emails, so for this strategy, you will need to send an additional 50,000 emails. Additional emails in Postmark Pro pricing start at $1.30 per 1,000 emails.
As you can see from the pricing calculation chart, your total cost for sending 100,000 emails with MailBluster Pro and Postmark Pro for a month is $185.50.
If you want to carry on this way for a year, then your annual MailBluster and Postmark combo fee will be:
$185.50 x 12 months = $2226 only.
Example 5: MailBluster and Postmark Platform plan
Now, moving on to the final pricing calculation example, which is perfect for those who plan to use the Postmark Platform plan or want to send 125,000 emails monthly. This pricing combo example is best suited for businesses with a large customer base that want to send bulk emails. Let’s see what it will cost you to use both MailBluster and Postmark.
| MailBluster pricing | Postmark pricing | Total cost (MailBluster + Postmark) |
|---|---|---|
| Email sending cost: (125,000/1000) emails x $0.60 = $75 | Platform pricing plan cost: $138 x 1 month = $138 | $75 + $138= $213 |
Therefore, as you can see, sending 125000 emails with the MailBluster and Postmark Platform plan will cost $213 per month.
And if you want to do this for a year, then your yearly email marketing cost will be:
$213 x 12 month = $2556 only.
