TL;DR -
Large agencies may want to look elsewhere
Everyone else should seriously consider Tier 3 and above.

I use SendFox (ESP), Convertbox (landing page), and Book Like a Boss ("ThankYou" page)
along with some duct tape - this ad hoc stack has served me well for several years now.
Along the way, I have also invested in Encharge and Zagomail ESPs, but actually used SendFox.

Blastable caught my eye recently (with their bold, Miami Vice/Miami Subs color scheme.)
After watching Dave Swift's Blastable review on YT, I purchased Tier 4 (Tier 3 and above allow
up to 5 "sender profiles," so you could potentially send from up to 5 different domains, if needed.)
While cold emailing is NOT allowed, transactional emails and affiliate marketing / promotion
ARE ALLOWED (contact support for best practices.)

Most ESPs charge by the total number of contacts you have (like Blastable's plans on their website.) However, for AppSumo, the Blastable LTD Tiers are based on monthly sending credits.

For example, if you purchase Tier 1 (20k sends), you can have up to 20k contacts.
If you purchase Tier 3 (100k sends), you can have up to 100k contacts. Send limits reset monthly; contact limit is capped by Tier. Deleting contacts will make room for new ones.
Unsubscribes, do not contacts, and bounces DO NOT count towards your contact limit.

After the AppSumo LTD ends, If you need additional sending credits (i.e. a special sale event),
Blastable has temporary options available. Justin has stated - "you’ll be able to purchase
pay-per-send options to send more emails on a pay-per-use basis. We don’t have pricing
for this yet (though it will be heavily discounted compared to our normal pricing)
as we are in the process of building it out."

The onboarding process couldn't be simpler.
It's important to note, that when you upload your list,
Blastable uses their own internal email verification system,
so there is a some delay during this list import verification process.
They recommend importing 1000 contacts at a time to warm them up to Blastable.
Blastable also has plans to offer email verification embedded within opt-in forms.

Custom fields can be added into a URL (i.e. first name, email, address, etc.)
using the tokens provided or any custom tokens you want to add yourself.
Blastable has an AI feature called "perfect timing" where an email can be
delivered when the subscriber is most likely to open it based on their behavior.
Alternatively, you can also send email to contacts at a certain time in their
time zone across the board (i.e. 8:30 am = 8:30am in THEIR time zone.)
Blastable claims deliverability is "over 99% as far as emails being delivered...
average open rates are between 32-33% across all emails sent on our platform."

"Advanced Segment Creation" is included with Tier 3 and above,
but "Super Customized Segmentation" is planned for Q1 2025.
Yes, there's a 'Powered by Blastable' logo at the bottom of every email,
but soon this will contain your affiliate link (if you join their partner program.)

Several points of concern (that were pointed-out in Dave Swift's Blastable review on YT)
were fixed very quickly (be sure to read comments below the YT video.)
The team at Blastable have been very responsive on AppSumo, YT, and via
their internal support messaging system within my Blastable Dashboard as well.

If you think you have outgrown SendFox, you should seriously consider Blastable.
Would I like the option to remove the logo? Sure, but even SendFox charges you more
(per month, as I recall) if you want less branding, custom HTML, etc.

I give Blastable 5 Tacos because it meets my current needs
and feel that Tiers 3 (and above) offer excellent bang-for-your-buck.
