Looking for the Cheapest LTD?
Mailivery Standard @ $47
Note: It is not mapped to any monthly plans.
You will get updates to the current features that you already have. But you might not get NEW features that the team releases.
(This is what I’ve heard from the co-founders. The plan is custom made to keep the offer affordable — for buyers who don’t need advanced email warmup features)
Next Cheapest LTD?
Mailivery Sophisticated @ $79
(You can find the toggle at the pricing page)
Mapped to the Outreach Pro monthly.
Mailivery Standard vs. Mailivery Sophisticated

What you get from the Sophisticated plan:
👉 For “mimicing natural behavior”, you get advanced behaviors like “random ramp ups”, “custom reply rates”, & more.
👉 For “AI emails”, you get GPT 2 & GPT 3 generated content.
👉 For “Advanced settings”, you get “weekend sending, time zones, & future advanced settings”
👉 Get SPF, DKIM, Blacklist checker
👉 Get future updates of “Outreach Pros” monthly.
Just Want Email Warm Up?
Mailivery Standard
I’ve heard that the team will add cold outreach in the future when the warm-up is mature.
Since the standard plan is not mapped to any monthly plans, you may not get it (other exciting features).
To be safe, just assume you’ll get what you have now and all future updates (not features).
Want Cutting-edge Email Warm Up?
Mailivery Sophisticated
They’re obsessed in making the email warm up as human-like as possible.
Unique features:
-
- GPT-2/3 emails
- Weekdays sending
- Send @ right timezone
- Set reply rate (e.g. 20%)
- Random ramp-up
IMO, an overkill at this moment. I don’t think the spam filters care that much. I’m using normal warm-up and my emails are delivering fine.
But I only send like 100 a day :p
I guess if you’re looking for a SaaS that is always innovating to make email warm-up as natural as possible, Mailivery Sophisticated is suitable for you.
Looking for an All-in-One B2B Tool?
✔️ Find leads? Checked
✔️ Verify?
✔️ Warm up?
✔️ Outreach?
✔️ Personalized landing page?
✔️ Chrome extension to follow up?
✔️ Automatically close your sale? (just kidding, you need to do that yourself!)
In short,
Sales.rocks plan to be your one-stop shop when it comes to B2B lead gen. And they’ve achieved that.
As they focus on many aspects at once, they may fall short in some areas. That’s only normal.
That said, all the features are good for you to use & get appointments now (no excuse!).
They also have a huge team that can push updates in multiple areas at once.
Looking to Find and Verify Leads?
Sales.rocks
Database of 115+ million companies. 200+ million personal contacts. 213 countries.
And they keep growing it.
Tools like these are expensive as they have to constantly scrap & update the data.
Looking for Best Value?
Sales.rocks
They do more than warm up. From lead gen to outreach.
Monthly price starts at $233, but you pay $90 one-time for 5 email accounts.
$18 per email accounts is also the cheapest among all.
Looking to Warm Up Your Team?
Sales.rocks
The offer seems to be designed for teams in mind.
1 code gives you 5 email accounts to warm up. & more if you stack.
Looking for Personalized Outreach?
Sales.rocks
Personalized text. Personalized images, & dynamic landing pages at the roadmap. (Can we have personalized videos too?)
Have integrations with Hyperise & Nexweave for personalized images.
Looking to Warm Up and Outreach?
Mailivery focuses on cutting-edge email warm up.
Sales.rocks wants to be the most comprehensive.
There’s must be a tool that is in the middle, right?
Outreach Bin!
They focus on solving the most important aspect of the sales cycle — Outreach!!
✔️ Send unlimited emails.
✔️ Have unlimited team members.
✔️ Drip campaigns.
✔️ Email warmup.
✔️ With a clean UX & crucial features that work, I’ve learned that users have already sent over 3 million emails using the platform.
Very Impressive.
In short,
Outreach Bin helps you to warm up your email accounts & send automated cold emails.
They might lack some bells & whistles (like website personalization), but it gets the job done and will continue to push in this area.
The user interface is super clean and easy to understand. Log in, get down to work, and book some appointments!
They do not have LTD, sadly. But currently have a 75% OFF permanent pricing for anyone who reads the note. So $39 becomes $9.5.
Looking for the best UI/UX?
Outreach Bin
Easy to use. not confusing. Straightforward.
