Which one is for you
Pick Hypertide if
- Fits if you already send through Smartlead or Instantly and want inboxes handled
- Works for people who want to pay per inbox with no package
Look elsewhere if
- Not for you if you need campaigns sent, since a separate sequencer does that
- Watch out: the homepage says 2,200+ sends a month per Entra domain, the pricing page says 6,000+
- Tight if you want a small Outlook order, as the smallest is one domain with 25 inboxes
- Skip it if freshness matters: the footer shows 2024
Pick Premium Inboxes if
- Fits if you want 30 or more inboxes set up and handed over
- Works for agencies that already have a sequencer
Look elsewhere if
- Tight if you need fewer than 30 inboxes, because both plans have a 30-inbox minimum
- Skip it if you want a trial, as there is none
- Watch out: domains are not in the price, so you buy them yourself
- Pricey if you want an account manager, a Slack channel or 24-hour monitoring, since all three need the $4.50 tier

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
