Allegrow vs MailReach (2026): which should you pick?

Pick Allegrow if

• Fits if you send B2B outreach and want catch-all addresses sorted out
• Works for sales teams that want list cleaning and mailbox health in one place

Look elsewhere if

• Pricey if you are one person: Starter is $99 a month for 5,000 contacts
• Pricey if you want native CRM links, as they sit on $1,340 a month billed annually
• Watch out: the trial leaves out integrations, API access and mailbox connection
• Watch out: extra users cost $40 a mailbox or user, and the Starter page gives no billing period

Pick MailReach if

• Fits if you want warm-up and placement tests in one plan
• Works for agencies warming dozens of mailboxes, at $12.80 each from 51 billed yearly

Look elsewhere if

• Not for you if you want to try it before paying, as there's no free plan or trial
• Pricey if your team sends from lots of addresses, as each one needs its own warm-up
• Skip it if you need list cleaning, or DMARC managed rather than checked
• Tight if a campaign is due soon, as MailReach advises 14 days of warm-up first and keeping it running between sends
• Pricey if you pay monthly, at $25 a mailbox against $20 billed yearly

Allegrow

• The free trial excludes integrations, API access and mailbox connection.
• Starter has no native integrations and runs on credits; extra users cost $40 per mailbox or user.
• Unlimited verification and native integrations need Scale Plus Unlimited at $1,340 a month billed annually.
• The Starter price carries no billing period on the page.

MailReach

• No free plan or free trial is listed; the free spam test is a one-off tool, not a plan.
• The vendor advises at least 14 days of warm-up before sending campaigns, and keeping it running between them.
• Each sending address under a domain needs its own warm-up, so costs grow with every mailbox.
