DeBounce comes first: for most small senders the first fix is removing addresses that bounce, and its packs start at $15 for 5,000 checks that never expire. Warmup Inbox is second for cold emailers warming new mailboxes, at $15 an inbox a month billed yearly. GlockApps is third for testing placement and reading DMARC reports, free up to 10,000 DMARC messages a month. Warmy narrowly missed: it warms up, checks lists and monitors DMARC on every plan, but starts at $49 a month, rising with volume. ZeroBounce's ONE plan covers all three jobs at $79 a month billed yearly, for one DMARC domain.

   Most small senders cleaning a list 向け

   DeBounce removes addresses that would bounce before you send: upload a file or import a list from Mailchimp, HubSpot, Klaviyo or ActiveCampaign, with duplicates removed free, or check sign-ups as they happen through the API, a JavaScript widget or a WordPress plugin. Credits never expire and come in packs of $15 for 5,000, $25 for 10,000 or $135 for 100,000, after 100 free credits with no card. Know the limits: catch-all checks cost 10 credits an address, monthly list rechecks cost twice the list size in credits, and it does not warm up inboxes, test placement or manage DMARC.

   2位: Warmup Inbox

   Cold emailers warming new inboxes 向け

   Warmup Inbox builds a new mailbox's reputation by trading emails with more than 30,000 real inboxes, which reply to up to 25% of them on Basic, and shows whether warm-up mail lands in spam or a tab. It works with Gmail, Outlook, Microsoft 365 and Zoho Mail. Basic is $15 an inbox a month billed yearly ($19 monthly) for 75 warm-up messages a day, after a 7-day trial with no card. It is second because it serves cold emailers more than every sender: the cost grows with each inbox, language and SendGrid or Amazon SES warm-up need Pro at $49, and it does not clean lists or manage DMARC.

   3位: GlockApps

   無料プラン · $59/月 から

   Senders testing placement and reading DMARC reports 向け

   GlockApps shows where an email lands before it goes out: send it to its seed addresses and it reports inbox, spam or tab at Gmail, Yahoo, Outlook and others, with SpamAssassin scores, authentication checks and 50+ blocklists. Its DMARC Analyzer reads reports for unlimited domains, and the free plan covers 10,000 DMARC messages a month and 2 spam tests, with no card. It is third because it tests and monitors rather than fixes: it does not clean lists or warm up inboxes, extra tests are $16.99 for 3, and Essential is $59 a month billed yearly but $85 monthly.
