Which one is for you
Pick BuzzStream if
- Fits if you pitch journalists or bloggers and need every past conversation kept on file
- Works for teams sharing prospect lists who must not pitch the same contact twice
Look elsewhere if
- Tight if you send pitches in bulk, as Starter has no bulk sends, automated follow-ups or reports
- Pricey if you need the API, which is only on Professional at $424 a month and Custom
- Watch out: contacts count against your limit until deleted, and archiving a project frees none
- Not for you if you want a trial without payment details, as the first charge comes on day 15
- Pricey if you want AI-built media lists, as ListIQ is a separate subscription from $24 a month
Pick ColdSEO if
- Fits if you do your own link outreach on a small budget
- Works for judging a campaign by the links it produced
Look elsewhere if
- Tight if you're staying free: 100 sends, 50 prospect credits and 25 AI first lines a month, from 1 inbox and 1 campaign
- Not for you if you want a trial of a paid plan: billing starts on day one, with a refund only if you downgrade within 14 days
- Pricey if you need more than one seat, the API or white-label exports, which come only with Agency at $159 a month
- Watch out: monthly credits don't roll over, and top-up packs cost extra, such as $15 for 500 prospect credits
- Skip it if you don't have mailboxes of your own to send from
How we grade them
| 2.2GPABuzzStreamFair | 2.0GPAColdSEOFair | |
|---|---|---|
| Value for money | CStarter is $49 a month for 1 user and 500 contacts, right in the middle of what this category charges. Bulk sending and automated follow-ups need Growth at $174 a month for 3 users, and the API needs Professional at $424. | CPro is $63 a month billed annually ($79 monthly) for 5,000 sends, 5 inboxes and 2,000 prospect credits, inside this category's usual range. Running short means one-time packs, such as $10 for 1,000 sends. |
| Free plan and trial | DNo free plan. The 14-day trial takes its first charge on day 15 unless you cancel, so it starts with your payment details. | CFree for good with no card, but 100 sends, 50 prospect credits and 25 AI first lines a month from 1 inbox is a taste you'll use up fast. Paid plans have no trial, just a full refund if you downgrade within 14 days. |
| Features | BContact discovery, pitch templates with open and reply tracking, follow-ups, a shared record of every conversation, a Chrome extension and link monitoring. It covers the whole outreach job, though Starter leaves out bulk sends, auto follow-ups and reports. | CA prospect finder, AI first lines, inbox rotation with warmup, a reply inbox, sequence templates and a scan for links from sites that replied. Outreach end to end, but AI reply sorting waits for Agency and nothing shows links being re-checked later. |
| Ease of use | CNo rating on record. The Chrome extension adds prospects from any page, but you still connect your mailbox, set up projects and build templates before the first pitch goes out. | CNo rating on record. You connect your own mailboxes, let warmup run and build sequences before the first campaign goes out. |
| Platforms and integrations | BWeb plus a Chrome extension, with Gmail, Google Workspace, Microsoft 365, Exchange, Ahrefs and Hunter. There's an API on Professional and Custom. No desktop or phone app. | CWeb only, sending through the Gmail, Google Workspace, Microsoft 365 or SMTP inboxes you connect. The API comes only with Agency at $159 a month billed annually. |

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.
