The email pricing change log

Most tools don't announce price increases — they quietly edit the pricing page. We keep the receipts. Every change below is dated, described, and reflected in our calculators; entries marked reported are changes we verified against the live pricing page without a published effective date.

  1. DeepSeek V4

    DeepSeek roughly triples V4 pricing and moves to peak/off-peak billing

    DeepSeek V4 Flash went from $0.14 in / $0.28 out to $0.44 in / $1.32 out per 1M at peak, and V4 Pro from $0.435 / $0.87 to $1.32 / $3.96 — output rates rose about 4.6x. DeepSeek also introduced time-of-day billing: peak is 01:00-04:00 and 06:00-10:00 UTC, with off-peak (the other 17 hours) at half price. Cache-hit input rose in step, taking V4 Pro's cached discount from roughly 0.8% of its input rate to about 3.3%. DeepSeek remains cheap by frontier-lab standards, but it is no longer an order of magnitude below the field.

  2. OpenAI GPT-5.6

    OpenAI cuts GPT-5.6 Luna five-fold and drops Terra by 20%

    GPT-5.6 Luna fell from $1.00 in / $6.00 out to $0.20 / $1.20 per 1M — a five-fold cut that moves current-generation OpenAI quality into budget-tier pricing. GPT-5.6 Terra dropped from $2.50 / $15.00 to $2.00 / $12.00. Sol, GPT-5.4 Mini and GPT-5.4 Nano were unchanged. Price cuts are rare enough in this category to be worth noting: most 2026 movement has been upward.

  3. MailerLite

    MailerLite raises prices across every tier and cuts its free plan to 250 subscribers

    New pricing took effect June 16, 2026: paid plans rose roughly 10–30% across subscriber tiers, the free plan now covers 250 subscribers (down from 1,000), and the free sending cap dropped to 2,500 emails/month. MailerLite remains one of the cheapest full-featured platforms — but the gap narrowed.

  4. Kit (ConvertKit)

    Kit's free Newsletter plan now caps at 1,000 subscribers

    Kit's pricing page now lists the free plan at up to 1,000 subscribers — many 2026 reviews still cite the older 10,000-subscriber free tier, which no longer appears for new signups. The Creator plan starts at $39/mo at 1,000 subscribers.

  5. Mailchimp

    Mailchimp's free plan shrinks to 250 contacts

    The free tier now covers 250 contacts (down from 500) with 1,000 sends/month — and total contacts, including unsubscribed, count toward the limit. Mailchimp remains the priciest mainstream option as lists grow.

  6. GetResponse

    GetResponse drops its permanent free plan

    GetResponse no longer offers a free-forever plan — new users get a 14-day trial, then must pick a paid tier (Starter from $19/mo at 1,000 contacts). It stays one of the best-value paid options at larger list sizes.

  7. Flodesk

    Flodesk retires its famous flat-rate unlimited plan

    Flodesk's $38/mo unlimited-subscribers plan — its signature differentiator — closed to new customers on December 2, 2025 (existing subscribers were grandfathered). New pricing scales by subscriber count like the rest of the market: Lite from $19/mo at 1,000 subscribers, up to $149/mo at 25,000.

  8. SendGrid

    SendGrid replaces its free plan with a 60-day trial

    The long-running free tier (100 emails/day forever) was retired in favour of a 60-day trial — after it ends, you must move to a paid plan (Essentials from ~$20/mo). Developers wanting a permanent free tier now look to Brevo (300/day) or Resend (3,000/month).
